nice ones, hard to pick just one. Are we supposed to vote for the 'best polish' or just the 'best overall stone'?

Great egg,waterlines are perfect and the white and blues really "Pop"! Blue bed egg,is it?? yes I'm pretty sure. Always hard to pass up a visit to the blue bed when we're there.

Awesome egg...curious, which part of Cali is missing? Cheers I think you can see the San Andreas and the part that will slide off into the ocean during the big one...

The nay sayers on man made global warming (still pretty much on the fence) have not seen the amount of pollution a country like China pumps into the air. If it is not warming the planet it is killing a lot of people sooner than normal. Yeah, I think it is also hard to comprehend because a lot of the pollutants are gases and not visible to the human eye. Average tank of gas is ~100 lbs, that in turn produces about 300lbs of CO2. Imagine if it was like horse poop - how deep the streets would be. Scaled volumes of the planet's water and air... Must be a lot of rocks out there! ![](http://www.sciencealert.com/images/stories/earth-water-air.jpg)

I have the exact same unit (3barrel) they are 12lb barrels. Are your units for sale? Sorry, they've both found new homes... My son had fun in metal shop for a replacement. Found a nice 1/12 hp motor draws less than 2A with two full barrels and is barely warm to the touch.

Thanks, have to post a pic in return, not sure what this is, collected locally(Western Oregon), usually mostly Agate Jasper on the hill there, Looks like a lower quality Jasper maybe? Pretty banding, barely fit in the saw, have to take a hunk off the back to see... ![](http://i1074.photobucket.com/albums/w418/korimako/jasper.jpg)

Here's one of my favorites you don't see too often... Used to survey for herps at the park down the road, photos over here if you want to see a few of Western Oregon's snakes & herps. ![](https://lh4.googleusercontent.com/-aCIUnJ7Udmg/TdstNMqd16I/AAAAAAAAAok/LGwkaBk57gUH6W0kl_WACd85_oLzFQWQQCL0B/w712-h534-no/P1070061.JPG)

Keep meaning to really give this a try, but was cleaning up today and threw one of these garden sprayers on this tumbler frame. 1 gallon seems to be just the proper size. The sprayers are cheap, but thick-walled to hold the pressure, shouldn't be hard to plug the small hole and seal the large one. (Anyone in oregon looking for a single (scott murray) or triple frame, drop me a line)

I found these. They are good Bodine motors. Continuous duty. I realize they are running at 743 RPM. I figured that the money I saved buy buying three of these at only $39.95 can be used to purchase the 3 pair of 1 to 7 ratio pulleys, shafts and bearings I will need to get things on the grinding heads to around 100 rpm and still have enough money to finish the machine according to my design for way less than $300.00. I plan on making powder coated sheet metal drip guards for the motors due to their open design. I already have the sheet metal and powder coat machine. I have some heavy gauge sheet metal to make the grinding cup and motor mounts that mount on the hinges. I just need the base (probably 80/20), hinges, and grinding cup set ups. I have tons of stainless cap screw bolts and other hardware I will need. I added up everything I need to buy to make the machine a reality and the grand total (not including the grinding cup set up) was $282.83 ![:D](//storage.proboards.com/forum/images/smiley/grin.png) Chump change as far as sphere making machines go. I hope my dream becomes a reality sometime later this year. at 36 lbs each and 10 Amps per motor, that'll be one serious sphere machine. Might want to plan on a 30-40A circuit somewhere for that.

You just need a long lasting connection between the moving and non moving parts right? The lotto uses spring steel, the other vibes seem to use coil springs. The rubber bushings should do, but I think these isolators are used in scenarios where rubber mounts are not up snuff. I've also seen this type of wire isolator used to mount cameras to vibrating objects. Stiff but flexible I guess. Maybe the front of the frame only has to be on a pivoting axle? Certainly plenty of experiments to be done. Not a MEch E here, just tossing out an idea.

Trucks certainly should be fine and inexpensive. Another option might be making cable isolators if you have some spare wire cable around. Not sure why they seem to be a preferred choice in high tech environs, or why they're so expensive, but always look intriguing when I come across them and shouldn't be hard to make something similar. ![](http://www.vibrodynamics.com/images/wri/cable.jpg)

Do you have an equivalent closeup for the minisonic?
Agreed, hard to judge from the screen, trust your in person comparison better.
Curious, can you compare the time to tumble, and maybe the current draw of the three machines? All look to be 4 lb'rs..

Actually - what kind of plug do you have in the other end, or do you unscrew the entire plate each time? oregon , this is the bottom of one of my 5 gallon barrels. I've built over 20 barrels of this style and in various sizes, none have failed. If there is an interest, I will put up a detailed construction procedure. ![](https://c2.staticflickr.com/2/1658/26262109090_8ebbfbee77_z.jpg)

I did contact MLS - They knew less than I did about this tumbler! Honestly, I don't think they knew it existed. New owners since those days I imagine. Vacuum shop had a wall of belts but nothing looked suitable, so I put a proper timing belt gears/belt out of my 'stash' on it and see if it'll turn a 12 lb barrel at not to fast of a speed.

no need on my account, looks like careful drilling & cutting, with a rubber seal in between? hmm, might have to pick up a couple sections... Thanks.

Anyone know anything about a MLS-12 tumbler - picked one up missing a belt, it's a fine toothed belt... but to my suprise, I don't see anything about a line of MLS tumblers that google can discover. Has two six lb barrels, sorta gray, but built like a lortone. have to get a picture later. Thanks.

So, different as in different shapes you like to use, or just free forming with the rock in front of you, no template involved? The symmetrical shapes don't change character much when you change proportions, but the non symmetrical ones (upper right - 3 pointy Sail thing) tend to look very different when the proportions change unequally. I just draw one shape (bezier curves can smooth out most complicated shapes) then instead of printing a single version, it spits out a grid of differently proportioned ones. Just tinkering around...

I'll be making end caps, couldn't imagine cost of 10" ones, easy to do. Just re browsing... Is there a cheaper way to seal the ends on large PVC? , or how do you plan on rolling your own? Local surplus has plenty of large PVC fittings, but purchasing suitable endcaps for barrels etc adds up quickly. Thanks
