great idea for brass trimming

I've been using Lee stuff to trimm my brass for awhile now. Its cheap and gets the job done, especially if chucked into an electric drill. But I never liked doing large jobs this way; for example, trimming 30-06 down to use as 7.7 Jap was always a pain. Often the cutter locks up and the base starts spinning in the lock arrangement. But I happened on a simple stroke of genius. As I was cussing the cutter, I happened to see a bottle of WD40 on the bench. I figured what the hell and sprayed it on the cutter. WHAT A DIFFERENCE! Now the brass trims effortlessly. Then back in the tumbler (after resizing) to remove any oil, and presto! Give it a try!

    Jonk: that's a no-no. WD 40 will enter the brass... go right thru it... and contaminate your powder and maybe your primer. WD 40 is great stuff, but must be kept away from your cartrigdes. Tumbling/washing will only get some of it off, not that part that enters into the brass matrix.

    Jonk -I'd never thought of using lubricants, but there are water soluble cooling / cutting lubricants readily available which should not present the problems described above. I know some of them have to be benign, because in one factory where I worked, we did some centerless grinding on metal OD seals that were incorporated into medical equipment & we had all kinds of FDA oversight on the manufacturing operations.

    Hey hey! I learned something here... so next I'll try Lee's case lube; it is meant to be put on cases and doesn't dry fast. Still, the idea of a lube has merit, even if it isn't WD. For that matter, a good gun oil should be ok, as proper oils don't mess up cartridges in the chamber...

    Try some mica dry lube on the inside of the case neck, thats usually where the binding occurs with the Lee trimmers.

    Try some kerosine. It's a good cutting lubricant.

    Try a mixture of about a third tube of Lee lube in 12oz.of rubbing alchol in a spray bottle.Will not harm powder or primers after it dries.

    I would try a couple drops of oil in a mayonaise jar lid. Just dip the case mouths into it. That should be more than enough to lubricate the cutter, but not alot to contaminate your media too quickly. I would use something liquid not greasy. My theory is the liquid would clean off the cases faster.
