anybody have an idea where I can find this? Neco has it cheapest at $15 plus shipping, I am looking to spend less if possible.

clover only has it by the pound....

thanks

I have some used 600 grit I'll sell you...

I don't know where you're at but check companies like Graingers. Any industrial supply shop should have lapping compounds.

Isn’t JB somewhere in that grit range?

It does cost about $3 bucks a jar though, is that too expensive?

good one malm!!!

JB is made from garnet, which is softer than barrel steel, which won't serve my purposes. I checked. good idea, though.

Go to www.cheapshitRus.com they have mislabeled stuff and have some 1200 that is actually 400 grit but the label says 1200. Probably real cheap. Won't work well but you will like the price.

Don't know what you are lapping but i have read somewhere that garnet doesn't embed in metals like other compounds. It might be what you really need.
Why 1200 grit?

I think Crest toothpaste is about 1200 grit ain’t it?

In short, the answer is no, no one knows where you can get lapping compound for cheaper than it costs to make.

$15 and shipping (us mail) should be under 20 bucks...

how much lower, perdactly, do you want to go?

About 3 years ago there was a fellow in AK that sold some 600 and 1200 grit powders on one of the gun boards. I think it was about $8 ro $12 for two vials of each. Mixed with Norton Oil, it works great and lasts a long time.
Now that I know that it is really valuable I'm putting it in the safe and restricting it's use to really important projects.
Diamond is available from many different sources and is not really that expensive for what you get and for what it does. And available down to single digit micron level. Color coded for i.d.

Nobody could ever replace you

I am fire-lapping a mosin-nagant barrel that shoots very well for the first 10 shots then opens up. it is not barrel heating, as I let it cool, and I have not taken the action from the stock, so I think it's a clean barrel/dirty barrel thing.

as the rifle is a mosin nagant, I do not have much in it.

I picked up a Midway lapping kit for about $15.00, but the finest grit is 600. I saw NECO has 1200 grit and that seems like a great idea, but NECO's 1200-grit will be $20 or so delivered, a substantial portion of the cost of the rifle.

I see that my frugality offends people like chic for some reason, but I find it difficult to spend much on an inexpensive rifle. so I am looking for 1200 grit that will polish steel, but am reluctant to spend $20 on it.

I was hoping to get out for $10 or less.

I sold auto parts for many years and sold much lapping compound for far less than $20 per pot, even accounting for inflation.

that experirnce, coupled with my low inital costs in acquiring the rifle, militate against spending much on the 1200-grit coumpund.

of course, if I ever decide to restock my mosin with walnut grown from the finest root stock used to make furniture for French Royalty, fertilized with ortolans, blessed each year by the Pope, watered with the dewey peepee from virgins raised in a convent secluded in the swiss alps, which walnuts were used to make cookies for starving orphans, well then I will no doubt seek the services of chic so he will have something useful to contribute to my life.

until then, I will unabashedly seek the cheap way out, and rightfully so.

thanks!

There you go. If you really want to save money, use the 600 grit, recover the bullets and use them again.

I would imagine South Texas dirt would be very close to 1200 grit.........I would consider selling it for 15 dollars per pound plus shipping .........well it hasnt rained in 8 months.

If you're trying to smooth out the bore of a Mosin, buy a case of ammo, a one piece cleaning rod and jag, and a case of patches and start blasting away. If you put 400-500 rounds through it and clean the bore thoroughly every 5 rounds, I doubt seriously that you'll ever get the bore any smoother than that. And you do not have to buy any of that expensive lapping compound to do it!

delloro,

1200 is about 3 micron size, did you want silicon carbide or aluminum oxide. I sell a lot of abrasive in the course of a year but all in large quantities. Send me a PM and I can see if I have a little sample of 3 micron around somewhere I can send you.

You know, if you go to a wood finishing company you might be able to sneak around back and do some “dumpster-diving†and scrounge a used piece of 1200 grit sand paper and then scrape some grit off the corners where is hadn’t been used! Of course, that raises the question about where are you gonna get some cheap razor blades to do the scraping with?????

Trust me when I say 600 grit is all you're gonna need. Any finer than that and you wasting your time and money. Especially on a milsurp.

If you want som effect on fouling you should go for some grit 220, because its capability to remove toolmarks, and create som degre of microrifeling, reducing the bulletjackets tendency to stick in the barrel

Not that I would ever use this in my rifle bore (I wouldn't), BUT...

As you sold auto parts/grits for years, have you considered looking up what size of grit(s) various paint polishing (rubbing) compounds are? Or maybe you could use Flitz, basically a silver polish, like the British target shooters have done for about 30 years.....


(N.B.: I have used Flitz in my various NRA (DCRA too) match & Palma rifles. It cleaned their bores very nicely and did not harm them...at least not to the point it showed in the scores they were capable of...)

I don't have any idea where to acquire 1200 grit lapping compound but this thread has damn sure been entertaining!

I agree with Rusty in that 600 will be as fine as you need.

Gringo, Are you sure about that South Texas dirt bein that fine? I was thinkin it would be just a might courser than that. 1200 is finer than fly poop! Jim

Nothing is fine about fly poop! With a dairy startup operation for a neighbor, I have become quite familiar with fp and it covers everything in about a #9 shot size splat Maybe some of those costal mosquitoes could produce poop of the appropriate size.

BigB, that is very generous of you, but I think I will just go ahead and get the Neco stuff as there does not seem to be much of an alternative.
