Simple Question I Just Haven't Been Able To Get An Answer To

Unread postAuthor: Foxx » Thu Jun 25, 2009 8:59 am

Hey guys, I know this is a really basic/probably stupid question, but can someone here explain to me exactly what is a co-axial and how it works/how to make one? (Yes, I have searched, and no, I didn't find a satisfactory answer)

Thanks

The third animation is a co-axial.

What "sets it apart" is that the barrel runs through the entire chamber.

The actual definition of coaxial is two cylinders on the same axis. The chamber is outside the barrel. The most common configuration is a piston in the breech with the barrel inside the chamber to the piston at the breech. The term comes from the electronics industry where a cable has one conductor inside the other one.

A coaxial cable has an outer conductor on the same axis as the center conductor.

Why do all the words in the title of this thread have a capital letter?

Looks like it needs an acronym... SQIJHBATGAAT.......

Actually there was a thread about a year ago on making better posts, and it instructed to use cap.s...It was a good usefull post, (Link? can't find it now???), About writing cannon specs, getting more views etc.
I always capitalize each word in a post since I read it. :roll: 8)

BTW, for pneumatics aren't co-axial the most efficient(???)
I just like them because of the "Bullpup" configuration I'm fond of.
Also been thinking about them because all the dang brass "T"'s I find are cast. Course I did see smaller diameter cast fittings on a helium tank recently.
Besides all the local brass nipple pipe only goes to 3/4" so my chamber would be too small. Guess I'll stick with my cast brass "T"...
EDIT:Found it I think Great posting info too.
I thought it was a sticky. Should be added to the "rules" IMO.
Where the heck is MrC.??? If I don't find out soon I will probably flip out!!!
PM me someone.... :evil:
EDIT2: No that's not the exact thread (??? where???)...
