Drill sharpening jig.

[toglhot]

I normally sharpen drills by hand, but when I need an exact size hole, ie, the shoulder lengths are the same, I use this jig. As you can see, there are lots and lots of bits inside, but it's easy to use and does a good job. Can't remember the last time I used it, but it was interesting to make.

Very impressive,is the grind on that Bit 2 facet.Nicely Done! Storage Box in same Category!

Hahahaaa! JR

This I really like. Wish there were drawings for this.

No, wrong answer. You wish you had a plunger about now JR

toglhot - Can you give us a list of parts and some dimensions for those parts?
This might be an excellent candidate for a CAD Thread

looks good...I too went the V block route as registering off the long helix of the lands needs a long work holding device. Collets (except for small drills) never seemed to fit the bill

Sorry, no dimensions, I don't work from plans, it's all just in my head. All the parts were hand made.

Nice job on the drill jig. I usually sharpen by hand, but there are times when I'd love to have something like that. Well done.

That is really nice. The sharpened drill looks good too. How does the jig move / tilt to grind the heel lower then the cutting edge ??

How do you index it 180 degrees to itself accurately. or do you just eyeball it.?

Nicely done! Maybe you could lend it to a CAD-literate member who would measure and draw it in CAD.

There's something that I don't understand, though: the 1st-facet (cutting) edges appear to be different lengths:


Is that some kind of optical illusion or what?

An illusion. Image is not taken coaxial to the centerline of the drill. Hence the shadow on the NE side of the image.. Light source on the SSW side.

WOW Nice !!! I hope I can study your pictures and make something similar someday. I *do* have the conventional sharpening jig that pivits about its vertical axis but obviously this does not produce facets -- only the factory-style grind.
