Accelerating rust using diluted Muriatic. From no rust to this in 8 hours. Just poured Muriatc on this one, ready to be spread with broom. are you clear coating or anything after? probably not wit the heat. do you use use ammonia or something similar to neutralize the acid after?

right now I just take the grinder outside and dry. I have to make the shrouds yet. made the catch pan base plate or whatever you want to call it a month or 2 ago. just pushed on back burner so I use it dry for now. the rose quarts didn't realy seem to grind any faster at least that I noticed. not surprising its a mohs 7. the rose quartz I bought at a show, the small whiteish one I got off of you. the rest were from a box of bigger stuff I bought off fish. no idea what the material of the top 2 are but they undercut in the tumbler pretty bad.

they range in size from about 2.25 to 1.75 about as big a cube as I could cut with my cheapie tile saw. I rough ground them on a bench grinder with stacked diamond blades. then spent a week or so in rotary a week in vibe. 2 of them came out of polish last week and the other 7 Thursday

if your pipe was a little taller I would say maybe a water soaked sponge wedged in it. not actually touching buy just high enough to keep it from hopping.

what if you shortened the pipe and just used the palm of your hand to roll rock randomly? ill probably attempt something like this soon as my near sheres aren't really all that round. I just been busy with work and getting some stuff done for my blacksmith meeting this sunday. I want you to walk away from it notjust. Let it do it's thing whilst you are watching TV. Ideas ? something with springy down face. Hand would work, but it makes you work it. I am not sure how near to nearsphere the rock needs to be. Sure would be nice if it would work on a less round stone like they are in the real world. I don't know anything with any amount of down force might inhibit it from rolling in a random pattern.

I have a few I freehanded on the stacked blade grinder in the tumbler right now. What type of rock ? I don't know rock lol. not granite lol.

Here's another video by the guy who did video #3. He has a bunch of methods shown for making wooden spheres on his YouTube channel. This method is like the video #4 method. I might go try the band saw method with my trim saw though. Oh yea, not one dang reason why this won't work with a rock. And it really does not matter what type of cutter you have under the hole. Rotating(stiff) saw blade, core drill, shaper bit, diamond cup, tuck wheel - whatever. Looking at the hole size.... notjustone , note this guy never changed the height of his socket. If the hole is 1/3 the diameter of the sphere... the sphere will not sink into the hole near as fast as material is removed. If the hole is say 3/4 the diameter of the sphere then the sphere is going to drop into the hole much more as material is removed. So the relationship between the hole size and the sphere will have a big effect on the process. In you video Rob it looks like the hole size is about 60% of the finished sphere size. I must say, that is a similar process that worked well on the unakite spheres. But I skipped the cube and freehanded the near sphere shape because the pebbles you sent were close to round. Again, the Great Lakes cobbles are often close to round. You are fortunate if you decided to make spheres. There is a massive river flowing into the Pacific at the boundary of Costa Rica and Panama near San Isidros Costa Rica. It too has round boulders to 8 feet for some reason. The Native people even made their own spheres to mimic the river boulders. Scientists to this day have no idea how they got them so accurate. yes-cool-dude.blogspot.com/2014/04/mystery-of-round-rocks-in-costa-rica.htmlyep smaller size sure looks like it keeps it from dropping into socket as much. its hard to see but I think he raised the bit. in the beginning of video you can hardly see the bit down in the hole. look at where the cube is making contact with the socket on the edges of the cube. notice its hitting the same edges for several passes and they aren't getting reduced so bit must be coming up. its a router table he can move that bit up or down from underneath. still can be done but your fixture would have to go up or down since most tile saws have no up and down adjustment on the blade.

or you could go 1 step farther and just buy the spheres someone else made. if you just want a couple spheres to have around the house that would be the cheapest route. but then you wouldn't be able to say you did it. believe it or not for a lot of people here its just a hobby we will never even make our investment back on. I believe it! I live it! well then your hobby budget is much larger than mine. lol. I find it interesting to find ways to do things thinking outside the box.

I got my bead idea from a woodworking video. I made plywood laps for my flat lap using the same method on my table saw. I just went searching for ideas on YouTube. I swear I once saw a video of making a sphere on a table saw. I think the saw had a board above it with a hole in the board. The wooden cube was inserted into the hole and moved around so that all the parts that could reach the blade were removed. The finished ball will not fit through the hole, but will set in the hole with the bottom just touching the blade. Does that make sense. I haven't been able to find the video yet. very similar to the 3rd video where you see him using the band saw to rough it out he never has to adjust his socket. notice as he knocks off his corners of the cube theres no precision at all. cause he knows as hes roughing it he just keeps knocking off the high spots but distance to blade never changes. even as ball gets smaller and drops farther and farther into the socket.

Or you could get the proper Machine and not think about it at all. or you could go 1 step farther and just buy the spheres someone else made. if you just want a couple spheres to have around the house that would be the cheapest route. but then you wouldn't be able to say you did it. believe it or not for a lot of people here its just a hobby we will never even make our investment back on.

The belt sander method is seriously flawed. I've been thinking about this and it can't work the way I'd like it to work. My calculation was for a finished sphere. Those dimensions should work for a sphere. If you put a finished sphere over the hole, it should reach the saw blade (or belt sander). However, an unfinished sphere is larger and will not reach the blade. You'd have to start with a much larger hole and gradually decrease the diameter. The question is ,how do you know what to start decreasing the diameter? I'm not sure this is possible. There may be a very good reason that you never read anything about creating spheres this way. It is an iteration type process. Best if you had the socket on screw that could be lowered incrementally. I feel my crude spheres could have been dialed to a very accurate radius if I had a smooth plastic socket with a simple height adjustment. All you need is a fixed distance for the final grind. I would not change the hole, I would reduce the height gradually. pauls had his sphere within .002 inches using a divot in a board. I feel very confident this will work. you would have to raise height as you progress because as the sphere gets smaller it would drop farther in the socket which would make it cut deeper on its own,
