[QUOTE="bend, post: 551053, member: 4811"] Couldn't tell you to be honest, I've put about half a ton of 1/2 inch minus through mine so far and other than stripping paint it looks okay. I had considered upgrading the drum but figured i might as well get my moneys worth out of this one first. I have heard of people lining the drum so as to have a replaceable wear surface too. You'll find the gold gets harder to recover if you run it too long, starts to roll up into tiny little ball bearings. Definitely worth sourcing a compressor tank over an old gas bottle, as OldGT said a gas bottle needs to be thoroughly purged. You need to essentially push out and replace 100% of the contents with an inert compound, water and co2/exhaust are old favourites. Not technically difficult, but you want to be bloody sure, and steaming won't do the job. [/QUOTE]
