Many years ago, when I first got into tumbling, my first rotary tumbler was not one like we all have today, i.e. sealed barrels running horizontal. I am hoping I can describe it adequately. This one had a rubber hexagonal barrel that tapered at the top and was attached to a flat platen. Out of the bottom of the platen was a metal rod. The barrel did not have a lid. That was the barrel assembly. The base was constructed in such a way that the motor was perpendicular to the barrel assy instead of parallel as our lortines and thumlers. The rod of the barrel assy slid into a couple of round keepers at a 45% angle and the motor pulley was set up to a small wheel that contacted the bottom of the platen on the barrel assy which made it turn. It worked pretty well and the advantage I can see in it now is that if you are trying to tumble material that off gasses, there wouldn't be the problem of the barrel bulging and/or popping the lid.
Has anyone ever seen something like this? I have tried to 'google' a 45% open top tumbler, but no results.
I sure wish I could find one of these again. A few years ago the landscapers where I lived must have figured that the barrel assy I left outside on my porch was trash. I think it would be great for tumbling a ton of Glass Butte obsidian that I have, because right now no matter how much baking soda I put into my thumler barrel, it pops after just a few hours. And once that happens, I do not know about you, but the only way I can get a new seal is to dump the whole thing (wasting all my hardly used grit), cleaning thoroughly, and trying again; only to waste more grit within an hour or so. Grr.
Thanks in advance for anyone who may understand the type of rotary tumbler I have described and even more thanks if you can tell me where to find another.
