Putting together a vertical disk grinder...

Robert_Phelps · Oct 3, 2009

I've been wanting one for a while now, and I'm finally going to have some equipment money soon... I saw one at a GA knife maker's guild meeting in Columbus that was water cooled, and I've wanted to get my hands on one ever since

Are there any plans floating around the web somewhere, for sale or for free?

I made mine from a d.c. motor, controler, & disk.
Find something to bolt it down to, and something to mount the contoler to (could be the same thing). Order a disk from Rob Frink. Start ginding.

Alrighty, thanks :thumbup:

I wasn't sure where to get the disk from.

anyone know where to get a motor and controller that will work for this application (variable speed, reversible) that is reasonable priced or even used. I have considered purchasing the grinder from Rob but would really like to save some money if possible.

Thanks

He carries one that is completely flat, and one that has a 1 degree slope to it. I like the one 1 degree so the long blades don't catch the other side of the disk.

...and I like the flat one because you can't flat sand on a cone - even a 1 degree cone.

Rob!

Rob makes a good point. It's not really flat, but since I still hand finish, the hollow grind that that a 1 degree cone makes (about .0087" deep on a 1" wide blade, and .013" deep on a 1-1/2" blade) gets sanded flat in about 1 minute.
Get one of each, and live the good life.
