## Questions & Answers

**Q: Whats the arbor size?**
A: 3/8" arbor

**Q: Can i use the caquxil diamond discs sold by amazon to smooth cut bottles with this machine?**
A: If these discs have a 1/2" arbor hole and weigh less than 2lbs, then yes

**Q: Can you use both sides of backing pads at same time**
A: We do not recommend this, as the backing plate can get off balance.

**Q: Can I use this lap and polisher for pieces of steel, nickel, or other metals?**
A: It's more for lapidary work, drips water onto diamond discs. Try 3M fiber polishing wheels (6" x 1" wide) on a bench grinder. They work great on any metal.
