All of this is good info for me to chew on. I had no idea where to even start with thread sizes and pitch. I think i might buy some alumilite rods first before i rig up a whole casting system again. Eventually I will probably make my own, but for now 2 or 3 of the bought ones will be enough for me to look at for now. Classicnib.com has some longer rods that I think i will start with since you need more material length. I was either going to turn the nib piece as a seperate entity or make a seperate nib section and with a tenon and glue it into a predefined drilled hole on the body (no treads on this piece at all, in both scenarios) The treads would be on the body and on the cap only, and this way the only "non me-made" piece would be the ink refill. Would you guys do the same for the postable piece? Make the treads on top of the body a little smaller than the already threaded cap?
Also, Is there a place also where i can buy the die holder to fit into my drill chuck?
