Thread: Tomorrow is another (drill) day.

Looks good, could you show it in use?

Very interesting.

Well done, you've done a good job, however, a little home movie would be appreciated

Ken

Hmmm, well I'll have to work on that one, difficult to hang on to a phone and sharpen a bit at the same time. I'll have to figure out some sort of clamp/holder. But first I'll have to make a slide table - still using the tangential table which is a bit short.

Nice job, Looks like it would be easy to use. I'm guessing the vertical angle is adjusted by the rest on the grinder? or am I misunderstanding how it works..

Very interesting

Some drawings would be nice. And a video of course.

Good work. Beautifully finished.

I bet there won't be a blunt drill in the shed within a day or so!

That's correct, the rake is adjusted by the table angle, I'll be making a table for it today - all going to plan. To make it a little less fiddly, I think a table that can only be set at one of two angles will suffice - I'll have to sit down and work out how to do it first.

I grind the back edge first, a bit of a departure from normal practice but that's the way I do it. The method for use is:

set drill in sharpenener with shoulders horizontal and place sharrpener in table,
adjust table so bit just touches grinding wheel,
bring advance screw up to touch back of bit,
screw 1st lock nut in till touching back of jig and lock in place with 2nd lock nut.
back off advance screw a little and make 1st pass across grinding wheel,
make as many passes as necessary screwing in advance screw at each pass until lock nut contacts back of jig,
turn drill 180 degrees and repeat,
reset table for cutting edge and repeat.

That's the plan anyway, we'll see after a few bits have been through the jig.

Love the simplicity in the design. I think I'll be using that as my free hand grinding ... well the less said the better.

As for the setting of the tool rest I have now removed mine and I am using a tilting vice that I picked up at a garage sale for $45.

It's just like this one except it needs a bit of TLC.

This one is from McJings....$120

For those who asked: the video - sorry for the quality.

For the malcontents, naysayers and doubting Thomases: this video is meant only, to show the drill jig in use. It is not meant as an instructional video on how to sharpen a drill bit, it is not meant to show how (not) to quench a drill bit when sharpening, it is also not meant as a 'safety in the workshed' video.

I am not claiming it to be the be all/end all of drill jigs, I am not claiming it to be the quickest nor the easiest drill jig to use. It is simply a jig I made as a project - nothing else.

It is also not meant as an instructional video on how to make a video. It was made using equipment to hand, namely a notebook camera. I am the Producer, the Director, the Cameraman, the Narrator and the Manufacturer of the drill jig. No professionalism is meant, intended nor is it implied - hence, the dirty hands and fingernails, poor video quality and use of C#!ne$e tools.

This video was made to show 'my' drill jig in use - that is all. Both the grinder and the drill bit are C#!ne$e... Yes I know, had I bought a ‘quality’ drill bit in the first place it wouldn’t have needed sharpening. Similarly, had I bought a ‘quality’ grinder, it would obviously have done a far better job, taking half the time and with much less effort. And then of course there is the sharpening jig itself: no doubt I could have bought a ‘quality’ sharpening jig for the same price as the materials I used to make this poorly designed and poorly executed attempt, it would have done a far better job, taken half the time and effort, been a ‘joy to use’ and of course it would outlive the next three C#!ne$e dynasties – malcontentism is alive and well in my shed…

The jig works for you - fantastic!

If it helps someone on else - even better!

And if some one can help tweak or improve the unit in such a way which respects the offering on the basis of what it is - good again.

Criticizers, trolls and naysayers can insert their heads in a bears bum. If you can,t be nice - say nothing.

I have the Tormek wet wheel system and have borrowed the drill sharpening jig from a mate to see whether I could justify the outlay, which as I'm sure you know is huge.

The pfaffing around required with the Tormek jig is on a par with your system, don't feel bad about your system, I think it's pretty fantastic.

By the way, I watched the video before reading your text. Whilst watching the video I noted near the end of when you were changing the jig from the primary cut to the secondary cut, that your grinder was still spinning. My immediate thought was, "that's got pretty good bearings and seems very balanced as it's still spinning".

Your bench grinder is nothing to be ashamed of. I myself, have a 200mm GMC bench grinder that cost me all of $39.00 it's very good too.

I haven't bought the Tormek drill sharpening jig and unless one comes up second hand at a reasonable price, I probably won't.

Mick.

Probably because it was still on - it's badly out of balance though as you no doubt heard. The jig does it's job: I only use it for sharpening my lathe drills, makes for less wobble and therefore more accurate holes - the others get sharpened by hand/eye.

Hi Th62,

I watched your video with great interest, and learnt some things in the process !

Please don't take this as criticism but could I suggest a modification that would make your jig even better.

My suggestion is to turn the drill holder through 90 degrees so that the drill clamp is at the side and make the drill holder detachable so that it can be inverted on the base without having to loosen it off so that you can turn the drill holder 180 degrees maintaining the drills cutting edge line. Since you said you were going to make another anyway.
