Thread: Hollow grinder

Very nice... hey charlie, I really like your style...FWIW It'd be cool to spend a day in the shop with you guys that make your own blades...so much talent here on SRP

Cool contraptions - Cool razors. Cool dude

I've put one of my full hollow razors sit in the wheel and I can see a glimpse of light between the middle of the razor and the wheel which means that the wheel doesn't touch the hollow part of the blade.
Red, how come your 8'' wheels are good for you? What would be the ideal diameter for the hollowest grind razors?

Thanks

Leon,

I use the 8" wheels on my homemade razors. I make differnt size contact wheels for my homemade sander to clean up factory made raozrs. I then buff using small buffs that fit inside the curve of the hollow. Here are some pics of my home made contact wheels, they are not much to look at but they work.

I am using a 1725rpm enclosed motor. I bought the step pulley at a surplus store, the big pulley came from the corner hardware store.

You could probably make something from the motor but you would have to protect it from metal dust. Metal dust kills motors. It would be a hobby/putzing around type of thing, but what the hey, that is where the fun is for me.

i see im not the onlyy one that marks the buffs with compound (wait till you makr them also with wood, steel or brass cause of how bad brass and nic silver black a buff

Charlie,
I'm confused. If you use smaller buffs to fit inside the curve of the hollow, doesn't that mean you need a smaller diameter grinding wheel to grind that hollow in the first place?

I use the smaller buffs in conjunction with this homemade grinder. I mainly use it to restore razors. The wooden contact wheels on the grinder serve as my different size wheels. Since I do not have buffs made in the same sizes as my contact wheels I choose the largest buff that will fit inside of the radius.


When I am making my homemade razors I use 8” everything - platen, grinding wheel, and various buffs.

Nice! Clean, simple and effective. Not to throw a wet towel, but I DO hope you let it run for 15 minutes or so after shutting off the drip. If not, you come back an hour later to use it again, the wheel can be badly out of balance. Bad Bad Bad!
That said, I do like it! Thanks for sharing.

You are exactly right, it gets out of balance even after setting still for 10mins. I do the spin dry method.
