Hull Cut Off jig

[William Davis]

Tried them all none suited me, then used the sliding table on my table saw. Liked it but wanted something dedicated to hulls and not tie up my sliding table. Came up with this rig

It's half of a sliding table. Indexes underneath in the saws miter gauge slot. 4 holes, two will do 10 & 12 other two 20 & 16. You could run one (or two) gauges or perhaps get more than 4 holes. Top is spring loaded back off on the wing nuts it lifts off the shells. In practice get it set all you have do do is take a half turn off the rear wing nut !!! when the blade stops turning!!! and slide out the trimmed hull. I was indexing from the front of the hull with a stop using my regular full sliding table, but got inconsistent lengths off the hull mouth. Rear just use a pencil line scribed to set length.

Fast and precise, smooth cuts.

Great idea!!! What hulls work the best for re-crimping and do they need to be skived also?

[William Davis]

They need to be skived, not much burr but enough it would hamper wad seating.

New 3 1/2 10 G down to 2 7/8 crimp fine. Getting ready to run another 100 Federal 10s. I would assume any gauge new un crimped hull would do as well.

Most cutting has been the entire fold off fired 2 7/8 inch 12 16 & 20 to make short hulls for roll crimping, I don't known well a fired 2 7/8 would do cut back to 2 1/2 then fold crimped. Cut would fall mid way old crimp. Would it crimp again possibly, indexed on the hulls rim length would be right.

William, I trim mine with a pice of dowel with a #11 exacto blade driven in at the right length, one turn and it trims perfectly with a nice clean cut. Crimps fine with no skiving. I have tried Remington, Federal and Chedite hulls and all seem about the same. You need to make one for each brand of hull since the base wads may not be the same.

I made a simple jig with a lever that has a razor blade clamped to it. A dowel, turned to 12ga on one end, and 16 on the other (the only two gauges I trim to load 2 1/2") is adjusted so cut the correct length, as the shell bottoms out on the end of the dowel. I trim leftover 2 3/4" RST hulls and new paper hulls. Each hull requires about 5 seconds to trim to length. Cut is as clean as the uncut hulls from BPI.
With the leftover little rings you can make nice mobiles to stare at during dinner.

You make me laugh Edgar.
That's a great little setup for trimming hulls!

That coffee grinder up above the cabinets... Is it a Parker? If so, what model is it?

[edgarspencer]

I have to edit my pictures more carefully. I forgot how you scrutinize them.

No, That grinder is an Enterprise. My Parker is too heavy to put up there.

At the risk of being flogged, I think Parker stole their design from Enterprise, and not, as some think, the other way 'round.

[Dean Romig]

Consider yourself handily flogged :nono:

As I have been accused of - you have toooo much time on your hands.

I have the same but with a round head wood screw in the end so can adjusted for any hull.

Edgar, I had a nice Enterprise grinder and coveted a monster Parker 900 in an Eastern Shore antique shop. The 900 had little original finish and the dealer traded me even for the Enterprise. The 900 is the only one I have seen for sale.

[edgarspencer]

Bill, I went to an auction last night, on the spur of the moment, based on a phone call 30 minutes before the auction started. They had a nice nice original No.200, and while that's a fairly common model, in this condition, not so common.
I made a quick call to my 'expert', Mr. Romig, and on his guidance, dropped out in the low sixes. What killed me about leaving it, in the drawer, was the original Parker open end wrench, which I have NEVER seen before.
I took the money I saved, by not buying it, went over to Dover Furnace, and had Ralph "Lefty" Fabricius measure me up fora pair of triple vamp Russel Bird hunting boots. I asked him how long he had been with Russell, to which he replied "I married the owner's daughter in 1953."
Interesting sidebar, he said his uncle was Charlie Larsen, who won the GRand American, in 1919.

I like that story a lot, but I am a bit stressed in my schedule for investigating ATA trapshooters. Give me a day or two. Oh heck, I looked it up and Charles won the Grand American in 1917, not 1919. Congratulations, Charles.

[Patrick Barrett]

Amazing. I wish I could do that. I am all thumbs.

i also copied a hull trimmer of someones here...it has dowel with exacto blade a screw to ajust hull lemgth..i do 8 ga and 10 ga mostly on it...it will do 12 ga easy enough but have never tried 16 or 20 s on it....just got to be careful and not cut your self...charlie

I like that style best, too. Quick, clean, easy to make up for different gauges and lengths.

Since everything I shorten ends up being roll crimped I don't have to be concerned with skiving.

Edger, had a buddy who has a wood working shop and loves to make things like yours make me one. It's a little bigger. Man does it work great. Thanks for the idea.

I use a trim doctor, available online from balistic products. It is good for whatever gauge you desire. Just buy the dies kit for the gauge you want
