I saw the plan for this in Shop Notes. You did a great job on making it. Thanks for the video demonstration.

Thanks for the demo video. I now have a new jig to build. I have that same drill press, does this jig work best at slow speed?

Hey guys,

I had to pull the video down and make a change to the music due to possible copyright infringement. The world is getting crazy. The new video will be up soon.

Thank you for the comments.

There we go. Back up. This time it is me playing the guitar so no copyright infringement. To help offset costs, I monetized the video. I can not ask you to click on the ads but I usually let the pre-ads run for 30 seconds, to help out the video maker. :)

One thing I failed to mention in the video: I filed the edge off the chisel to make it dull and to give me a nice clean edge with no chips to start with. This shows how quickly you can put a razor’s edge on your tools.

What rpm do you sharpen with this system?

The original author of the Shop Notes version used a full sized drill press that was capable of a low speed of 250 rpm. He used off-the-shelf pulleys of equal size so the rpm of the sharpening disk would be the same 250 rpm. My drill press has a low speed of 650 rpm. Fearing that would be too fast and risk burning my tools, I used two pulleys of unequal size.

Since I planned to make my own pulleys, I just needed to find the right combination that would yield a final output rpm somewhere close to 250. I found an online Pulley and RPM Calculator that was very simple to use.

My final pulley sizes were approximately 1.5” for the primary (drive) pulley and 3.5” for the secondary (driven) pulley. This setup yields a final rpm of approximately 275 rpm, (with my drill press set at 650 rpm).

The exact speed is not critical so long as you are not spinning so fast as to create large amounts of heat. As you can see in the video, I use my fingers to apply the light to moderate pressure on the chisel. I feel a rise in temperature as I am sharpening but it is very minor.

Looks like a pretty slick setup you have! The only thing I was going to suggest is you might want to hone the back only when you are done with the last grit. The bur will come off easily on a high grit and you won’t be introducing new scratch marks each grit and having to remove them each time. Just to give you an idea, I stone sharpen all my tools and if it is just a quick honing I just remove the slight bur with my strop. If I am actually sharpening I just hit the back quick with the last grit. Just thought I would suggest it. Lookin good.

Hey thanks, MNWOODWORKER! I tried that and it worked well. It is important to note that the back of the tool should be flat before sharpening so if you already have a very flat back you can skip that step. If you need to flatten it, go through the grits, flattening the back only, then starting with the low grit again, sharpen the tool. The burr does come off with the high grit but tends to bend over to the front. Just hit the front edge again and check the burr. It works well and is fast.

Thanks again. :)

Great video, and what a fine sharpener. I’ll have to try to find that issue.
It’s also nice to know there are some other HF freaks out there. I guess you go where you gotta go to make things work.
