I have a dedicated grinder with dual wheels, one coarse and one fine. I don't do a lot of grinding. It's mostly for sharpening and dressing tools. I only bring it out from the cupboard when I need it and clamp it to the bench. For buffing and polishing you don't need a mount and shield. For that I use an electric motor which I think once belonged to a washing machine. It was cheap when I picked it up at the swap meet and has given me fifty years of trouble-free service. It's permanently mounted and I use it frequently, mostly for cleaning up rusty parts, buffing keytops, etc. It's quite adaptable with a variety of wheels .
When you look around your shop and ask yourself what else you need don't forget the corollary: how much bench space am I sacrificing to have this?

Scott,
Variable speed Is good. I wish I had a VS grinder. However two dedicated units can prove to be very handy. On my other one I have a deburring wheel which gets used for metal polishing and surface removal. Puts a really nice bright finish on screw heads, nearly indistinguishable from plated. With pressure it will remove some metal. This little unit gets used a lot. Would because pain to switch out the grinding wheel every time I wanted to do a quick polish.
My money would be on a second unit.

Parker,
Thanks, that will also eventually be a topic, along with drill presses, table saws, etc.
And yes, bench building will come first. However, my first question remains: one grinder doing double duty, or two?
Sorry about the photo--not sure why it uploaded and turned it.

Next tool would be a good bandsaw. Rikon has a nice 10 or if you have space and budget a good 14 ". Don't forget a good workbench.

Hi all,
The Journal is planning a series on the basics of setting up a shop. I'm hoping to get input from a wide variety of techs, as I'm sure everyone's shop looks a little different. Stay tuned.
I'd like to address one question for myself, and I'm sure others will have the same question: have you been able to get by with one machine doing both grinding and buffing? I have a tiny shop, about 9x10', so I have limited room for power tools.
Currently, I have an 8", variable speed grinder, and I've replaced one grinding wheel with a buffing wheel. My primary tasks are buffing ivory keys and tool mods.
Have you been able to get by with one machine, or is it a better idea to have two dedicated ones?
do you prefer one size over another-6" vs 8"? I assume a variable speed unit is preferred, at least for buffing ivory.
thanks!
