Thread: 8 vs 6 inch bench grinder

Any major disadvantage to going 6 inch for basic restore work?

anybody? I also am wondering if you can use 8 inch buffing wheels on 6 inch grinder?

What are you trying to do?

Clean up old blades and polish scales.......

I use a 6 inch for my own personal use, I'm not a pro restorer, and I don't do it for money. I have a Delta adjustable 6inch. It goes down to 1700rpms, give or take...

What you don't see is that I recently took all the the guards off, so it's just "Wheel"....

Just for me and the occasional razor, it's great. Now, if there was an 8 inch model, when I bought this, I would have grabbed it...
bigger is always better IMHO when it comes to buffers...

As far as using 8inch wheels on a 6inch buffer/grinder, I'd say no, but I'm not sure. I never tried it. You'd have to take all the guards off like I did, and if it fits on there, why not...

To me, the biggest problem with the grinders is that they don't give you enough room to work on the razor. The buffers on the other hand have longer arbors and you can get extensions which really helps out. I drop down to 6 and 4 inch wheels on my 3600 rpm and that still is pretty fast. 1800 rpms or less is a good speed for beginners and you still have to be very careful.

Have fun,
