Thanked: 170You would want the variable speed machine, which lists for over $3000. If you are just restoring razors, there are cheaper options. If you plan on making your own razors from scratch, you may want a belt grinder, like the Wilton. You probably would still want to have a good buffer/polisher as well. Check the library for tools to restore razors. I think there was a post a while back about necessary tool inventory for restoring razors.

Thanked: 170My setup uses a 3 phase 1750rpm motor with a phase converter. I have run it anywhere from 10% (of 1750) to 200%. I don't know what that is is feet per minute. I'm not sure what extras are available for the Wilton. I have 8, 4 and 2 inch wheels and flat platen. The really good guys probably have smaller wheels for working around the tang. American Knifemakers sells a pre-cut kit, and a set of 4 step pulleys would give you all the speeds you would need with a 1.5 to 3 hp motor. KMG and Baldor make a great belt grinders - pricey, but worth it. We ran a workshop here in Minnesota several years ago to make your own grinder - around $650, plus motor and pulleys. Lots of possibilities. Good luck on your journey.

I do not own one, but have used several Wilton grinders. They are industrial well built machines. If you get one that you can vary the speed and get the size contact wheel that you would want it would work great. A Wilton square wheel grinder without variable speed running fast is a metal eating machine not well suited to razors.

You need variable speed for post-H grinding which is the most heat sensitive step.
Without speed control, you'll burn up razors. Also in terms of wheel size, I find that 4" is the size I use most. 8" is something I use occasionally. 12" virtually never. The 12" was included by default.Til shade is gone, til water is gone, Into the shadow with teeth bared, screaming defiance with the last breath.

I know very little about this topic but I do remeber one of the pro razor makers saying he used a 2" wheel for something or other and seemed to think that was interesting to the forum readers. I cannot remember the particulars beyond 2" wheel.
Be careful how you treat people on your way up, you may meet them again on your way back down.

A 2" wheel is useful if you want to hollow grind. The easiest approach is to first grind the razor using a larger wheel, and when the bevels are ok, you switch to the smaller wheel to scoop out more metal from the hollow.

Here is what I am running & you can pick up some wheels from Sunray. All said and done you can get running for about $1,000.
