Thread: small contact wheels

I played around with the 1" contact wheel this morning, I like the hollow it makes it under the spine. I have been using a 2" or 4" wheel for this part of the grind. I used a 2" and a 1" on the razor in the picture.

I have always admired Butch's and Bob Allman's hollow grinding - they inspire me.

I love your double wheel set-up. It's definitely what I want to build (or buy from you) when I grow up!

I'm confused where the 1" and 2" wheels were used though. Did you use them on opposite sides of the blade?

I do not use the double wheel grinder very often, it is a good roughing tool, but a poor finishing tool.

I ground the same on both sides of the razor. I started the at the edge with a 2" them mad a sieres of grooves working my way back to the spine. Then blend the grooves together to make a flat surface.

Here is my CAD drawing (Charlie assisted doodle)

Thanks, that clears it up. I couldn't see a belly or any way to see the two different wheels' concavities. I had no idea anyone "blended" the way you described. (By the way, your CAD is the only way I can do it!) What is your rationale for not leaving a belly?

No real rationale, it is just the cool factor. It is an entertaining and challanging to make the grind that way.

There is definitely a cool factor. If I were to ever do this, I'd fully expect to grind holes all the way through quite a few razors.
Nice job!

Maybe I can talk Randy into a Texas road trip some time!

Great looking grind Charlie!
I've played with a similar set up but tend to alu-foil it about at 1/4'ish from the edge.
Ah...one day I'll make it work.
