Stock cap but a few changes on the barrel.

Threads on the end for the final to remove to use the converter and threads for the section.

Not sure where the pics went so I will try again

Is the converter mounted permanently?

Yes it is as I wanted one that would not leak or fall out on me.

Interesting approach, Chris. Did you make the green piston end for the converter?

I wish but no I found it in my parts box and thought the green matched perfect. I used the new tap m10 .75 for the blind cap and it all worked out real good.

What are multi start taps? Where did you find them?

Thanks

The multi-start taps were sourced from E-taps in Florida. The IAP guys did a group buy, as they are special order and buying them as one-offs is outrageously expensive. They are 3 start threads, 12 mm, and allow you to get rid of the insert in the cap and the corresponding male threaded piece on the barrel.

Cool I have ordered a tap and die 12m 0.8 single start to give it a shot. What size hole should I have for the tap and what size for the barrel?

Thanks

For tapping a metric M12x0.8 you need a bore of 11.13 mm or 0.4382" (formula D - ( 1.0825x pitch)
The male part is made to the nominal diameter, being 12.00 mm in your case.

Thank you I can see some more sleepless nights ahead lol
