Wow.....that in itself is a piece of art. Very nice.

Man, I was not expecting to see any this nicely done. Very neat. Thanks.

That would sure be an interesting way to do it. Prob. not cost effective though in most cases.

I cannot imagine anything that works any quicker, easier, or is any less trouble to make than one of these. This is one of my case trimmers.



With it I can trim a case in about five seconds. Blade is replaceable if it ever gets dull. Blade is not at 90 degrees to the axis of the dowel, but is very slightly downward angled in order to give it a quick "bite" into the full length hull. A thumbtack in the end of the dowel, even with paper shims under it, can vary the length of the cut hull to suit.

Maybe this is a weird question but how do you get the blade into the dowel?

[Stan Hillis]

Not weird at all, Joe. It took me awhile to figure a way myself on the first one I made. What I do is make a pencil mark on the dowel indicating where the blade needs to be. Then I drill, with the tiniest drill bit I have, a series of holes as nearly connecting on the line as I can. Then, I put the new blade in a vise, with the jaws clamping the sharp end tightly, and the square base of the blade pointing upwards. I align the holes I drilled in the dowel with the base of the blade, and tap on the other side of the dowel with a hammer. Doing so seats the blade in the dowel firmly. Never had one come out yet. But, the blade could be clamped in the vise again, and removed, by prying upward between the dowel and the top of the vise jaws.

Doesn't take much longer to do it than it does to type it all out.

That nondescript 10 gauge barrel cost me 10 bucks at a gun show.

I did try a dowel cutter but because of variation in the depth of the base wads the cut shells had a +/- tolerance on length. Not that it mattered all that much when crimping but I wanted hull uniformity by use of a cutter that indexed from the shell rim not the base wad.

I put a adjustment screw at the bottom of dowel ,screw in to shortn hull back screw out to cut hull longer, works great for different brands of hulls. Been cutting 10 ga hull with that type trimmer sense 2009 with no changes, it works.

Thanks for all the replies yall. I'll be trying to make myself one here soon.

Joe, I bought a "spin-n-trim" from BP and made mandrels for 20, 16, and 10 with adjustment screws like the original. About 2 seconds per hull, less than 2 minutes to change gauge. If you use different brands of hulls it's very simple and quick to adjust length.
