I was putting a Perfect Fit pencil together and thought, I wonder? It was one of those "can I do it?" moments.
It's a Schmidt pencil mechanism installed in a Delrin nib assembly that screws into a 25.06 casing.
I enlarged the case mouth so the bullet slides freely and allows you to "click" it with your thumb.
The Delrin is one piece and is threaded on the inside for the pencil mechanism to screw in to. The bullet is drilled about half way with a #34 bit and the little cap piece is a tight pressure fit.
The casing is threaded with a 5/16"-24tpi tap to accept the nib assembly. The inside of the nib assembly is threaded with an M6X0.75 tap to accept the threads on the pencil mechanism. It's an oddball tap so keep that in mind if you want to make one. MSC has them for about $6.
This last photo is the drawing I made. I always make little drawings when I build things, it helps to keep my mind straight!:wink:
