I'm pretty sure I'm the only one that deserves any backlash from this, but it's nice to know where you stand! And I also already said I regretted saying the thing that ticked the guy off. Was a bad choice of words.
Eric......Don't beat yourself up to much (I know you're not).....lol
A slip of the tongue was not the real issue here. Yes, the comment lit a fuse, thus the reporting......but, in my opinion after having communicated with the OP via PM, he was looking for solutions to a curiosity he had related to a bigger project he and his wife were/are planning. Just thought running some ideas by a few here would help accelerate his intentions.........he and his wife are both academically trained, very successful engineer's, at a level only some of us would aspire to if we had the economic resources they have....that's all, plain and simple....!
As an example, at a little different level of aptitude........you, yourself, have had conversations, here at RTH, related to mechanical brake system's, which you are obviously well informed, that started to diminish to less than helpful or informative. Where you backed out of the conversation gently because you knew, from experience, there would be nothing gained or nothing lost by doing so.......on both ends.
I'm more than sure entropy may have felt the same........his tossing out another project, unrelated to the original subject, within the same thread, to drive more interest, may have been the bait that didn't get a bite here.......cut bait and walk away to fish another day.....maybe.
He may still drop by and show us his results........or he may have just taken another direction to achieve his goal.......who knows, I don't, but still interested in his process.
I'm not beating myself up one bit. I said what I said and will not retract anything said. I stand by every comment made, but do admit my "hitler specs" comment could have been a bit over the top, to some people.
To me it meant simply that he was shooting for perfection perhaps a bit too much.
I appreciate that you were able to see where I was coming from with the information I provided to the whole "brake issue". (I.E. difference of opinion on how a drum brake system actually works, VS how it theoretically works). Often theory is nice to have, but actual performance always wins.
I very much would like to see updates of his progress with his project with the tumbler, his Miata, etc etc. To me it's a large loss to not have him posting on here any longer. I however do not lose any sleep over it.

Parfive, I used to just let the slurry dry in 5 gal bucket outside about 3-5" deep, then tap it upside down on newspaper and throw in trash. Worked fine but sometimes the disk broke when I was carrying it. Now I pour slurry in some small cardboard boxes that I get Amazon orders or whatever in after tape sealing bottom cracks. Never pour more than 1/2" at a time. Now when they dry out I just throw whole box away. I'll go out in garage right now and take I pic for you. The cardboard sides wick out the moisture and dry it fast.

I have been told by several folks to let them know just before I move to a Smart Phone, they want to get their life in order as it's one of the seven signs!!!!

Wow, Knave, the cellphone photo upload worked! My menus were different from yours (I have a Motorola Android) but I found my way in there quickly. Just got back from 3 day rockhounding in NM.
That 2nd photo shows the misc. cardboard boxes into which I pour used slurry. Some of them are almost full and dried. When I top them off, and after dry, I just pick it up and throw the whole solid box/brick in the trash. I try to keep them such that the total weight is 20lb and under so don't break my trash can when banged around in the the trash truck. As the first photo shows, when I have reject rocks, I just put them in these boxes too and pour the slurry around them. I keep these boxes in a "rabbit hutch" liner plastic pan that I bought for very little at a farm and ranch supply, because leaks do occur and now and then. But no matter, just let it all dry and the box gets sealed by the dry slurry and I can continue. I probably am discarding about 20lb of dry slurry per week or so. Those 3 tall boxes are Costco granola boxes.
I have found duct tape works fine for sealing off the bottom box cracks. That first pour should be only maybe 1/8" to start the sealing. Then the next maybe 1/4" after first dry. This usually completes the seal by slurry. Then after that, no more than 1/2" or so at a time, otherwise the sides of the box will bow out and fail from the weight of the wet slurry. But after a good 1" or so of dry slurry, then pouring new over it dries super fast, because the dry underneath the wet just sucks out the water and it all dries quickly.
I've been using this method about 4 years now. You can see that one thin shoebox too. Just now realized something very important. I go around the top of each box with UPS type box tape which helps the shape and prevent blowouts in the top corners.

Conceptual question about grit being short-lived - Assume I put in a 50 pound sack of #16 grit black silicone carbide. By turning a large volume (of large rocks), the grit will consumed long before a week of tumbling is up. Would I simply add another bag in a few days? Does the pulverized grit need to be removed first? I'm assuming that my filler rock will also consume the grit. Are plastic filler beads ineffective for large-size tumblers? You would need to clean it out, because of the mud the rocks and worn grit would produce. If not cleaned out you would end up with an overflowing barrel of sludge. Cleanouts would be a b***h. That's why I don't own a Diamond Pacific 65T already
Thank you for reminding me about that. Similar reasoning. One day!

There's high confidence that one large rock rolling around a steel drum, cushioned by lots of smaller rocks & slurry will prevent bruising upon the large rock. Are we positive that several large rocks rolling around within a steel drum, cushioned by appreciable amounts of smaller rocks & slurry will NOT prevent bruising? If the answer is no, then the project is basically a no-go. Eric.D - please don't be intimidated by large parts. I've got a forklift, and a 16,000 pound gantry crane out in the shop. entropy - When can I come play? All the other kids have the best toys. Hmph.
