I am planning to make my pens as possible as custom made, so I need special metrics for threading.
There are many threading solutions, I know Tapping is one of them The matter is the taps and dies with triple/quatro leads are so expensive. They are made of (oftenly) HSS, that is why lifespans are not so long.
My commissioners are asking for usually 12mm, 13mm, 13.5mm, 14mm, 14,5mm and 15mm multistart barrel threads. The total price for a whole set is not so affordable recently.. That is why I decided to make them manually, I have some solutions to make it easy There are couple of videos and essays I ve found on web, they are all about metal threading. The materials we are using are not that much strong, mostly thel are brittle..
As I succeed to make a proper one, I am going to share all stages here. I am just curious if anybody made anything about this problem? Is there anything to be aware of before starting
