Here is (edited: custom designed and built) tumbler that I had. I though it was a Scott Murray as it was green and came with a Scott-Murray 15# barrel, and it had a slave drive setup like Scott-Murray tumblers have. However, as it turns out, it was a one-off designed by a guy on this site that contacted me about it. It is way overbuilt. It is now tumbling rock up in Vancouver, BC. Note the side grill, full size bearings with zerk grease fittings, and roller guides for the barrel. And the feet rubbers. This unit will last forever. This came out of a machine shop in Milwaukie that made beer tap handles. They used it for polishing prototypes. As it turns out, the original design had the slave drive on the main drive side, and not as it is here. Someone that had this unit before me changed that around. Also someone changed the wiring to add a bench mount switch. Also it was designed for a different type of narrower barrel, and these were not designed for it. But they work after I added longer bolts to raise the barrel tender rollers on either end so they do not snag the wing nuts.

Here is a medium size 15# Scott Murray tumbler that I also have. The original small motor burned out on me last year so I replaced it with a Taco pump motor on an adjustable wood plate so I can adjust it as the belt expands. I also added the power switch. This rides smooth and easy on raised pillow bushings. I replaced the roller sleeves with electric grey PVC, but they were a pain to pound onto the rollers.

So I have come across several Scott Murray tumblers that I have picked up in the past few years now. Also what I thought were Scott-Murray tumblers that were actually custom built tumblers. I really like them as a group. They all seem to have slave driven pulleys and belts to drive the second roller, which is a real advantage over Lortone and Thumler's.
Here is the smaller Scott-Murray tumbler that I have now. I lifted this photo off this forum for ease of posting, but mine is exactly the same. I use a Lortone QT12 barrel on mine. I am missing one bushing that I am looking to replace on one of the roller ends. Note: Rochpickerforever is looking up the bushing number and where it can be gotten from. (update: I found them listed at Zoro that were the right size but a tad long, so I trimmed them and they work great). This tumbler is back in action again. Well, its twin is back in action.
FYI: This is a Scott-Murray Hy-Pol Model KCB-10 Rock Polisher Tumbler

I never really got the appeal of Colla Wood. Sure, it's gorgeous, but way overpriced. ($3000 for about 3.6 kg? $833/kg? I'll stick to my nice, cheap, Pietersite! ) Yeah, at $380 a pound, that is steep. Makes my lapis collection seem like bargain basement deal!

Sure thing. Just 50% vig (interest) and you put up collateral, like the pink slip to your car or a second mortgage on your house. Guido and Sal will be stopping by with all the papers and the loan money.

So I have my DIY Richardson dry sander/shop vac lap tool built and working now. It works great! I have a pile of 7" #80 and #120 discs for it (SiC). I need some SiC #220 and #600 7" discs for finer sanding. Anyone know of a good place to get cloth backed sanding discs? Richardson wants a buck a shot, but GranQuartz has #220 discs for $23.50 for a pack of 50, plus shipping. They do not have #600 listed in stock. Amazon is all over the map, and I cannot find a good deal on discs there. Not saying that they are not there, I just cannot find the finer grit discs on Amazon. I found some #120 on Amazon ($24 for 50), but I do not need that. I found some #320 on Ebay, but I do not need that either.

Here is my more or less finished DYI dry lap sander with side vacuum attachment. It works pretty well.

A buddy and I always hit the gold sheen obsidian claim... We get permission every year to dig there.. I usually surface hound the area.. Some people dig up the Obsidian and just toss it to the side, I get some sweet material that way! I don't know what they think they are looking for, but that's ok with me....Hahahahaha Beats digging... Sweet material you cut there, totally awesome!!
True story: when my brother and I were at Glass Buttes about 3 years ago we were on the side of the main road going into there looking for float. Along came an SUV with a couple in it, and they stopped and showed me a nice polished piece of mahogany flame made into jewelry. Then they asked me where they could find it. So I looked down, and lo, there was a nice piece of mahogany right there in the road. So I picked it up and handed it to them as said, "You are driving on it." They seemed stumped with that and rolled on down the road.
There is a lot of gold sheen float at most sites at Glass Buttes, but people do not know what it is when they see it. The rock I cut above in the photo was a dusty old crappy looking rock that I got at the cattle pond next to the road. Even I was not sure it was sheen until I cut it up. I just randomly picked it out of a bucket of obsidian to dress my new saw blade as it was a good size for it. You have to cut it right to get the sheen though.
Today I found some nice aurora, electric blue and rainbow obsidian at a sale that Rockoonz (Lee #2) here put together. That and a bucket of Hampton Butte wood followed me home today. I love hounding through giant piles of old material.

While I know it is great adult fun to joke about drug induced visions, I feel I should remind everyone that is supposed to be a family friendly forum. Please don't post personal things about drug use. edit- I you feel you must, please take it to the Cave. I deleted any reference to alcohol in my recent posts and just to be clear, I don't share my drinks with anyone......... johnw Well, this is a PG-13 rated family forum, not G rated. Says so in the rulz section. So I will leave my posts as they are.

I am not sure how I will use the flat lap yet. I just finished up the dry sander and I will see what I can do with that first. I have a line on some cheap slightly used carbide floor sanding disks which is what flat lap pads take. I also have 2 dual wheel cabs machines, as well as a buffer. So I may not even need a flat lap machine. But if the dry sander does not do what I want, then I will start building the hydro flat lap. I am looking for more parts for it now. I need the right size pan for the drip pool, an old desk, some type of bearing system, and the flat spinning top. Or as you said before: I have an engine and tranny, but no drive gear, no body, and no interior.

my 36 inch flat lap is 30 rpm. if you are going to use grit on yours, I would think you are too fast. if you are going to use a small diamond plate like the amerteck ones you should be good. forum.rocktumblinghobby.com/thread/78673/36-inch-flap-lap check out the link to mine. good luck, let us know how it works with pictures. I never could type worth a hoot!! Your flat lap is completely different than what I am planning. Much smaller diameter wheel, no sweeper or any of that stuff. Simple design... here is a desktop design that is more along the lines of what I am designing (photo 'lifted' off this forum). But mine will have the pan flush with the desktop and the motor will drive a pulley, and it will have a drip water supply and drain. I can get a 3 tier pulley for the motor and a larger driven pulley to be variable speed and go slower. I have to figure out a bearing shaft wheel drive system as the one in the compressor that I am cannibalizing for this project will not work. I may use a squirrel cage fan motor with a pulley system already set up instead of the compressor motor.

I hope you are going to sue something to reduce the speed. too fast and grit and water will just be slung off. Slower the better. My lawyer is too expensive to sue anything
The motor I have for it is 1725 RPM. It is set up to drive a compressor with a v-belt with a 1:3 pulley ratio on it, which reduces the spin to 575 RPM. I have a smaller drive pulley that I could swap in to cut that in half to about 290 RPM. Slow enough?

I mean to mount the motor vertically in the flat lap, and the spinning disk would be horizontal with a water drip line.

I think that the reason the Richardsons sanders are made the way they are is the intended use and safety. Since Thunder eggs is their primary business cupping an egg half in your hands is ideal. You can see your progress without your eyes being in a place that a shredding sandpaper sheet is likely to go. If you're holding the piece with gravity keeping it in your hands your fingers are less likely to stray past the surface and get sanded or sliced with the edge of the sanding disc. Vertical disc sanders used for wood or metal typically have a scatter guard and a 90 degree rest due to the safety issues. If your motor has sealed ball bearings, as opposed to sleeve bearings and oiling locations, it makes no difference what your shaft direction is. I have seen home made sanders with a pivot point so they can run horizontal, vertical, and anywhere between. I wouldn't mind having one just to do eggs on, but I really don't need one since I have the flat lap and bull wheel. If I had one , it would only be used for eggs and egg sized chunks never slabs. I have a few eggs here to grind and polish. Most of my stuff to polish using this machine is petrified wood and jasper, which are large pieces with flat or slant cuts, or end cuts. I also have some Biggs that I want to polish in their natural shape. I have no intention of dry sanding thin slabs, as they would get hot fast and are hard to hold. I want to make a wet flat lap with another motor that I have. That will be vertical mounted in a small desk with a water supply.

I have seen home made sanders with a pivot point so they can run horizontal, vertical, and anywhere between. My design has a guard boxed in on the plane of the sanding disk and about a 2 inch overhang. It is not open like the Richardson design, or like the photo I posted above. My design looks like a baby cradle, after finishing the wood frame today. Or one of those old gold rockers. I will post a photo when it is done.

Well, rather than abstract dogs seen in stones, I can clearly see a very cool dog in this one...
It was posted here, "what do you see in a stone?" can be interpreted as asking, "what do I see when smoking Maui Waui", yes? A different kind of stone, as it were. Since we are abstracting here and all. This is more what I see in a stone. I believe I lifted this photo from this forum some years ago. Very original photo. I see it and I want to be there. I want to crank up Steppenwolf's, Born to be Wild and see what is in a stone... A Maui Waui stone.
