Glad it looks good. Never heard of an 8 lb either but you can build what you want................MrP Thanks fantastic5(Ann), MrP and all you others that prompted me. Ann, thanks for the tip on the ad. New husband put it out on the front door step with the ex Or should we say that she put the ex out on the front doorstep? Either way, I paid and ran. Tumbler looks extra-terrestrial.

that machine founds it way into the right hands. Looking forward to some shiny results (no sugar required). Chuck You may have to pry the sugar away, don39 is using it in his Viking.

Laurie texted me this evening thanking me for sending you her way. Said she must have underpriced it because you didn't hesitate with the purchase. Glad you got it! It was a bargain. Would have felt guilty negotiating, looked like it was in fine shape. Perhaps the fact that it was the ex husbands..... It is built with an unusual concept. It is the first vib I have ever seen that could possibly be home built. Not sure, but a possibility. MrP put an LP tank on it, it runs different size hoppers, making it a bit universal. Most vibe are tuned to one tight weight band, one size hopper, this one is different. It does require a $319 double shafted motor. That would be something to redo so that it could run on any single shafted cheap motor. It is expensively built, not just the materials but the technology was a probably a big investment. But just speculating. Instead of the eccentrics being connected to the motor, they are mounted on a shaft w/heavy pillar blocks. So the force of the off balance motion is transmitted to the large pillar block bearings instead of the small motor bearings-ingenious. i.e., isolating the motor

GyRoc does something similar with their belt driven vibes. Counter weights attach to bowl drive shaft instead of motor shaft (as typical with most vibes (Raytech, Thumlers, etc.). Motor runs more balanced which is always a good thing.

Glad it looks good. Never heard of an 8 lb either but you can build what you want................MrP Thinking about an 18 inch length of 6 inch sch 40 PVC pipe with end caps MrP. And a 4 inch tee opening for a rock portal. To have a plastic barrel. And save moving weight. Using a U-bolt on saddle fitting. And weld a plate to the bottom of the U-clamps to serve as a bracket to mount to the Viking receiver. Or add additional saddle clamps for base connection. Use plumbing rubber end cap to 4 inch portal off. Checkout saddle: Or use a 6 inch tee and end caps. Nice pipe clamps available:

James
That looks like it could work. You just have to make sure it is held solid. I had the nuts holding the tub on work loose and break a hold down bolt. The base bolts have to be grade 8 and very tight. I should say they didn't come loose until I went to the bigger tub. Only happened once but that was enough too make sure it is tight every time now. I ended up using new lock washer more often and a longer wrench just to make sure the tub is on tight. There is a lot of force involved in shaking that much weight in that manner.
When I bought mine it had four 6 lb tubs with 2 of them having a hold down ear broken off. I couldn't figure out why that was until my big tub came loose.
As a side note; I am sure you know that in a lot of applications a lock washer is a one time use item. Once you compress it and release it they say it is never the same. Bolts also in some cases, because of the stretch. I always thought it was to sell more.
Snowdog you ever have one come loose on you?.................MrP

I sure wish those prices were still the same. A person could buy one of each part and build it for cheap.............MrP

Grade 8 bolts are for demanding situations, and after torque ing one that hard the lock washer is probably done. Puzzles me they use 2 bolt mounting instead of 4. Makes sense that the hold down ear broke.

Watching this thread closely!! connrock Humbled by obsidian, forced to go vibratory. Not give up on the rotary tests. Still at it.

jamesp....thanks for posting the Viking manual...lots of valuable info there There is a lot of info Mike. Looks like the Viking will get used for polishing the rocks from the rotary tumblers. Hope to get the rocks to pre-polish in the rotaries, and final polish in vib.

iant....I use Apache Tears as filler when I am tumble finishing cabs or beads. I have two 5 gal. buckets of rough tumbled Tears and they have come in handy when I needed to fill out a tumble load. They also finished extremely well. jamesp.....precisely the thought I have and what Tony suggests as well....do the initial work in the rotaries and finish them in the Vikings.
Given the discussion and barrel design and fabrication in this thread I am now entertaining the thought of making a scaled up version of this type of machine. A moderately scaled up version; not a large or giant version.

A moderately scaled up version; not a large or giant version. Initial thoughts were this machine can be reproduced. First vibe I have ever thought such. The fact that different weight barrels can be put on it tells a lot about it's versatility. And it does not put the counterweight on the motor-yes. I get crushed glass from Strategic Materials and find it to be a great filler for most rocks. $70/ton, and they have many operations in the US. Based in California I believe.

Do you use the glass for tumbles other than obsidian? You use it in all tumbles instead of ceramic filler? I have a Strategic Materials down in Sarasota (an hour south of here) - what specifically do you buy? And, do they sell by less than a ton? Pretty sure the wife would frown if I brought a ton of crushed glass home. How big a pile (cubic yards) is a ton of glass?

Sounds to me like some self locking nuts (also single use item) or make a man out of them and double nut them. Anything that starts coming loose on me gets an extra nut. Works every time. Jim
