The sole purpose of a rifle is to please its owner

There is at least one simple way to do this... maybe some of the other guys can come up with something better for you. My solution was to spend about $15 to get the Lee trimming equipment that is already designed to mount on a drill. Works great!

I put my forester into my drill press works like a charm..

I should add I have it mounted on a priece of 2x4 and then mount that into the drill press vise.

I use an electric drill all the time with the Lee case trimmer. The idea here is that Lee makes a lock stud that the shell holder screws onto and then the base of the case fits into this lock stud-shell holder assembly. The lock stud has a protrusion that fits into the electric drill. This assembly then spins the case.

The cutter is threaded onto a case length gauge that you insert through the mouth of the case and that goes out the flash hole and meets the lock stud. Holding this assembly (cutter threaded onto case length gauge) still in the mouth of the case while the case is spinning allows the cutter to trim the case until the length gauge meets the lock stud, at which time the cutting ceases.

You need only one lock stud and cutter because these are the same for every case. You do need to buy a different case length gauge for each caliber, and the case length gauge is supplied with a shell holder also.

I think this is the fastest case trimming system in existence. I always use it to trim all my cases each time I load them. The only disadvantage is that this trimmer is not adjustable, because the case length gauge is a non-adjustable unit. But who cares? All the cases are trimmed to the same length, meaning that you achieve complete uniformity. And isn't that the goal, after all?

While I have the case in the assembly mounted in the electric drill, I also use a case chamfer tool (RCBS from Wilson) to chamfer the inside and outside of the case mouth. I also can use this to clean the cases by spinning them in a cloth soaked with Remington Brite Bore cleaner, or, for more vigorous cleaning, a lump of steel wool.

I use the Lee trim equipment. The cutter and two chamfer tools are mounted in a homemade block that has three holes drilled through. Each of these holes has a 90 degree hole drilled and tapped for a locking bolt. the tools are set in and locked with the bolt and the whole assembly is screwed to the bench. this leaves my hands free to mount and dismount cases in the drill. If I could figure out how to post a picture,I could show you what it looks like.

Mike....Sinclair makes a handy little holder that clamps onto your bench that will hold an electric screwdriver that is just about perfect for trimming cases (and neck turning and a variety of other things) that frees up your hands...they also sell a variety handy litle tools to do things like trimming. I think their web-site is www.sinclairs.com bu
if that isn't it you can go to www.benchrest.com and look on the list on the left under components or tools etc. You really should have their catalog...you won't believe the things you just asolutely need to have.

Mike, I turned a shaft in my lathe to fit a 1/4 inch 7.9 volt cordless drill. the ID is drilled and taped for my forster trimmer. Next thing I will try is to rig up a foot control switch like sawing machine so i don't have to use the trigger.

Go to lyman products, you can get the whole kit that is set up for your drill. chamfer, debur, case neck cleaner, reamer, and cleaner for primer also. The whole kit costs 29.95. Luck hotdog

Dillon's Rapid Trim 1200B Case Trimmer.
Expensive, dies are sold separately, need dies for every caliber. It is fast and with the vacuum attachment is is very clean.
Is it worth it? You decide. I think so.

I use my Lee gear with a drill chuck, but the other way round - with the cutter & case length gauge mounted in the drill which itself is clamped into the bench vice. I set the drill on slow speed and only do this when I've got lots of thicker cases needing trimming. For the odd .22/250, I'll still do it using Swedish steam.

Have three forster trimmers set for different jobs,Trimming and outside neck turning. Forster sells a adapter for a drill, I use a 18 volt cordless with a 1/4" nut driver which fits the adapter. With the outside neck turner I make one very small cut and check the runout, if it is still out with the second one I make a second cut. If you only make one cut to the final size you can have problems with the brass on your collet pilot getting hot and doing damage to the inside of the neck of you case. On my benchrest rifle the cases are .0086 thick on the neck because of the tight chamber. Good Luck

Mount the Forster on a piece of wood and "C" clamp it to the top of my reloading bench, all three are in a row. Forster makes quality products and to get started check places like E-Bay and Gunbroker for used ones. Good Luck
