I had ordered 5lbs of this pre-polish last week and received 5lbs of 60/90 grit yesterday. Close, but...
The correct stuff is supposedly on the way now.

Dang it man, I told you about the 5000 captbob. Wait a day or two before you use it. I just put this load to tumbling in 5000 this morning. I will know soon like tomorrow if it is in fact 5000. If it is not it will have removed the so so 1000 polish in short order.

I don't get it. ? You told me you found it at Lortone and therefore I ordered some last week? Was I not supposed to order it for some reason? They just sent me the wrong stuff on the first try.
I don't need to use it anytime soon, just getting it to have on hand.
IF it's only 1000 and not 5000, I wonder if you would even know. If it doesn't degrade the 1000 "polish", it may simply add to it as though you ran a second round of 1000.

But i could be mistaken. I really can not say for sure w/out a microscope. Just going by looks and feel. If it removes the mild polish on my tumbles then I will know that it is not 5000. I washed the 1000 off this morning. They were done w/the 1000. Now the rocks are running in Lortone's 5000. Yes, I will know. The rocks should get a higher polish if it is 5000.

For it to remove the polish from the 1000, wouldn't it need to be coarser than 1000?
Wouldn't the "polish" also improve by running 1000 a second time or for longer?
I'm thinking it's gonna be tough to tell, but I hope there is a noticeable improvement!

Running in 1000 again should help the polish. I will know tomorrow when I pull some samples and will let you know if the 5000 is 5000 like Lortone says it is.

I'm thinking it's gonna be tough to tell, but I hope there is a noticeable improvement! I say this is 35 micron(500 grit). Not 5 micron as Lortone says. 5 micron is 4500 grit. this shit feels like 500 grit. 1000 feels like talcum powder. 4500 should feel like talcum powder. I could be wrong, but my mediocre 1000 grit(18 micron) polish is gone in 8 hours. The lady at Lortone told me twice it is 5 micron. Grit - Micron Conversion American Standard (Grit) Micron 100,000 1/4 60,000 1/2 14,000 1 13,000 1.5 9,000 2.5 8,000 3 5,000 4 4,500 5 2,800 7 1,800 9 1,400 14 1,200 15 1,050 18 800 25 600 30 500 35 325 45 285 55 240 70 225 90 160 110 100 150

I had a hard time finding 5000/4000/4500(i.e. ~5 micron). It is typically a lab product and very expensive.

The Rock Shed sells a 500 Aluminum Oxide.
Says: This is 500 Aluminum Oxide grit. This grit works great for the fine grind (pre polish) in a rotary or vibrating tumblers.
yup... I'm thinkin' we have nice expensive batches of 500 AO. I don't even use this 500 AO, at 500 I use Silicon Carbide.
c'est la vie

I don't even use this 500 AO, at 500 I use Silicon Carbide. c'est la vie When Lortone called it pre-polish I figured it must be 500 AO, maybe 1000 AO. That's why I called them to reverify. 5 micron/4500 grit is not a pre-polish, it is polish. I do use Rock Shed 500 AO, it is way cheaper. So yes, looks like we are proud owners of Lortone 500 AO. so now I have to rerun the 500 till it breaks down and rerun the 1000 till it breaks down before moving to 14,000 AO. Add 12 days to the tumble,ha. I have both AO and SiC 220 and 500. They seem to do the same job on agates. But for obsidian I would use your new AO 500.

Maybe you can rub some of the 1000 AO on a piece of window glass and then rub some of the 5 micron from Lortone over the same spot to see if there's a 'grit" difference? connrock

Wished I had thought to do that. What was I thinking, it is already in the tumbler conrock. feeble mind.... I just knew that was not 5 micron. Next time there is a question it WILL get the glass test comparison.

So that is 10-12 days to run those grits AGAIN. Your suggestion even frustrated me more because of my own stupidity. LOL. Funny how tunnel vision sets in. Funny how unexpected change of plan reduces IQ or common sense. I do appreciate you pointing out the error. Much prefer someone pointing out stupidity. Love working w/skilled folks. The theory they taught me in school was always a source of their ridicule. ha i always found that to be the funnest part of the job. Every once in a while I surprised them, they always amazed me. and I let them know. Those guys taught me to weld and I ended up being a cracker jack welder, often having to do some of the welds that they were concerned about. Even the union let me do the hands on. It was a big deal for me.

James,,, We ALL have tunnel vision at times! You're "doing it" and all I'm doing is "reading it" here so it's easy for me to think outside the box cuz I'm not all wrapped up in the actual "doing it" thing! It's easy to "correct papers",,,,especially on experiments!
Welding: I never had any formal welding training but learned how to stick 2 pieces of metal together on my own. My son never had much interest in my welding during his teens,,,tried it a few times and that was that. When he was about 19 years old he became a sheet metalman apprentice and about 2 years into it he told me he was taking a welding test that night.I had never seen anything he welded and when he came home that night he was all excited about 2 sets of 3/8",,,6"x6" plates he had welded in the welding test.I was impressed but not overly impressed cuz it was just a couple SS plates welded together.I looked at him and said,,,Oh,,,that's pretty good,,,,,,,nice welds.He looked at me with a sheepish grin on his face and said,,,,Dad,,,,that's overhead!!! The would-be teacher (me) just became the student! LOL

Hahaha, I would not have thought of the glass trick either. Doesn't make you stupid like conrock said. Much easier to see from the outside.
When I was pipe fitting steam instruments and stainless tubing my boss would walk up and point out any errors. After a couple of times I (duh) figured out that if I would walk away and look at it I would see them and make adjustments before he showed up. No problems after that. Sometime you just have to walk away and look at the whole picture.
Connrock I loved welding and it was a sad day when I had to quit because of my back. To me it is another art form and I know a lot of people that can talk the talk but not walk the walk. If your son passed the overhead he is doing pretty good. The toughest test for me was overhead tipped up 45 degrees and turned 45 degrees. Pretty easy with stick but with the wire feed turned way up for structural steel specs it is a bitch. Jim

Jim The pipe fitter guys are some real welders. The common welding test is to butt weld two horizontal pipes together. Welder forced to weld in every position of 360 degrees. presto, instant test. If he can lay a nice bead 360 then he is probably pretty darn good. Pipe fitters get that test about every other weld. Leads to psychosis (Jim).

I am thinking that the Lortone polish is probably 4500/5 micron, not the pre-polish. Then they have a super polish which is probably 1 micron. Will call Lortone back and question. Not give up.

It is pretty obvious you do not give up easy. Well, except where the wife is concerned and that is true for most of us men. I call it compromise but it has a lot of other names. Jim

Jim All that hard work we do is easy compared to the other subject. Seems like the biggest baddest dudes I know get reduced to putty by the ladies. I found the 70/30 works, me 30 and her 70. About as close to compromise as it gets if lucky. Lest you have a better way
