Title: Nock Filing Jig?
Post by: Interseptor on January 11, 2015, 09:41:00 PM
I saw a jig on one of the bow building video where the bowyer was using a metal clip with groves to file out the nocks.  Has anyone here ever used anything like this to file out nocks?

No I have not seen that.  What I do now and its very effective and quick. I first decide where I want the string nocks then I mark them with a pencil and lightly cut a line with the hack saw, then I use a fine rasp to make a shallow groove. I chuck a bit in my cordless drill and go for it. Quick and painless.     :notworthy:  
Its a no brainer......

Here's a link to a build along I did a while ago with a jig I use.

Eric Krewson the "Gizmo" guy once posted a tip on filing nock grooves and I think crooked stic also does something similar. It looked like a good way to do it so I started doing my version of that way too..after gluing on tip overlays and shaping them I cut the groove into the back side of the tip overlays, then I string bow and using a pencil I mark the sides of overlay and limb sides..unstring bow and file between the marks..you still have to pay attention to the alignment of these grooves, go slow and look often. I only use a chainsaw file for cutting grooves. Then I round them with abrasive cord, then 320 sand paper around file to polish the grooves.

I just made this one out of some 3/8" Phenolic. Works really good.....

That looks like it would work nicely.

Folks,

You have my curiosity up, what angle are you guys using?  Are you just cutting the angle?  Or More?

I have always just used my carpenters square at 45'.  But I also cut both the 45' and the 90'.  I don't know why, it is just what I have always done...

Another tip: Get yourself some Frost Bite chain saw files. They cut better and last longer than the ones designed for cutting string nocks. The ones I got off the big auction site were $15 for 12 files delivered.

Another tool I use is a tile saw blade in a hacksaw frame. These are a little smaller diameter than a normal chainsaw file and the frame makes it really easy to get your first cut accurate and it's a fair bit easier than filing all the way. If you do drift off a little then it's small enough that you have a little 'play' room. If you've got your cut straight then it's a doddle to enlarge it with chainsaw files.
I really like the Stihl chainsaw files. Very good quality.
