Hi guys! Long time no post! This one made me chuckle, but I do so love lung-powered blowguns that I just had to chime in! I once blew a needle dart halfway through my pointer finger wondering if I could hold my finger on the end of the barrel, blow to full pressure, and then whip my finger away quic...

I'm imagining that the stiff rod pushes the golf-ball from go to whoa, ...but how about a heavy piston like a hammer-face on the rod that doesn't contact the golf ball until the last few inches of it's stroke so that the elasticity of the ball is utilised? Be wary of the forces involved, having a he...

Shit! Good point! It appears to be getting through to the normal exit port either between the steel shank and the rubber washer, OR, between the rubber washer and the plastic sleeve with the transverse hole in it. I spun up a brass replacement sleeve, fail. chamfered the brass replacement sleeve and...

My blowgun leaks...:(
Does anyone know how to mod a blowgun to stop it leaking? Yes, I searched and wiki'ed (...that took an extra hour mostly trapped in the humour section... :lol: ) but only found that others have had no probs up to 400psi!?! My three all leak at +/-200psi (Just had a lend of a 300psi shock pump! :P ) ...

JSR, that's awesome! 400+fps is QUICK! (...for an arrow...) Here is my new home-made stabilizer made out of busted carbon-fibre arrows and some old bits of nylon/delrin. Can anyone tell I'm a cheap-skate? Why pay $130 for a great-looking brand new one when you can make one out of broken stuff that l...

An ode to the 82nd Airborne: "I shot my Bowtech at the sky, ...for the life of me, I can't think why... Instead of watching parabolic grace, I lost my shaft in outer space..." Here is a home-made bowpress! My new 82nd Airborne by Bowtech delivers 333 feet per second with a 343 grain arrow! About 84....

I laugh, because: "I have just consumed an entire bottle of port" and "I have just consumed the entire harbour" are significantly different... I give respect for the fact that a new level of understanding for the acceleration of projectiles has been reached. 8) Word. Cheers! JoergS! )Edit( these two...

Sie sind zweifellos an der vordersten Reihe der Schleuder-Entwicklungstechnologie. Das einzige Ding, das ich denken kann, um zu schreiben, besteht darin, dass ich pflegte, zwei Schichten von dünnen Bändern zu verwenden, um meine Schleudern anzutreiben.
