Well, this is my creation to the tumbling hobby. I searched throughout the web getting ideas for the past 3 weeks and after the first 24 hours of running it seems to be doing well. I attached it to the back wall of my garage and I am getting vibration noise so I'm thinking about getting it on 4 legs with vibration dampeners. I also made a foam box that goes over the barrels so that I cannot hear the tumbling rock noise from the pvc barrel. Currently, I have (1) barrel with Mahogany Obsidian and the other (2) have Wonderstone. The only question that I have right now is.... How does everyone keep themselves from wanting to look inside the barrels everyday? Attachments:

your tumbler is looking good. The only recommendations I can make would be to maybe add rubber hose to the main shafts to avoid any slippage and it might quite it a little too. I got 3/4" I.D. automotive heater hose and that has worked good. The only other thing would be to get a guard over that upper pulley for safety reasons. Nice job and have fun with it!

That's a nice looking homemader you have there, should serve you well for a long time. That's a good idea, slotting the table and putting the motor under.

I looked into putting either rubber hose on the shafts or something on the barrel to keep them from slipping. At this time I have (3) wide rubber bands on the outside of the barrels and I'm not noticing any slippage. I'm not sure what the life expectancy is on the ruubber bands, but I might go with O-rings or rubber hose on the shafts later if this doesn't work. Yes, totally agree with the guards. I plan on making one for the upper pulley wheel and one around the entire motor assembly.

our tumblers are very similar. Both have the motor mounted under the shafts on a hinge plate and both used offset mounting for the pillow block bearings. Ours has been running 24-7 for 10 months now and I have all the parts to add a second set of shafts above the current set and I think I will set those up to run 6 or 12 lb barrels so I have more options. here's ours Chuck

Really nice looking set-ups, both of you. I don't see why you couldn't load the barrels up with a bunch of rubber bands if three does not work out. Great idea. Jim

Probably just making it free standing will take care of any sound transmission through your house and maybe put it on a rubber lined bathroom rug if you still get sound through your floor.

Vibration puts me to sleep. That is why I will die if there is an earth quake. Jim

I was thinking the same thing, Drummond, but how would you hold the pulleys tight between the first and second drive wheels? I understand the motor on hinges to keep the drive pulley tight, but between (2) different barrel shafts will be tricky. I'll have to think about that a little longer. Well, I put the entire table on its own legs and freed it from being attached to my garage wall. The vibration was reduced by at least 50%, but if I want it reduced anymore then I'll have to put rubber under the pillow bearings. I'm very happy with it now so I'm not thinking that I will tinker with it anymore. Attachments:

That came out great. I like the flexibility that seems to give you with the multiple barrels. Nice job! Paul

It does not look like you have the belt on the right side yet that drives the back shaft? I am thinking the belt that drives the upper assembly would really be no different then that one. Might have to put the belt around both pulleys as you slide them over the shafts unless I can come up with a hinge mount for the whole upper shelve to let the whole shelf drop down to change belts then lift it till there's good belt tension and pin it place. looking forward to trying it soon so I'll let ya know what we come up with.

You could add an idler pulley and spring to keep the second belt tight. Jim

Jim,
I thought about the idler pulley and that would work but would be a little more trial and error on the design with belt length and components. I gave a little thought to the idea of suspending the upper shelf on for threaded rods so that it could be adjusted in height easily. Still not sure what method I will go with.

I'm thinking that I'll try reverse hinges on the upper deck and have pins that hold it in place once the belt is tight. I'm going to throw something together on paper and make a material list.
