Dril Bit Size for mounting Marker plates

post #1 of 4
Thread Starter 

Hi,
does anybody know which one is the correct size for the world cup piston plate? I know it's 9.5mm deep but not sure how wide. I believe it should be 4.1mm but I would like to know for sure before I drill the skis...

Thank you.

-edit- 
I'm installing them on Blizzard GS boards

quick answer -  4.1 x 9.5 and tap:  if the skis have a metal layer at or under the top sheet. - if no metal, 3.5 x 9.5 and no tap.

 

if you have the shim kit (8 shims, - 4 toe,4 heel) and the longer binding screws, you can use for gs all the shims, for sl just use all the toe shims.

Thank you! 
I believe that blizzard race skis have a "titanium" layer somewhere under the top sheet, can anybody confirm this?

If its a sandwich (non-cap) race ski, the metal layer, at/or just below, the topsheet, will be obvious.

 

If you are not sure, drill with a 3.5 first - you should see metal shavings while drilling, if there is metal in the t/s area.  

 

You can also look down the hole, for t/s metal, after you drill 3.5.  

 

If there's metal, re-drill with 4.1 and tap.,
