Anybody know if I will need a 3.7 or a 4.1 drill bit to mount bindings on my bushwackers? Also, if a ski calls for a 3.7 mil drill bit, is the 12AB tap still used, or is there a different method for making threads on an all wood ski? Thanks.
Binding mount on a Bushwacker
3.5 or 3.6 with no tap on non-metal topsheet
4.1 and tap metal topsheet
Chenzo, Thanks for the reply. Today I removed the demo bindings and it looks like there is going to be some interference with the old holes and the new holes that need to be drilled to mount a Solly s810. Would you know what the proper procedure is to drill out the new holes so that the new screws and binding wont rip out? Can I just move the toe piece forward or aft of the old holes or is there a different procedure. Thanks.
Are you using a paper or metal jig? If you are freehanding it, you can find a paper jig here - http://www.tetongravity.com/forums/showthread.php/153971-Binding-Mount-Paper-Templates
By lining up the jig, you should be able to find a mount area free of old holes. You might end up ahead or behind center.
You will want to plug the old holes - if you dont have plugs you can fill them with 5 min epoxy, or even wood glue.
My rule for the distance between new and old holes is a minimum of 1/8", 1/4" is better.
Yes you can just move the toe, but that heel doesn't have a huge range.
Do one ski at a time, start to finish - so if you screw up, you only screw up one ski.
Alternatively you can install heli-coils or inserts - or have a shop do it.
ya, sorry for the elaborate post. nobody responded to you, so i thought i'd give a quick in depth response. you prolly live somewhere that has open ski areas right now - we are still 3 weeks away from an average early opening around here.
