PSI fiber tip / fountain pen cartridge
Blank is from PSI $1/blank grab bag used for prototyping
Capped: Overall length 5.25", 135mm
Cap length: 54.1mm
Cap OD: 13.50mm
Cap thread: M12 x 0.75
Cap stepped from threads to 7/16" to "M"
Cap turns 3.5
Body length: 85mm
Body OD: 12.0mm
Section threads: m9.5 x 0.8 ( actually 3/8" x 32tpi but it's easier for me to deal with metric units)
Section 19mm + threads
Section internal threads m7x.75 (SKM-88 clicker threads)
Section OD max: 11mm
Section OD waist 10mm
Q,C & C appreciated
Suggestions for improvement or streamlining the process welcomed
Toolmarks still present
Got a bit overzealous with the thread lengths
Threads need a good polish
