Ok so I've been searching for plans for a filing jig and I keep coming across threads talking about one made by Brent Finnigan several years ago that is supposed to be a really good design. Whenever I click on a link to go to the pics of his all the links are no good. Does anyone know where I can find the pics of his or use a filing jig that they really like that I can build. At this point anything will help.
Thanks!
 
I have a Bruce Bump carbide edged file guide, and a hardened tool steel file guide that I bought through one of the knife supply houses.

I'm sometimes hesitant to use my newer files, some of which have cost over $20 each, with the carbide guide. I worry that the carbide will knock the sharp cutting edges off of the tips of the file teeth.

For this reason, I've tended to using the hardened steel guides more often than the carbide ones.

Has anyone had the same concerns or experiences? Comments?
 
Yes, i use a hardened steel set i made for my tang shoulders. These are much harder than the files i have and they will knock down the teeth after a couple of uses. The same as the carbide will do. I primarily use the carbide faced jig to work with on the grinders. AO paper will not touch them. You can get very close with minimal work required after grinding for even bevel shoulders.
 
Finally broke down and got one of Bruce's guides. Could kick myself for not doing it sooner. Cost a little more but worth every penny, and will save yourself a lot of headache by having one that works the way it should.
 
Therefore, a "carbide filing guide" should be more accurately stated as being a "carbide grinding guide".

I've found the carbide guide bulky and uncomfortable when grinding and only tried it a couple of times. Maybe I perceived that I had had need for carbide and bought them. I'm a tool junky after-all.

I agree that carbide guides may be a good prescription for some people. Fortunately, I think I've gotten my free-form grinding skill to where I don't need a hardened guide to well locate and define my plunges lines.

For filing applications like slotted guards . . . I'd think that a set of hardened steel file guides at about a 1/2 point below the hardness of of typical file (61-63 Rc?) would be most economical and useful. I'd rather replace one file guide due to wear over a year or two, versus my entire file inventory.

If being used for grinding, then by all means . . . the Bruce Bump guide is of the highest quality and fitment and will serve it's intended purpose.

To this point then, for somebody wanting a sufficient guide for equalizing plunge lines using files, would the hardened guide offered by Jantz (62 RHc) be a good investment?
 
What about simple 1-2-3 blocks? Those are fairly cheap, and useful for other things as well as filing guides.
