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.

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.

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

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.

vGENE, cAN YOU DRAW A SIMPLE PLAN FOR THIS JIG AS I AM PRETTY THICK HEADED. THANKS sAM

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. :)

Don't you like my CAD drawings?

Ok, you guys know I am not the computer wizard, hehehe

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

Dave

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.

I just ordered Gene's video last night.

Tom, It is on the way today. Thanks

Gene, I appreciate the fast service.
Tom

thanks for the additional info--there is a lot of info in Geno's video, this particular jig is invaluable as you can see in the video.--Dan

I received the video yesterday and have watched it twice already. Excellent job Gene!!!
Tom

Bringing this around for Mongo.

Me either. The link looks good. Other have seen them early in the thread, did they get deleted?

Bob, you know better than to ask me a computer question.:D
They were there, now they are not, sorry.
It was a sketch of two pieces of angle iron(aluminum,3"X3"X1/4") that were slotted on one side and drilled and tapped on the other(1/4X20 threads). They can be used to make adjustments in two directions, in and up.There is just a little flex to load the blades and let go.One side mounted to the work table, and the other mounted to the base solid. It's hard to explain but it is in my video.I show the details, and how to use it.
A homemade grinding jig that cost less than $3.00 dollars.
I'll have to ask Pat to fix the pics.(she is working two jobs right now)

Thanks Gene

Ive got your video,
i'll give it a closer look..

Hi Gene,
Definitely post the pics again, I'd really like to see some up close shots. BTW, the video is excellent! :)

I store the images we use on our web site and was cleaning house. I should have know Gene would "need" them again. I've fixed the pictures and even added a few extra. :)
Forgive me guys.
