Question on Modified Wilson Seating Die by Erik Cortina

[K9TXS]

The video below shows a modified Wilson seating die by Erik Cortina. He simplifies the adjustment by not having to use the allen screw, but doesn't say what he did to it. He says that he will make a video showing what he did, but he never made the video. I've reached out to him on three different platforms but have never received a reply.

The only modification I can think of would be add a groove around the upper portion of the die, under the micrometer adjustment and then add an O-ring. This would allow some tension when adjusting the micrometer.

Any ideas?

The video starts around 32 where he describes the die.

Much simpler just to get a set of Skip Otto's dies shims from Brownell's!

Or you can get a Micrometer top from Sinclair/Brownell's. If you want to make it adjustable with friction only, you can probably put a short piece of Weed Whacker nylon line between the set screw and the die threads and adjust for desired tension.

I think the Wilson's come with a fiber pad on the end of the setscrew. Mine did, anyway. I will say the tension adjustment is pretty abrupt (nothing to locked in a small fraction of a turn), but I don't have any problem with it drifting in any case.

There are polymer tipped set screws and spring loaded plunger tipped set screws. Check them out at McMaster Carr.

Cutting an o-ring groove the the main body unnder the micrometer head and installing an o-ring would be my choice.

You can also put a small piece of string trimmer line if you want to make your own polymer tipped screw. Works great and I've done it on a number of things.

I have used a thumb screw with a winged head from the hardware store in lieu of the allen head screw.

a light tension with the allan wrench and its still turn but not free spinning. I just went out and took 3 of them I use apart and they have something in there the screw pushes on, and lookong from the inside whatever it is has threads from the case holder part that look just as shiny as the micrometer top threads. Looks like it could be a lead ball. They wouldn't fall out so I didn't pop em out. I've never had a problem with any of mine moving without me intetionally moving it, and I use them alot. Because every 100 firings I strip the bolt down and check the bullet to land touch and adjust bto appropriatly, if nessesary.

I manufacture hydraulic cylinders and the gland rings I make I install the above nylon balls under all my 10-24 tapped holes to prevent any thread damage and for easy of disassemble down the road. In your case you would just put slight tension on the set screw to create drag.
