Sedona Thread Sizes?

[Tangoman]

G'day Folks,

I've been messing about in the garage trying to do things above my skill level !!

I've managed to make a couple of closed end pens using the brass tubes and now want to try making them without the tubes BUT I can't figure out the thread size and pitch to be able to connect the kit section to the body.

Does anybody know what the thread is ? I want to use the bits from kits I have at present. They are a Sedona and some Tycoons, I suspect they might be imperial thread sizes, which is a bugga cos I only have metric !

Thanks in advance,
Cam

The Berea Baron/Sedona section to body thread size is 8.4x1, also used on the Sierra transmission, available here

silverpenparts.com - TOOLS - Taps and dies

Not sure what the Timberbits Baron/Sedona uses.

GPW Baron/Sedona components differ in outer dia to Timberbits from memory so thread may also.

Something is different anyway - pretty sure it outer dia.

Thanks for the help fella's, much appreciated !
i'll take them into work and see if anybody from the engineering team can identify them or teach me to use a thread gauge properly !!!

I'm looking very closely at a baron from Timberbits, it has three parrallel threads - three thread starts. So the actual pitch is three times the measured pitch.

I don't know if I have explained this well - maybe someone with a bit more engineering knowledge can help.

Yes, commonly known as triple start threads. But this is on the cap to barrel thread, the OP was asking about the section to barrel thread, which is a single start thread, M8.4x1.

I have looked at my records for the various pen kit dimensions and the Timberbits Baron/Sedona and the Berea (from which it was copied) are the same.

The Dayacom (the one GPW sells) is different and larger as previously pointed out.

I'll have a look what the triple start thread is on the Berea/Timberbits version.

Thanks for the clarification BigShed.
