One of my Christmas presents contained the hubs and pulleys to rebuild my power honer. This is based on the Burke sharpener that is available commercially. It is 15” wide (24” at the top), 11” deep, and 19” at the top of the wheels. I used a 1/2 HP 1725 rpm motor that is reduced to about 300rpm with 6” pulley. The discs are 8” x 1” and two are covered in sandpaper with 120 and 220 grit. The other wheel is covered in leather and used with honing compound and a 6 inch spiral-sewn buffing wheel completes the outfit. I was very pleased with how smoothly the wheels run after truing them up on my disk sander. The sandpaper is a little aggressive at the moment, but should be fine after it wears a bit. Once I have the profile and edge like I want it, I polish the ouside to a mirror finish and remove the wire edge on the inside with the buffing wheel.

It looks like it gets them real sharp like. You must have got your thumb, looking at the last pic! ;)

Nice Mike,none of those high dollar sharpening systems for you. I bet this works just as well as the those expensive models.

No bandaid….wearing my thumbguard even when I test my tools on scrap wood! It does work great, but for me, this is an expensive model! Wouldn’t have been too bad, but I sprung for a better motor!

Sweet job but I think you would have done better to make the wheels at least 1 1/2” wide. Much easier to sharpen on a wider surface! (Not too late!)

Nice job. These power honers seem to be the ticket to easy honing. I’d like to try one some time.

I’m jealous. I need one of those units there. Great design – i really like it. I wonder if one could go with a smaller motor as far as torque necessities are concerned? I suppose with the shaft supported inside those bearing housings and no more than it weighs this is not a big issue.

What is the formula for determing rpms at an individual pulley when working with the pulley size on the motor shaft?

thanks, Chris

My older honer had a wider wheel, so I may make it wider. I chose 1” wide because I could get the abrasive belts in that size and most of my tools are smaller than an inch wide. I used bronze bearings that I already had, but you can get them or ball bearings and all the hardware needed at Old Texas Woodcarvers. I have bought a lot of stuff from these guys. I have used a smaller motor before and 1/2hp is probably a little over-kill. I calculate rpms from the size ratio of the pulleys. The drive pulley on the motor shaft is always going to turn the same speed as the motor, 1725 rpms. I use a 1” pulley on the motor, so a 1” pulley on the main shaft would also turn at 1725. If I make that pulley 2”, the drive wheel has to make 2 revolutions to turn the new pulley one time, effectively reducing the speed in half. I used a 6” pulley on the main shaft, so dividing 1725 by 6, gives a speed of approximately 285 rpms. Close enough for my purposes, since my main goal is simply to get it to turn slower rather reaching a specific number.

You have given me some good ideas. I need to dig through my extra parts pile and see what I can come up with

Thanks
