a

Making Championship Curling Ice

this video is designed to instruct ice

makers in the proper techniques of

installing tournament curling ice

everything from initial surface

preparation flooding logo placement and

optimization of the speed and curl on

each sheet will be covered the first

step with any arena installation is to

make sure the surface is perfectly level

use a transit for laser level and as em

bony to rough level the existing ice

this helps identify any hills or low

spots on the surface a jet ice water

system has been set up and has been

checked for TDs and pH to make sure that

the water quality is 100% use a rubber

hose that will not mark the ice and coil

it into a figure 8 configuration so that

it will not tangle next we will flood

the ice to level and fill any low spots

on the entire surface we use a stopwatch

at all times so that we know exactly how

many gallons per minute of water we're

putting on the ice

make sure the flooding tube is kept

about 12 inches away from the water

already on the ice ensure the spray is

applied very evenly across the field of

play and therefore the amount of water

on the surface will be distributed and

an even case it will become quickly

visible where the ice is lower water

wants to flow in the low spots if the

ice is completely level it will look

like a mirrored surface this procedure

for a regulation-size

rink should take a minimum of one hour

to one and a half hours a jedi's

painting system has been setup in this

ring jet ice white powder paint is mixed

and will be used to cover the entire

surface with white paint use a small

double nozzle to cover any of the

existing logos on the ice

repeat this step three to four times to

completely cover the logos

once this process is done switch to a 15

foot spoon to cover the entire ice

surface with paint

repeat this step four to five times

until the entire surface is completely

white

once the painting is completed the

barrel needs to be washed thoroughly and

the hoses should be recoiled into a

figure 8 configuration next seal the

entire surface with water do this a

minimum of 12 times with the 15 foot

Jedi spoon the ice temperature must be

constantly monitored during this process

either with the laser gun or a

mechanical thermometer after each spray

the ice will warm up therefore it is

important to wait until the ice cools

the original temperature prior to

applying the next spray a rink layout is

always supplied for every event the

world curling Federation rulebook

outlines the official layout in this

scenario there is a four sheet layout

for a Canadian men's championship in all

rink layouts always start measuring from

the center out to ensure that the design

is Square to the hockey rink you measure

corner to corner yellow wool is being

used to make outside marking lines the

wool is sprayed in with a backpack

sprayer and will attach very quickly as

the water freezes

once this is done a tape measure is used

to measure all of the markings use a

waterproof felt marker to obtain clear

lines on the ice do not kneel on the ice

as it will leave body marks make all

markings and mark them very clearly be

careful not to lose them and be sure to

follow the supply drink layout at all

times once all of the markings are

completed it is time to set up the hacks

the first step is to drill all the

markings that were previously marked

occasionally the markings can wash off

when you apply water therefore drilling

the markings prevents losing them

screws are put into the ice and lines

are tightly tied to the screws so the

lines are clear and accurate always make

sure that the lines are perfectly

straight this will ensure that the hacks

and center pins are in the exact

position locate the hack line marks a

white will line is used to mark the hack

line horizontally across the ice surface

everything is sprayed in with backpack

sprayers screws are drilled into the tee

line markers pink wool is then tied

tightly to the screws and stretched

across the surface the center points of

the house are marked with four small

dots at the spot where the tee line and

center line intersect once this is

completed the hacks are put into place

they must line up with the hack line and

the tee line once the hack is in

position it needs to be sprayed in with

some water the wool guiding lines can

now be removed and center points need to

be drilled a pin is inserted into the

hole and will be used to cut the house

circles in the future the hog lines are

also marked during this stage and

shortly I on the hog will be in stone

a router circle cutter has been cooling

on the ice it is made of aluminum

therefore it is very light as you can

see in this demonstration it works very

well the four routers cut the circles in

just a few minutes and the house is then

ready to paint always make sure there's

someone on hand behind the router

cleaning up all the snow immediately so

that it doesn't stick to the ice in warm

arenas the snow will stick very quickly

the jedis paint is already mixed as per

manufacturer's instructions it is

applied very easily by following the

grooves in the house this can be done

with a curling brush paint roller or a

spraying device rings can also be

installed by laying down paper or

plastic but paint is preferred because

it looks the best here you can see a

paint stick in operation this painting

device is very handy it is simple to use

and does a very beautiful job a 12 foot

circle can be painted in about two to

three minutes a small brake line

connected to a gravity flow can is used

to fill the grooves a different color is

used to provide contrast the hog line is

painted with a heavy four inch brush

following the wool that was previously

installed after all of the houses are

painted a very fine mist is applied to

the surface with a backpack sprayer this

is repeated a minimum of 12 times after

the mists has been completed a fine

nozzle is installed on the hose this

provides a heavier spray and is now

applied and repeated a minimum of 12

times all of the painted areas must be

sealed in this manner

after this is completed we use the 15

foot boom to seal several times again

the boom must be lifted over the newly

installed lines to avoid damaging them

after each seal it is very important to

check the ice temperature always make

sure that it is cooled to the original

temperature prior to applying the next

seal the Canadian curling Association

has supplied a feel of play layout

wool is used to mark the lines on the

ice this can be purchased from any of

the major stores in the community will

is affixed to the ice with a backpack

sprayer and also removes easily if

needed typically small spray cans are

used to tack the wool into place when

that is done and the lines are set a

heavier spray seal can be used to freeze

it in center lines can be installed with

either three lines or two lines in this

case the center line is done with three

lines two blue and one red try to keep

the lines a half inch apart it is

easiest to have someone step on the

lines and someone else sealing them in

any excess line can be cut off with a

utility knife do not seal in the lines

too much in case any wool needs to be

removed in the layout there are some

logos that must be installed later

therefore the wool lines will have to be

removed where the logos are going to be

placed this is very important and can't

be forgotten make sure to precisely trim

and clean the ends of the trimmed wool

the eye on the hog is the device that

electronically determines hog line and

fractions a template has been

manufactured to install the magnetic

strips used to measure violations there

is a small section of wool about one

inch wide being cut out of the lines

that is where the magnetic strip will be

placed in the future the strip is five

feet wide and is laid down against the

template so that it is exactly one-half

of the width of a rock in front of the

hog line this is the center bolt of the

rock at this point the magnetic strip is

laid down and sealed in after all the

lines and magnetic strips have been

installed use the 15-foot boom to seal

several times again it is very important

to seal seal seal Center logos have been

laid flat on a table to settle

previously a small pin was placed in the

center hole to aid in the circle routing

now that pin is removed prepare for

center logo installation a lot of water

needs to be applied with this type of

logo before it is laid down somebody

must watch from the side to make sure

that the logo is square once it has been

applied it must be rolled to make sure

that no air is trapped underneath after

rolling is complete and all air is

removed from under the logo a flooding

pin is installed back into the hole this

pin is taller to allow for flooding

three by three inch square foam is laid

as an outline for all of the tournament

sheets this is one of the best products

to use for borders and is very easy to

work with it is light the rocks bump off

it well and is simple to remove after an

event

this foam is not recommended as a

year-round application in a curling club

but for a special event it is by far the

easiest way to install borders to

install run some water along the edges

and the foam will stick to the ice at

this point only install the perimeter

foam all the way around the four sheets

of ice a heavier spray nozzle is now

used to seal the entire surface this

nozzle puts out a lot of water and it is

almost like a mini flood this is done

three to four times and it will leave a

very nice smooth surface the perimeter

foam is now complete and heavy seals

have been applied to the entire surface

roll is now pulled between each sheet to

align all of the remaining divider foam

this acts as a guide to follow between

each sheet all the remaining foam is

laid out and is being placed on the wall

guidelines soon there will be a total

rink layout with all of the individual

sheets the foam is frozen in place very

quickly with a small amount of water

from a backpack sprayer once all the

foam has been placed and frozen in a

knife is used to cut any excess for

things such as walkways once the foam is

installed the 15-foot boom is used to

slowly flood the ice again this will

seal in all lines foam and paint the ice

installation with all of the lines and

all of the foam is now complete

continue sealing with the boom until all

the remaining wool is below the ice

surface after completing the sealing it

is time to install rock boxes a small

stencil is used with a screwdriver to

mark the line red and yellow wool is

pulled along the mark line using a

backpack sprayer seal in the rock boxes

against the foam on each

a yellow and red Rock logo is placed and

rolled into the rock box area this is

where the rocks will be placed on the

sheet at this point all of the logos

such as the center area and rock boxes

have been completed it is now time to

install large logos the logos need to be

laid out flat so they will stretch out

and we'll lay smoothly on the ice

in the meantime corrugated plastic

stencils are set out to help position

where the logos will be placed using a

screwdriver scribe the ice along the

edge of the stencil the scribe stencil

lines provide a clear location for logo

positioning once this is completed the

logos are put in place plenty of water

is put on the ice and the logo is lined

up with the marks that were previously

scribe once placed firmly and squarely

someone rolls the logos down and pulls

all of the water away so there is no air

trap this is very important trapped air

will cause white spots under the logo

when applying large logos such as one

about 12 feet wide it must be measured

and marked at the center so it can be

installed properly begin by watering and

rolling the center of the logo down

first to ensure that it is square

towards the sheet once this has been

completed roll the rest of the logo down

from the center out until each side is

flat on the ice be sure to thoroughly

apply water as each side is laid down

this will allow the logo to go down very

easily continuously rolling from the

center out and pulling water away will

make the logo go down nice and flat

without any problems and no air trap a

complete installation should look like

this

all of the logos are square and in place

once installed a fine mist is used to

seal in all the logos this is done

several times with a single nozzle fine

mist the next step is to use a

showerhead nozzle like this one and put

on a heavy splash flood spray back and

forth on each individual sheet until all

logos blend in with the ice this is done

three to four times to get a good cover

on each sheet once the splash flood is

complete it is time to start putting

actual hose floods on the ice a flood

statistical sheet is used to record how

many gallons of water

how many floods how many gallons per

minute the water temperature the ice

temperature and all other important

details use an open hose flood with a

flooding tube that has a nice bend on

the end this ensures a nice even water

flow along the ice service without

leaving bubbles or air coming out of the

hose flooding is done evenly at the same

speed across each sheet with a nice wave

of water flowing forward the wave

flowing through the house can be seen

here a minimum of 100 gallons per sheet

will be applied to get a nice even flood

the pressure coming out of this hose

will move the water forward by quite a

good speed the water pressure should be

approximately 10 gallons per minute

always check the temperature speed and

time for each sheet check the flood

speed at the halfway mark to maintain a

consistent flow throughout the process

flooding will be done on each sheet

several times until the ice is

completely flat continue to time each

open hose flood to determine how many

gallons of water are used when the flood

is completed it should look like a

perfect mirror

it is now time for the initial ice

preparation here are some of the tools

of the trade that are needed to

condition the ice pebble heads pH

testers water temperature testers

different peddling cans a hot water tank

and a Jedi system with deionized water

this is hooked directly to the hot water

tank so that a hot and cold water mix

can be used use an ice scraper and a

whiteboard to record and control what is

scraped at all times the scraper must be

checked thoroughly before it is ready

for peddling and scraping use a gravity

peddling can with straight cold water to

apply the first pebble this should be a

double pebble once the second pebble is

finished bring out a new scraper blade

that has not been used and make sure it

is perfectly straight if this is not the

case some alterations will need to be

done on the blade with a small honing

stone there is a polar on top of the

blade that needs to be adjusted

sometimes to get the scraper blade

perfectly straight

one person is monitoring the front and

one person is driving at all times this

allows for a perfect view of what is

happening with the snow in front of the

blade sometimes adjustments will have to

be made on the fly to maintain an even

scrape always watch the ice to ensure

that the pebble is cut perfectly

straight continue peddling and then

scraping again to get the ice flat this

will take out any uneven spots on the

ice surface keep the ice clean at all

times with mops and brooms before

someone reapplies the pebble and scrapes

again this is usually repeated about 12

to 15 times before the ice surface is

completely leveled during this process

check the overlap of each scrape one

side of the blade has more snow than the

other side because on each pass some of

the blade overlaps the last scrape

continue peddling and scraping until the

sheet is perf

we level from one side to the other

clear the snow from in front of the

scraper regularly during each pass

peddling up the outsides of the sheet

will help make it level so the ice curls

outside in the same as inside out this

is a very important task in the

preparation of tournament ice the ice

must curl the same weather that is

inside out or outside in the ice should

now be perfectly leveled and ready for

the final steps of game preparation

apply a double pebble to each sheet with

jet ice water the pebble stands up nice

and high now scrape this pebble off to

make certain the ice is still level

always remember to change the scraping

patterns and keep track of the patterns

on a white board on top of the scraper

now a second pebble is applied that is

larger in size use the scraper to nip

the pebble this is done very gently and

should leave very little snow in front

of a blade only cut off the heads of the

pebble and this will make the ice

surface fast and help it curl right from

the start after each pass collect the

snow put it into a dustpan and melt the

snow in a microwave then measure the

amount of water to determine that the

right amount of snow has been taken off

to achieve perfect ice conditions

the ice preparation is now complete now

the task is to make sure that the ice

making machinery and the ice

temperatures are staying consistent

check the compressor room to make sure

that all of the compressors are in

proper working order check to verify

that the high-pressure temperature and

the suction pressure temperature are in

the right range and that the chiller is

putting out the right brine temperature

all of these things are monitored 24/7 a

computer system is set up and relied on

during the events this system will

monitor ice temperature air temperature

brien temperature humidity levels and

all other critical stats these

temperatures are being monitored by the

wireless ice monitoring system called I

on the ice this system also is

configured to facilitate access to the

ice conditions from anywhere anytime on

cell phones or on any computer it also

has a built-in alarm that will notify

the ice makers of any changing

conditions the ice installation is now

complete and the event can proceed with

perfect ice it is now the ice makers job

to monitor the ice conditions throughout

the event making certain that the ice

stays perfect
