I picked up my QT12 tumbler yesterday
assembled it about half hour ago and it's currently running. It is super quiet! The drive shaft and follower shafts are each rubber coated, and the barrel is completely rubber. So the only noise you hear is the very muffled brass moving about inside. I could run this thin I. The same room as a sleeping baby I reckon, and that's why I bought it!
Later on I'll pull some covers off the gear drive and motor shaft to see of there's anything you can get ideas from for your DIY tumbler
What is a good and cheap burnishing compound? This stuff feels just like a fine sand... I don't want to be spending a mint on consumables for this process.
Also, anyone got any great DIY separators for the pins and brass?? I'll ask now before rushing out to buy one lol
Cheers
