I used to have my bench attached to the wall of my old garage to make it more sturdy. We moved it to the new home and I have never attached it to anything. It is free standing and honestly this beast I can barely even shove if I want. It does not need to be attached to anything.
I never removed the vise but the grinder and buffing station were removed. I set the grinder on the "came with the house" wall attached bench but the buffing station I have just mounted in fear.
I expected lots of vibration. NOPE, not on this bench. The small buffer can rock out just on a sitting bench, if the bench is like mine, way over built.
My main buffing machine I have not even gotten set up yet. It's a big boy and will need some doing to get it going.
I bought a converter when I set it up in my old house. It is a three phase design, but I bought an adapter to convert it to use two phase wiring so I could use it in a home environment.
I just need to go into my electric box and bring out some 220v to the shop. No big deal, but to do it right according to Code, I have to have an electrician do this. I'm an electrician, but unlicensed, so I really can't do this (even though I can) without concerns with the insurance companies.
I plan to do the work and have a licensed electrician inspect and sign off. I will build my circuit to exceed Codes!
