I started out just wanting to experiment with the M12 x .8 triple start tap and die I purchased in the recent group buy. I grabbed a couple short lengths of left over PR I had cast ....I chose it because I wasn't crazy about it, so no great loss if it got ruined. :biggrin:
Making the cap to lower barrel threads went easy so I decided to keep going.
I had picked up a rollerball nose cone that uses a M8.5 x 1 thread (since that was my second tap purchase). This one was a little difficult in that I had to run it back and forth a few times and then cut a little taper to get it to start. Looking at it I probably should have cut a little recess out to allow it to set in a bit more.
Checking my rollerball refill length I knew I had to add to the lower piece to gain the room for a spring, so I glued an extra piece of black onyx acrylic on the end. At this point I wished I had an appropriate size tap/die combination to make a removeable end cap. Maybe next time!:wink:
I then drilled out both barrels and proceeded to turn to shape.
I didn't really have a plan for the clip. I ended up using a Roadster clip and countersinking and notching it into the top. I then secured it with a finial cap I had knocked out of a Jr. Gent I. Not sure about this! I may do something different with it at some point.
I need to try and smooth up and break the edge on the bottom of the cap. Also I'm not happy with the rough look of the threads. I wanted to try to polish them but worried the polish would just stick in the threads and look worse.
Kind of like two lawyers at the bottom of the ocean! :biggrin:
Comments and constructive criticism appreciated!
Thanks for taking a look!
