Questions on Polisher Set Up
« on: December 29, 2019, 09:24:28 PM »

Sometimes you are so lost you don't even know how to phrase the question. I need some recommendations . The club has rented a basement at a community hall for a shop and I'm setting up it up. Others help but I guess I'm leading. My wife is the rockhound, I'm not. But I am a retired millwright and machinery set up is what I did.

For now, I'm setting up six arbors. Five are 6" Loratone doubles and one 6" Mercury triple. The Loratones were set up with a 100grit diamond wheel, an expando , and  6" disc on the diamond wheel end. The 6" Mercury had a 220 grinding stone as well. My wife has suggested setting it up so you don't have to change belts. Do they have diamond belts ? What about the discs ? THX

You can buy neoprene backed diamond belts cheap from Han's lapidary.  In my experience they outlast far more expensive belts with cloth backing.  They are also stiff enough to put a 3" belt on a 2" wheel.  I set up my shop with an 80-100 sintered wheel then a 400 plated wheel.  After that are three more arbors with progressively finer diamond belts running from 100 to 15,000 grit.  That eliminates belt changing entirely.

For the end of the arbor you can usually use sin ons. 1200 grit pad without rubber backing is a very efficient use of one end. After the pad is broken in it does wonders getting a prepolish on problem stone. One grit coarse if you have a second spin on placement. Spritz bottle is all the water you need.
