              Thought I'd play around with crimping 12g shells in a vintage crimper that I have.

Without buying a trimmer what's the best homemade device you've come up with ?

I've tried a few different ways but want something that will give me more reliable length &  evenness.

Thanks.......

I've modified a few steps but essentially come out the same.

 

I trim the hulls with the same dowel and knife method but recently bought a pair of $1.88 "gripper" gloves that reallly make turning the hulls much easier.

Good Morning Painted Mohawk:
There is excellent information and a great tip for trimming your shells in Tom Bullock's helpful page.

Find a piece of PVC pipe that the shell will slip into. Cut it to your desired length. Insert shell and cut with sharp blade to length.

I've made black powder blanks and trim them using a dremel cut tool mounted in my drill press, just set the table height for your desired height and it's quick and consistent..

I built a little sled for my bandsaw that does an excellent job of trimming the hulls. I trim 400-500 every now and then and it takes an hour or so. I then use a homemade skiving tool in the drill press to thin the end of the hulls that I’ve trimmed.

Are you successful with roll crimping plastic hulls with an antique roll crimper?  I use a BPI tool in drill press.

No comments on trimming or crimping, just glad to see you on the Wire after last night’s storms.  Back to the topic...

Jefferson City is about 25 miles south of us.  Waiting for reports to come in.  Probably lots of other damage in path.

I was given a trimmer similar to the one in this video & it works like a champ.  The one I have uses an Xacto knife blade instead of the trimmer blade screwed to the dowel.  Looking for a picture of it now.

 

 

The blade in my trimmer works like the one in this video, you mark the length you want, then stick the Xacto blade in the dowel at that point.  Angling it about 30 degrees works best.

This is the next reloading skill on my list, Hollifer.  I'll talk with you about it this weekend.

I duck taped a paint stir stick on the right side of the blade on my band saw.  This is almost the right height for the rim.  Then I just trim off where the fold starts and call it good.   I have an old crimp roller but the one from BPI works much better especially if you add a little bit of wax or lube to every 5 shell.  Need to get it hot and do all your shells in one batch.

This looks to be almost as much FUN as annealing a batch of 45 Colt rifle cases  :wacko:

I used the same method as Hollifer and it worked really well.  One change I made is I epoxied a broken 1/4 drive drill bit to the  dowel and use my power screw driver to spin it.  The screw driver is a cheap B&D and turns pretty slow. Use a grip enhancing glove and be careful. That sharp blade will easily trim a finger.

 

I have an old antique roll crimper and it works really well. Secret is to make sure it is securely mounted so that it cannot move.

Ah yes ... But ... iffy you loads All Brass 12Ga hulls ... case trimming, resizing and CRIMPING is of no importance.  Unless of course some Ham Hock steps on one.

I was able to get a couple of pictures of my trimmer, along with a short video of it in use.  Like Dave said above, my trimmer has a rod inserted so you can run it in a power drill.  I used it to trim 200 new hulls for the ammo we will use at EoT, it took about 20 minutes.  If you are only doing a few, holding it by hand works fine, but for volume work, you can't beat the power option.

Not sure of the age of the crimper, got it for $50.

I used  a piece of  poly water pipe for trimming but not real happy with that, going to a gun show & swap meet this w'end & will look for a vintage cutter,still using a plastic wad ...I found that by running the finished shell thru the final crimp stage on the Mec Jnr  they  are even better.012.thumb.JPG.c15b2d48c4f54fea3521eda80370fdae.JPG

3/4" pipe, an end cap, and a sharp knife. I glued a short piece of dowel in the cap so it screws onto the pipe tight and the shell isn't loose. The shorty is for 1 3/4"ers. These were old, used pipe nipples, hence the pipe wrench marks - I don't use a pipe wrench to tighten 'em in the cap. :lol:

Tough to get enough friction/heat with a vintage hand-cranked roll crimper to get a nice roll - buy one you can chuck in a drill, as suggested above.
