to make a jig you need 4 things
a) calipers
b) computer with a cad program and a printer that can do 11x17
c) the bindings in question
d) the boots you want to mount
step 1
carefully measure the binding hole pattern and write it down
remeasure, verify
remeasure, verify
cross check your numbers with metric values by converting them for a sanity check
if its a number that converts to 24.93mm, its probably actually 25mm
see what 25mm is in inches, and double check your measurement to see if its plausible, if its not, stick with what you have
step 2
set your bindings on a table, make sure your heel is centered in its track, and place your boot in them as close as you can to how you think theyd be mounted on a real ski. this part is tricky and very by feel
measure the distance from the toe of your boot to either one of the holes of your toe peice, or something on the toe peice that you can relate to the hole pattern. you're looking to get a relative distance so you know how much to offset the toe on the template.
similarly, take a measurement on the heel to provide a sanity check down the road as well as to provide a relative placement on the template.
step 3
go into cad, draw the toe and heel pattern centered about one long center line
locate the toe\heel patterns relative to one another based off the measurements you took in step 2
double check this with your BSL by drawing a line to verify it fits and is relatively good spot
check your BSL center on the cad and compare it with your setup in step 2. compare it to something like a hole on the toe peice since thats what sets your center and is the more critical of the two peices.
step 4
add in dimensions on your cad, print it off 1:1 scale on an 11x17 paper (everything but the most squatch of sizes should fit fine)
lay out the template, place your bindings on it, and double check that everything lines up, or verify with a jig if you can get access to one like at a ski shop or something.
place your boot in there also, and double check that the BSL line you drew on the CAD in Step 3 matches with the one on your boot. (forget about the heel peice and just set it aside during this step)
I also like to draw a toe line to verify that the boot is correct in its relative position to the toe peice in my cad
step 5
drink some beer because at this point its probably been about an hour if youve done this before, and more like 3-4 if you havent
step 6
go back to your cad model
clean things up
add cross hairs to your circles you drew for the toe\heel pattern
add a BSL line if you havent
add a toe line if you havent
add a heel line if you want
add dimensions on everything of worth (gives a great way to dbl check that the template prints 1:1)
print file to pdf, and save
done
it takes a while, but onec its done, mounting is really easy so long as you follow good shop practice when working with the paper jig. Ive mounted probably about 7-8 dynafits and 6-7 sollys with mine and have had no trouble, and others have used them with similar results. I can layout and drill dynafit mount now in 20 minutes (this is not counting the actual putting in glue, screwing in the bindings, and setting forward position of the heel)
