That's great.. I would love a drum ... There is a place about 10 miles from me that sells unlined drums... Looks like i would get off my backside and at a bare minimum... Build me a uds..... I may be getting lazy.... .... Thought on my new smaller unit i am designing to incorporate a drum into the build... I am afraid this small unit i am thinking of... Is getting bigger and bigger .... It is a sickness... I just cant help it... My buddy told me i would have to build 3 or 4 before i was happy... I thought he was crazy... But i think he is more sane than me... Lol.....
