Could someone (or more than one) verify my measured thread sizes for the El Grande rollerball/fountain pen kit, please:
Metric threads
Finial end: 10 x .75 single thread
Feed: 10 x 1 single thread
Cap/Body: 12 x 0.8 triple start thread
Cap/Cap: 8 x 0.8 single thread (this is the black cap on the closed end of cap)
I am pretty sure of the thread pitch, but not so sure of the diameter.
I am getting set up to do kitless and thought I would start by copying the El Grande.
The reasons I made this choice are: I already have the Cap/Body tap&die (albeit, in double start thread); the Feed tap&die is readily available at HF and Princess Auto; if I start with a closed-end design that's all I need for starters.
Also, what size holes do I drill, and what size tenons do I cut, please, for the various tap&die requirements ?
Thanks !
