Heads Up for L.E. Wilson case trimmer users

[burneyr]

I had to get some items from Pacific Tool & Gauge today and checked out their specials page.

Lo and behold Dave is offering carbide trimmer cutters for $10 that are made for the L.E. Wilson case trimmers.

Always wanted one, but the $70 cutter Sinclair sells is pretty nuts. Granted, theirs does come with a $15 handle.

Anyway, thought I'd mention it to everyone if you need a new cutter, or would like the benefits of carbide. Ought to be the last one you would ever need to buy.

Thanks for the heads up. That is a great deal.

I want to throw in that the case holders from Wilson... or actually the Wilson imposters from Sinclairs, are NOT always true. When you check them put a case in the holder and roll it on a table top. I put mine in a lathe and place an indicator in the opening that has been cut like the chamber. A couple have really been bad. Neighborhood of .015" to .020" On match brass that's too much.

Not meaning to put Wilson or Sinclair's down. Just check your equipment.

When it comes to trimming the brass true, whether the opening in the holder has zero runout has no contribution, as long as the bore is parallel to the outside. Making a single measurement on one end won't tell you that. If you can chuck it between bullnose centers, and turn it by hand noting the position of max runout, then if the max at both ends does not occur in the same spot on the rotation, then you have a problem.

Having the bore true to the OD was my whole point.

Re: Heads Up for L.E. Wilson case trimmer users

My point is that the way the wilson trimmer works, as long as the centerline of the bore is parallel to the centerline of the OD, the trimmer will cut the case mouth perfectly square. It is entirely possible to have the bore not centered in the OD, but still parallel to it. Measuring runout at only one end of the holder will not tell you whether it is parallel or not, even if it has zero runout there.

I agree. But the odds of that are very slim. If you put a case in the holder and roll it on a table top and it looks like a dog with a broken leg... your case mouths will be out of square.

Re: Heads Up for L.E. Wilson case trimmer users

I'm not sure about the relative odds. It is relatively easy to get parallel with good jigs in an efficient production setup that is even immune to dimensional errors in the stock OD, as long as it is cylindrical. It is a lot harder to get perfectly centered unless the final step is to turn the OD while the holder is held between bullnose centers in the ends of the reamed bore. That's awfully expensive for production. I'm betting they use ground round stock, cut it to length, bore it and ream it.

I know of at least a couple of users that have found them off center, but still reliably cut the mouths square. Using the holder in a cartridge TIR measurement was impossible.

Victor, I understand what you and BigJake are both saying, and all I can tell you is using a dillon chamber type case gauge, the mouths after trimming are perfectly square to the gauge or so close as to not have a visible discrepency.

burneyr, thanks for the heads up buddy

Just emailed them so hopefully I can order one before they run out.

I use Dillon's chamber guages as well.
