Good Morning,

I’ve got a Ridgid EB4424 Oscillating belt and spindle sander. It uses 4” x 24” belts.

I’ve got an idea to use this for sharpening my gouges, chisels, and planes. For my gouges, I’m planning to fasten piece of wood, with a V-groove, to the miter guage and use that to hold the gouge at the proper angle while I rotate it on the belt. The same concept can be applied to other tools too.

I found a source for high grit belts at http://www.supergrit.com. They sell Black S.C. 4×24” belts up to 600 grit. I’m thinking that this might be perfect.

The minimum order from Supergrit.com is $25 so I wanted to get your opinions before pulling the trigger..

Regards,
Rick

I’m not sure, but I know one of the key issues with sharpening is that you need relatively slow speeds so that you don’t build up enough heat to ruin the temper of the steel. I’m afraid the belt sander might be too fast, but I will be anxious to hear what the sharpening experts here have to say.

Hi a belt sander is just fine so long as you pay attention to what Charlie said and keep the tool moving and relax with not too much pressure to avoid heat build up but this is so with any sharpening tool.I see more and more people recommending belt snaders why I think robert sorby sell suchh a device if I’m not mistaken. good luck you’ll get a great finish with this keep it moving the tool that is fix the belt sander or disk sander it matters not.Alistair

Stones, wet stones will give you a better edge. Sanding is a much more expensive way to go. Good luck!

Why do you consider sanding more expensive?

Why do you consider sanding more expensive?

Because you have to buy a consumables over the coarse of a lifetime. They wear out after a few uses and you need to swap them.

If you glue them down to the glass you can’t let them sit too long or its a huge pain to remove it. So if you want to avoid that you end up throwing it a way early.

You also have the pain of tracking the inventory of the grits under use and can run out of them causing a delay.

A basic set of oil stones with a nice Hard Arkansas as the finishing stone puts on a great edge and is a one time cost. I got mine for about 100 bucks

Have your say...
