My first post here!



I made these back 2002-2003 (before video camera or Chrony), not a lot to go on, just knew that it was possible. Hand tools and a drill. Epoxy. Scrap.

Only the blue one is still functional. It fires 12g CO2 caplets by piercing them.

THe others, from top:

Spruce Goose, square reservoir coax 1/2" bore. Snappy while it lasted. Trigger acts directly on pilot valve.

Bullpup coax, 1/2". At 160psi it would break through 2 by 6 lumber. Trigger is a remote pilot valve.

3/4" ball valve in-line, the bottom tube holds a spring powered hammer that whacks open the valve. Weaker than expected.

First build ever, a hammer valve 1/2" barrel. Valve body made of wood. At 100 psi it would pierce 3/4" wood with roundball and have a second shot left (didn't expect that)

I have learned a lot here and hope to build more soon!

Looks like an IRA weapons dump

Welcome to the forum

square reservoir

Big no-no, don't put pressure in a flat sided chamber!

Looks like somebody's ready for the zombie apocalypse!!

the blue one looks really nice, may i copy it ? i think i'll make it shoot AAA batteries

Bravo, please do. At some point I can get a better pic... I wanted to chrony that one anyway

JSM, on the square tubing, I agree. I was trying to get more air storage without adding height or width to the launcher, but after reading about aluminum and pressure cycles I wasn't too sad when it developed a leak. Better off using stronger round tubing and increasing pressure, though back then I didn't see a way to do that.

Nice work.

The wood work looks awesome!

Seems to be a sudden influx of Canuks about....nice to see.

Well I'm here now, it must be in the air

Apparently this t-shirt launcher I serviced is used for national peewee hockey games...
