CSUSA duo pen

[bdls]

Has anyone made these pens? My brother is a teacher and asked me to make him a dozen to give as gifts to some of his colleges at work for the holidays. Turning these kits wasn't much of an issue once I figured out how to turn a spacer for my barrel turner. The problem I am having is with the transmission/mechanism. I am not impressed with the action on any of them, they seem somewhat unsmooth or jerky. I have two or three that aren't working at all. Has anyone else had a problem with these? Any ideas as to what I can do to make the trans a little smoother? Thanks for the read and your helpful insight?

I find these to be very sensitive to barrel length, do not trim off any brass.

I've heard nothing but problems with them.

Who's the manufacturer?

I haven't tried the CSUSA Duo.. I tried the PSI 2-Way Tech.. same principle.. I got one good pen out of 5 kits.. also thought transmission was jerky.

Made 5 of each the duo and the p/p combo. Both are extremely length sensitive. The transmission doesn't inspire confidence...if they don't sell they will probably be holiday presents for the family.

I'm glad to hear others have problems with this pen... I thought maybe I just wasn't doing it right...

I made one of the CSUSA kits for my wife. The transmission works but it's "clunky" I probably won't make another.
