Nock

[bow101]

Been using a 7/32 round file for nocks.......what size most of you use..?

What do you make your string out of?

[JW_Halverson]

I use a tile saw blade.

Using B-50 Dacron KS5.

Ya....I think those are somewhat smaller than 7/32...

Easier, in my experience, to widen a narrow nock than it is to close off one that is too wide. 

[bow101]

Oh no doubt,  do you think  JW 7/32 is to large.?

I use 1/8" round files. I believe they're for sharpening chainsaw blades. I also use a 1/8" round tile cutting hacksaw for making the initial groove.

I use a 7/32 round file on all my bows. It works fine for me. I think it's just a matter of preference. Whatever works for you is good.        Dale

I use a 5/32 chain saw file for mine.

I'm like pappy with the chain saw file but the best nock file I ever had was a 4" Nicholson rat tail. Not the 6" version you normally see in most hardware stores. That ones 2 big, but the 4" was PERFECT!

I use a chain saw file too. Jawge

I have a 5/32 I use but I had to widen the nicks on both of the bows I made hemp strings for, the same strength string made of hemp was thicker than a B-50 string.

I use a tile saw blade.

Me too! 
They are dirt cheap too. I finish off with a round needle file, but they tend to clog.

The tile saw blade is much faster than a chainsaw sharpening file, that way you can hurry up and get your mistakes over with faster.

i use a scroll saw, sandpaper and a sharp knife and sometimes a sarrated flint flake and sandstone when i feel like going really slow
