When I have thought about the process of threading the parts, my concern has been threading the outside of the nib section that screws into the pen barrel, and the inside thread for the nib housing. What worries me is the potential for cracking the nib section during threading. Having not actually tried this yet I would think that having the maximum amount of thickness of material as practically possible would be a good thing? Am I over this thinking the process? I refer to using acrylics, metals I can appreciate.
Looking forward to seeing the outcome of your endeavours with this Phil, and I salute you for taking a lead with this. The cost of the taps and dies from that US supplier for triple starts is rather prohibitive for me and I was going to be happy with standard one starters.
