Q. WHAT IS THE DIFFERENCE BETWEEN TILESET/AILSET AND TILESERT/AILSERT CURLING STONES?
A. There is no difference in the way the
stones run, because they have identical running edges and cups, and identical
material when setting or inserting the stones.
The Tileset/Ailset process, protected by
our patent #2,083,446, is installed in the following manner;
We slice 1/2 inch of granite off one surface
of the club's curling stone and using a special granite epoxy adhesive,
we adhere a disc of Porcelain tile or Blue Hone Ailsa Craig granite to
this surface. We then reshape this surface, providing a 5 inch diameter
running edge with a 1/4 inch depth cup. When the polishing is completed
and while the stone is rotating in the chuck, we touch the surface of the
running edge with a 6 inch square, machined brass plate. The brass transfers
a thin line onto the running edge, and by examining this line, we can assure
that the running edge is perfect. Should there be any problems in the grinding
or polishing the brass line would be irregular, which is usually caused
by a worn bearing.
The following are some very elementary reasons
why Tileset/Ailset is superior to Tilesert/Ailsert.
On a Tilesert/Ailsert, the inserted disc
material (Tile or Blue Hone) has a different expansion and contraction
rate, to that of the stone to which it is attached. This could cause a
very serious problem if the spacing between the inserted disc is not perfectly
centered.
This is not a problem with our patented Tileset/Ailset.
The seam of adhesive on a "Tileset/Ailset" stone
is around the shoulder of the stone and away from the ice surface.
The seam of adhesive on a "Tilesert/Ailsert"
stone (6 inches diameter) is very close to the running edge (5 inches diameter)
therefore, it is possible to get damaged and become dislodged.
Also, when pressing the "Tilesert/Ailsert" disc
into the cored hole of the stone, air tends to get trapped in the adhesive
leaving voids, which in turn causes the bond to be weaker than that of
the Tileset/Ailset.
Also, with the "Tileset/Ailset" the dense material
is a complete slab all across the bottom of the stone nullifying chances
of fractures.
The Blue Hone granite has been quarried from
the Island of Ailsa Craig but this Island has now been designated as a
bird sanctuary, and quarrying has not been allowed for some years.
MORE ABOUT PORCELAIN CERAMIC RUNNING SURFACES
FOR CURLING STONES
Due to the closing of the quarry on the
Island Of Ailsa Craig in Scotland we have been searching for a granite
that would be as suitable or better than the Blue Hone granite now being
used for running surfaces of curling stones.
In 1993 we discovered a very dense granite which
was quarried in Eastern Canada, and after extensive testing found it to
have the same qualities as Blue Hone. Since there still was an abundance
of old, mismatched, chipped, Blue Hone curling stones available, we decided
to purchase them from curling clubs and recycle them, by cutting them into
slabs for Ailsets and Ailserts.
These old Blue Hones stones they are becoming
somewhat difficult to find, as the stock is becoming depleted.
We could still rely on the supply of the granite
from Eastern Canada, but since this quarry is not presently in production,
it would have been expensive for us to have it re-opened.
Along with our search for a suitable or better
granite we have also been continually searching for other materials to
be used for the running surfaces. This included a variety of composites
and alloys.
After extensive testing "Porcelain Ceramic" proved
beyond our expectations to not only be as suitable as the Blue Hone granite,
but far superior to it.
Here are the specifications and reasons that
prove the Porcelain Ceramic to be superior for use as a running surface
for curling stones.
1. Extremely low moisture absorption, less than
.03%
2. Unbelievable abrasion resistance.
3. No calcium deposits, (white specks) to become
dislodged, causing inconsistent running of a curling stone.
4. Endless supply for the future.
5. As the supply of Blue Hone granite diminished
the price increased, therefore the cost may have soon become out of reach
for most curling clubs.
6. Incomparable fracture resistance (guaranteed
for an extra 10 years.)
If you have any doubts about the durability
or wearability of Porcelain when used on curling stone running surfaces,
consider and compare it in the following applications:
1. Protective shielding against extreme heat
and cold, on the U.S. Space shuttle.
2. Flooring for manufacturing plants and warehouses,
where heavy production machinery is used, also where solid rubber and metal
wheeled fork lifts are used.
3. Lining for industrial furnaces and foundries
.
4. Tools, jigs, and abrasives.
5. Turbine blades, precision instrument parts.
6. Artificial teeth, and bones.
7. Light emitting and laser diodes.
Considering all of the above information, if
there still is any doubt in the minds of curling club executive about choosing
Porcelain tile, instead of Blue Hone, we would urge that they wait one
more season before resurfacing their stones. We will supply two or more
Tileset stones, free of charge for trial.
Q. WE HAVE HAD ENQUIRIES ABOUT HOW CRUCIAL
IT IS THAT
the running edges be exactly 5 inches diameter.
the cup be deeper than 1/4". the weight of the stones be within ounces
of each other, if not should they be weighed and matched?
A. WE CONDUCTED MANY TESTS USING:
Three stones, one with a 4 inch diameter running
edge, one with a 5 inch diameter running edge and one with a 5 inch diameter
running edge, all three stones were the same weight. Three stones with
one weighing 36 lbs 6 ounces, one weighing 40 lbs 2 ounces and one weighing
48 lbs 12 ounces, all three stones had the same diameter running surface.
Two stones weighing 39 lbs 6 ounces, one with
3/16 inch cup depth and one with inch cup depth. All these eight stones
had newly reconditioned running edges with the exact same contours.
The result was that there was absolutely no difference
in the amount of curl or speed of all of these stones. The same test was
conducted again in June of 2001 at the Winnipeg Winter Club, and the test
was witnessed by two National Ice Technicians, and again the results were
the same. Should anyone doubt this or be interested in seeing it, we would
be happy to conduct this test in their presence. Contact us and we will
arrange it.
WHAT IS TILESET AND TILESERT?
Prior to this season it was common to use the
term "Ailset" and "Ailsert" when discussing the refurbishing of curling
stones by installing a Blue Hone granite running surface onto stones.
With the discovery and totally successful testing
of Porcelain Ceramic material, it is now necessary to make a further explanation.
We have a patent pending on the use of Porcelain
for curling stone running surfaces and we are brand naming the porcelain
as "Tileset" and "Tilesert" to avoid confusion.
The term "Ailset" meant that Blue Hone Ailsa
Craig granite was "set" or adhered to the running surface of the stone
and "Ailsert" meant that the Blue Hone Ailsa Craig granite was "inserted"
into the curling stone. Tileset will be installed the same way as Ailset,
and Tilesert the same as Ailsert.
Q. WHAT IS FUDGING AND WHAT CAUSES IT?
A. If you have watched the major events
on television in the past few years, you will have noted that there is
a lot of mention by the commentators and by the players about the so called
"fudging" or loss of pebble down the slide path at both ends of the curling
ice. In our tests we have proven that the major cause of the loss of this
pebble is caused by the stones as they are delivered down that path with
every shot. Stones that have a prominent scoop on the inside of the cup,
tend to cause excessive wear of the pebble, due to the relatively sharp
inner lip of the running edge. Think about it, all stone manufacturers
have a gradual contour from the shoulder of the stone to the outside of
the running edge. So why not have the exact same contour from the running
edge inward, instead of a scoop and lip. Furthermore many of the top curlers
are complaining about these stones with scooped cups. During the delivery,
the stones grab the pebble, which can be felt with their fingers before
the release. Another complaint is that if a definite spin is not put on
the turn, the stones will "pick" and/or lose the turn.
In 1989, when we first developed our stone grinding
machine, we conducted countless tests changing the contour of the running
edge and after months of tests and changes, proved that the best running
stones had a gradual contour from the outside, to the running edge, and
the same contour from the running edge, inward.
Q. HOW DO YOU GET THE HIGH GLOSS POLISHED FINISH
ON CURLING STONES?
A. This is a very good and important question.
When we have completed the grinding process on stones, the surface is so
smooth that only a slight buffing with four different compounds of polishing
bricks is required.
We originally tried polishing by spinning the
stone on a turntable at high speed. We would then press a hinged arm onto
the stone, which was covered with sheepskin. This sheepskin was loaded
with a wet "mud", a polishing compound. We would let the stone spin for
approximately 30 minutes, at which time the mud compound would become totally
dry. The stone would then be so hot from the friction that when water was
applied to cool the stone for removal, the water would sizzle and steam.
We found that this method of polishing was less expensive but that resulted
in severe damage to the surface of the stone. This damage was not visible,
but it caused premature pitting of the granite. We immediately ceased using
this method of polishing. In our method of grinding, and polishing there
is never any heat used, in fact, the stone is always cold.
In 1998 we reconditioned two sheets of Red Trevor
stones for a small club in Saskatchewan. Two of their curling members brought
the stones to our Winnipeg plant, stayed a few days and took the stones
back. The stones were placed on corrugated cardboard on the floor of their
pickup truck. Three days later we received a phone call informing us that
four stones had become damaged. Apparently the driver had flipped a lit
cigarette out the window, it landed between the four stones, the cardboard
caught fire and in turn burned the four stones. The stone shown here is
one of the four stones, and you can see the rough, scorched area which
is about 1 1/4 inches in diameter. All four stones had to be replaced.
This confirmed my theory that heat that is built up in polishing the stones,
does cause pitting.
Q. WHAT CAUSES STONES TO JUMP ON THE IMPACT
OF A TAKE-OUT?
A. The simple answer is that the striking
bands are too convex. There was a serious concern when new stones were
used at a major curling event, in 1998. These stones jumped or "saucered"
on the impact of a take-out shot. This not only caused bruising of the
ice, but likely caused an abnormal finish to the travel of the stone. Once
these bands flattened through wear, the saucering stopped. There are some
who say that a rounded striking band is better so we will let you be the
judge. Once the convex or rounded area has worn flat, the stones will start
making contact on the polished area. By convexing the band, a lot of material
is being removed leaving very little surface contact between two stones.
If the impact occurs on the polished area of the stone, the granite will
readily chip.
Q. IS THERE A GUARANTEE ON RECONDITIONING AND
REFURBISHING OF CURLING STONES?
A. Yes, the following is our guarantee
which has been in place from the first day that we started reconditioning
stones. With the introduction of the Porcelain Ceramic material, our Tileset
and Tilesert guarantee will be extended from 10 years to 20 years. You
will note that our guarantee is straight forward and contains no double
talk.
Q. WHAT IS INVOLVED IN REPROTRUDING THE STRIKING
BANDS?
A. When we reprotrude the striking band,
we leave the flattened or worn area as is. Using a diamond tooling, we
remove a small rim of granite above and below the striking band. This procedure
stops the stones from making contact on the polished area above and below
the band. Even in a busy curling rink, reprotruding with our method would
not be required again for 30 years or more. If instead, 1/4 to 1/2 lb of
granite is removed from the striking band, in order to make it convex,
there would in fact be less granite there, and the band would soon wear
to the point that it is again making contact on the polished area. So what
do you get with a convex striking band? Jumping or saucering stones and
soon thereafter, chipping when the small amount of convex surface on the
band wears away and the stone again makes contact on the polished area.
The stone pictured here shows the proper reprotrusion of the striking band.
GUARANTEE OF MATERIALS AND WORKMANSHIP
THE FOLLOWING IS EXACTLY WHAT WE GUARANTEE:
A totally precision running edge on both sides
of the stones, with absolutely no so called "break-in" period whereas the
stones would tend to run heavy or inconsistent.
If the stones are matched sheets (16 stones)
they will all run identical after we recondition them and there is no need
to match them in pairs.
We do not guarantee against pitting of curling
stones because this is totally beyond our control, unless the granite or
material is the non-absorbent type, (i.e.) Porcelain Tile or Blue Hone
Ailsa Craig. We use the Porcelain Tile and Blue Hone granite in our process
of installing a new running surface onto curling stones, and in this case
we do guarantee against pitting due to moisture absorption. We also guarantee
against separation or breakage of the new surface and of the epoxy adhesive.
Our Ailset and Ailsert guarantee is in effect for 10 years. Our Tileset
and Tilesert is guaranteed for 20 years.
This guarantee will be null and void if proper
care and storage of the stones is not maintained.
To assure a complete understanding of our guarantee
it is very important that you read the pages under the heading of "Tips
and Suggestions on Stone Reconditioning" also "Care and Storage of Curling
Stones", and also "Our Method of Reconditioning Stones."
If for some reason these are not included you
should insist on reading them before getting any work performed on your
stones.
DESCRIPTION OF VARIOUS TYPES OF STONES
BLUE HONE AILSA CRAIG: Usually a plain or marbled grey color although some have brown, pink, blue or green shades. One of the original granites used for stones, it was the best for a running edge because it is so dense it doesn't readily absorb moisture or pit. See our information on the Tileset and Tilesert stones. Unfortunately, it was not so good as a striking band because it is so dense that it would eventually break away upon impact and cause break out on the band which appeared like knots in wood. Another problem was the calcium deposits (white spots) which tended to wear or dislodge, causing inconsistent running of the stones. Some of these stones may be over 70 years old and the older stones were bought in pairs by the curlers. At that time the sizes, shapes and weights varied from pair to pair because there was no regulation as to size and weight.
COMMON AILSA CRAIG: Usually green shade with Robin egg black speckle, quarried from the same island as Blue Hone Ailsa Craig. It is not a dense granite, therefore, it didn't break out on the striking band as bad as the Blue Hone but it does absorb moisture on the running edge, and consequently is very prone to pitting.
RED TREVOR STONES: Usually have a reddish or brown shade, are great as a striking band but do absorb moisture into the running edge, eventually pitting, which causes the stone to run inconsistent. Quarried in North Wales, U.K.
BLUE TREVOR STONES: Some are light grey, dark grey, or dark blue. This granite is quarried from the same quarry as Red Trevors, it usually is slightly more absorbent than the Red Trevors on the running edge.
KEENEY STONE: Usually a sandy brown color with square shaped shoulders. Poor granite because it is very brittle causing early wear on the striking band and also readily absorbs moisture into the running edge causing pitting and flaking.
INDIAN GRANITE: Looks similar to Grey Trevor,
is very similar to the Keeney in respect to early wear on striking band
and absorption of moisture into running edge.
There are also a few other types of granite stones
in use, some are a very glassy black color. This is very poor granite.
CARE AND STORAGE OF CURLING STONES
Curling stones are the most important piece of
equipment that a curler uses. No brush or broom, no matter how well swept,
can correct the travel of a stone that runs inconsistent.
Very often this is not taken into consideration
by the curling club executive. In their wisdom they will spend thousands
of dollars on renovations of the Club Room, Bar or Locker Rooms, meanwhile
the curling stones are in very poor condition.
The poor condition of the stones may be:
Pitted running edges; caused by absorption of
moisture which freezes in the granite, expands and then dislodges particles
of granite.
Flat and/or broken striking bands; usually caused
by long wear. The flat or broken striking band on one stone will damage
the striking bands of all the other stones on that particular sheet of
ice. This damage is caused every time the flat spot on the damaged stone
hits the other stones making contact with the shiny area above and/or below
the striking band on the good stones. This shiny area will eventually chip
out causing irreparable damage. The striking bands should be re-protruded
as soon as possible before any more damage is caused to the good stones.
DO'S AND DON'TS
1. Do turn stones each season for even wear.
2. Do leave them on the ice on a thin, ribbed,
moisture proof mat at all times. If stones are removed for a short time
in order to clean the ice surface, be sure to properly cool them to ice
temperature before using them again by setting them on the thin, ribbed,
moisture proof mat on the ice surface.
3. Don't ever set or play stones on wet ice.
4. Don't store stones on the walkway or back
boards. Any slight rise in temperature will be absorbed by the stones causing
them to melt in and absorb moisture, and this also will cause stones to
run heavier. Sometimes the melt in is so slight that it may not be readily
noticeable nevertheless, it does happen.
5. Don't pile stones on top of each other or
on any abrasive surface.
6. Don't allow persons to deliver two stones
in motion at the same time toward each other, because if the stones make
a head-on contact it is very likely that they will break under this abnormal
impact. (See the picture of the broken Common Ailsa Craig stone)
7. Should ice surface become wet, due to freezer
plant failure, don't remove the stones from the moisture proof mat until
ice is completely re-frozen. If plant has shut down long enough to allow
the melt to overflow the moisture proof mat, the stones must be removed,
properly dried, and re-cooled as explained in No.2
8. Do make sure that stones are dry before placing
them on the ribbed, moisture proof mat on the ice surface. Anytime a lot
of ice flooding is being done, there can be an extreme amount of humidity
in the rink, which condenses on the cool curling stones, and runs off the
stone onto the moisture proof mat. The ribs in the mat will provide some
space for the moisture to run off. A close inspection should be made to
assure that the running surface is dry, if not, the stones must be removed
from mat, properly dried and re-cooled as explained in No.2.
TIPS AND SUGGESTIONS ON STONE RECONDITIONING
/ REFURBISHING
Before choosing a Company to recondition your
curling stones we suggest you read and seriously consider the following
-
Get a list of at least five curling clubs that
have recently had stones reconditioned or refurbished by the Company and
contact the club executive or icemaker. If the stones had been reconditioned
some seasons earlier it is important that you ask how the stones reacted
from the start on each side, and if there was a "break-in period" before
the stones ran consistent and/or keen.
Have the Company recondition or refurbish at
least two of your Club's spare stones and have many of your club curlers
test these stones to check if they run keen and/or consistent. If your
Club does not have two spare stones, insist that they provide two newly
reconditioned or refurbished stones on a loan basis for trial. Inspect
the running edge of the loaner stones, if they show obvious wear, it is
unlikely that they have been newly reconditioned.
Insist on a written and signed quotation. Ask
if this quote is subject to "change upon inspection or type of stone",
or if there will be any "assessment of travel expenses". If the reconditioning
is not performed at your Club you should get a quotation of freight charges.
Ask if the Company is actually going to recondition
or refurbish the stones or just re-polish or sandpaper them.
Ask if the company's quote includes reconditioning
of both sides of the stones. Your Club's stones may only be cupped on one
side and the Company may not have the proper equipment to cup the other
side, consequently, it will not be done.
Check accessibility of contact with the responsible
person in the Company in case there should be any problems with the stones
after they have been reconditioned (i.e.) does the Company have an office
open 12 months of every year, or is there just a telephone answering service
or telephone message recorder.
In most cases there is a period of ten years
or more between the time that Curling Clubs have the stones reconditioned.
A Company that not only reconditions stones, but also sells a complete
line of products to the Curling Club, would not likely jeopardize these
sales by providing poor workmanship in the reconditioning or refurbishing
of stones.
Check if the Company has local or regional representation
across Canada and U.S.A. in order to assure fast service in case of any
problems.
Insist on a written guarantee in plain, straight
forward language, as to exactly what is covered in the guarantee. Beware
of double talk.
Ask what type of equipment will be used to recondition
and polish the stones (i.e.) will precision diamond grinding and polishing
wheels be used, or instead, will they be using silicone carbon wheels?
Will there be a lot of heat built up by using compounds to polish instead
of diamond wheels? Is their equipment portable or light weight allowing
vibrations to cause imperfections in the running edge?
OUR METHOD OF RECONDITIONING STONES
1. We do not use Silicone Carbon grinding wheels,
which we find provide a very inconsistent running edge. We instead use
Diamond Segment grinding wheels which are totally precision.
2. We do not use Silicone Carbon sanding discs,
or honing stones or polishing compounds. We find these can cause an extreme
amount of heat build up, increasing the possibility of "cooking" or "scorching"
and causing early pitting. These polishing methods could also cause stones
to run inconsistent because they are not precision. We instead use Diamond
Segment polishing wheels which leave a totally precision finish and there
is absolutely no heat build up whatsoever.
3. We do not have a light weight, portable reconditioning
machine, because we found that unless the machine is extremely rigid and
well framed, the slightest vibration will cause an inferior running edge.
Our machine weighs over 1,000 lbs. and is lag bolted to the concrete floor
of our shop. In the year 2000, we upgraded our refurbishing and reconditioning
machinery, with state-of-the-art, computerized equipment.
4. We do not fasten the stone to the turntable
of the grinder or polisher by using a stone bolt through the centre of
the stone. We found that many of the holes through the stones are not totally
centered and therefore the grinding wheel would not properly centre the
running edge to the circumference of the stone. Our stones are held secure
to the turntable by use of adjustable jaws which clamp at the circumference
of the stone thereby totally centering the stone to the grinding wheel.
This method also allows us to recondition the stone right to the center
of the cup without cutting off any stone bolts.
Because we provide a totally precision running
edge, there is absolutely no so called "break-in period" whereas the stones
run inconsistent or heavy, not even on the first delivery of the stone.
MORE RECENT QUESTIONS AND ANSWERS:
Q. I recently read on the www.usacurl.org
website that if stones have a shallow cup or no cup at all, they cannot
hold a 5 inch diameter, and thus become inconsistent very quickly, probably
in less than 3 seasons. Do you agree with this?
A. I checked this website and suggest
that you contact the author on this, nevertheless this is my answer to
your question; There is no reason to have a 5 inch diameter running edge,
wear inward only. If the running edge wears both inward and outward, equally,
the centre of the running edge will always be constant at 5 inches. Regarding
the stone becoming inconsistent, I doubt that a test has been conducted,
therefore where is this conclusion coming from or who did the test? This
article also states that "if the stones are not highly polished, premature
pitting will occur", and further on in this article, it states that "The
final operation is the pre-break-in" is performed by removing the so called
"highly polished" finish on the running edge. This is usually done with
sandpaper, so if the polished finish is being removed from the running
edge, according to their information, moisture will penetrate the stones
causing premature pitting, perhaps you can have them also explain this
contradiction.
Another question we received regarding an article
in www.usacurl.org was in reference to "proper freeze-down of curling stones".
Q. In the article " proper freeze-down
of curling stones" we are instructed to test whether the stones are properly
cooled by " setting one or two stones onto the ice and leave them for 15
minutes. Then inspect the ice surface. If the pebble has been melted flat
or the stone has left a ring on the ice, more cool down is required." My
question is this; If the two stones that are set onto the ice, do melt
in, would this melt in not cause absorption of moisture into the running
edge and subsequently, pitting?
A. Absolutely, if you are going to use
this test, it is extremely important that a piece of polyethylene be placed
between the test stones and the ice surface, to protect the absorption.
Q. I have a brochure from a supplier of
curling stones and I am confused on what I see and read. On one page it
states "If it is keanie or common green ailsa craig stones, reconditioning
is not recommended." I assume the reason it is not recommended is because
these granites are prone to pitting. On the adjacent page in this same
brochure they picture a 25 lbs, Keanie Junior stone and 25 lbs Common Green
Junior stone. Why would it not be advisable to recondition the regular
club rocks, but be okay to use this same granite for Junior rocks?
A. We would never recommend that Junior
stones be manufactured using Keeney or Common Ailsa Craig granite, unless
they have a running surface of Porcelain Tile or Blue Hone Granite. Junior
stones are off of the ice most of the time and are subjected to freeze/thaw
conditions every time they are moved back onto the ice. When moisture is
absorbed into the running surface of stones it expands 9% when it freezes.
This expansion of the moisture causes particles of granite to dislodge
and in a very short time the stones will run very inconsistent and heavy.
Our Junior stones have Porcelain Tile or Blue Hone running surfaces, and
we guarantee them against pitting. BUYER BEWARE; If you purchase any stones,
especially Junior stones, insist on a written and signed guarantee that
your club would receive full compensation should pitting occur.
Q. I attended the Brier at Edmonton and
Saskatoon and was surprised to see the curlers matching and switching the
stones around, during the pre-game practice and also some during the game.
We are told by the media that these stones are so great, so what is this
all about?
A. I have also noticed this and thought
that all the matching and switching of stones was just a mental thing on
behalf of the curlers. In this summer of 2001 I blue printed fourteen of
the stones used in these Briers. The Blue Hone granite inserts in these
stones have a lot of voids or pits in the running surface, which I am sure
is the cause of all the inconsistencies. These voids or pits are caused
when the calcium deposits in the Blue Hone granite becomes dislodged.
Q. I noticed on T.V. that the rocks used
at the Saskatoon Brier appear to have breaks or hollow spots on the area
where they contact each other.
A. This area is called the striking band,
these stones have convex striking bands, and this is not unusual on this
type of band. This is another reason why we don't recommend a convex striking
band.
Q. Could you tell me how to prepare the
ice surface for our 25 lb Junior curling stones.
A. All too often, icemakers don't consider
that the weight of Junior sized curling stones, usually 25 lbs are almost
40% lighter in weight than the 40 lb adult size stones.
Due to the lower weight of the Junior stones,
in most cases, the pebble will have worn down very little, even after 8
ends have been played. With this in mind, many icemakers don't pebble prior
to the start of Junior games. This will likely cause the stones to run
inconsistent and/or heavy, and curl less.
We suggest the following preparation of the
stones and ice surface:
1. Properly cool the stones to the same temperature
as the ice surface. If stones are not stored on the ice at all times they
will likely be warmer and will definitely run heavier.
2. Sweep or mop the ice.
3. Pebble the complete sheet. You may have to
experiment by applying more or less pebble and by applying a finer or coarser
pebble. This will vary because conditions such as ice surface temperature,
type of running edge on the stones, purity of water, etc., can be very
different from one curling rink to another.
4. Using a wooden frame rack around a dozen or
more adult stones, run them over the complete surface of the ice to break
in the pebble.
5. Sweep or mop the complete ice surface again
to remove the snow that results from running the stones.
Q. Some T.V. commentators previously announced
that the ice technicians claimed the shade of grey or light blue paint
down the sweeping area caused "fudging" because this darker color or area
of the ice absorbed heat from the T.V. lights and spectators. This area
is no longer being painted, and now the commentators are saying it is the
"slide path" that is causing the stones to fudge. What are your thoughts
on this?
A. I have heard the same excuse, and apparently
the commentators have been told by the icemakers that the colored areas
are 5 degrees Fahrenheit warmer. I personally have a laser thermometer
gun, for which I paid over $1200.00 and know that it is very accurate.
On over 100 occasions, I have taken a comparison reading of the surface
temperature of the ice, on the dark painted areas and on the white areas.
I defy anyone to show me where the surface temperature was even a degree
Fahrenheit warmer on the dark painted surface. I believe it was just an
excuse to cover up the fact that they are using stones that caused the
pebble to prematurely wear down, which in turn causes their terminology
called "fudging".
