Grinding Jig

Here are pictures of my jig. It does flat, hollow, curves, axheads, etc. It has over a dozen pivots and adjustments for multiple set ups. It was made from an old drill press and some ingenuity. They say necessity is the mother on invention.

This front view - 2 pieces of angle iron bolted between 2 plates. You can adjust them up/down & in/out.


This side view shows what I call a "flex head".


This shows 4 folder blades ready for grinding.


The head swings in and out of place on a drill press stand.

Grinding Jig


Hi Gene.

I like the looks of your grinding jig. I'm an aspiring (just starting to buy tools) knifemaker, and one of my biggest fears is that I'll burn through blade blank after blade blank trying to get an even grind. Do you know if there is a grinding jig out there available commercially for use in custom knifemaking? Or anyone else for that matter. Speaking of tools, I'm kind of looking for a used grinder, too. Nothing fancy, just a plain jane 2 x 72 to get me started.

giinder jig


When you grind the blade in the jig is the edge up or down?

Re: giinder jig


Eric, Study the part with the aluminum angle iron.
That flex head is all you need, and it can be made easily.
It is slotted and bolted and does everything you want. It can be made in about 10 minutes and lasts a lifetime. These pictures should help you figure it all out. If you need me, call me.

The grinding is done above centerline, upside down(cutting edge up)

This jig keeps it true to centerline, and takes off the same amount from both sides. A virtually perfect grind, down to 600 grit, and ready to cook.

Re: diagram


Sorry about the wait. Needed Pat to scan it for me so I could put it up here.
Plus - she discovered my 3-year old son had added to the diagram for me.

Just thought I'd mention, Gene uses this jig in his video. That's a great resource, and I recommend it highly.

I'll second Dave's comment. Gene's video is quite good and shows the jig in operation. Looks like a great setup particularly for production work.
