## Questions & Answers

**Q: My only question/concern is do these two barrels rub against each other or are there spacers so that they spin independently and without friction.**
A: There is no spacer.  They do not rub against each other because they rotate at the same speed.

**Q: Can I buy just the machine. I have 2 spare barrels**
A: just buy the whole machine. The extra barrels may be an asset.

**Q: Does this tumbler come with the grit needed to tumble?**
A: No

**Q: How much course grit do i use for 9 lbs of rocks?**
A: In general you will use 2-3 tablespoons of 60/80 grit in each barrel ( 2 barrels for this model A-R2 ).  That is the first stage for ~2 weeks.  So for 9 lbs ( 3 barrels worth ) you will use 6-9 tablespoons.  You'll want to do some research ( youtube is helpful ) on how to load the barrels as going just by weight won't be completely accurate.
