SpudFiles

just entered my B.M.F. cannon in the contest. if anyone has any questions or comments post here or pm me. hope you guys enjoy. forgot to mention in the contest that this is my first pneumatic and i learned all the theorys from you members here on spudfiles. so thanks to all. scatdawg

Nice gun. How did you make all the metal parts?

thanks. my occupation is a cnc machinist. ive worked thru my lunch hours for the last week and a half making this cannon.

DAMN........that is effing nice dude...wow that is pimp shit@@ its coaxial right?? jesus dude i have to say that is the best ever coaxial ( if its coaxial) penuamtic i have ever seen...and its up there with the best handheld pneuamtics...all i can say is damn..

I am very jealous, I only have lathes and mills that are probaly older than 40 years. But I guess its a learning process. So whats the RPG looking round for?

very nice gun, i assume that you fill it through the valve, if so how well does that work?

cnc machinest....i think your my best friend....

EDIT: eh, maybe i should read the cannon submission, wouldnt want to look like an idiot

*i asked a question that was answered in the actual submission, silly me*

Wow, let me say, tha is a nice a$$ cannon, good luck in the contest, as to everyone else. but i gotta say i love the paint job, looks lik a nice and cleanly constructed gun

Just one more question, how did you machine the inside of your barrel? I know on a lathe you can use a reamer, a nice drill bit, or a boring bar but as for a CNC machine is it the same?

thanks for all the props. it does fill thru the valve. it is a coaxial. the qev is just unbelievable on this cannon. the piston is made of uhmw plastic with two orings. .005 clearance. rubber flap covers the equilization holes. the foam decreases pilot volume. the wood was just a sleeve for the airgun for aesthetics. the rpg is just a muzzle loader bar to load the corks.

the barrel is a standard size aluminum tube. not pipe so it has no seams inside. perfectly extruded .800 inside diameter. the bullets i made were rifled since my lath doesnt have enough travel to run a rifling tool thru th barrel. the longest barrel i could rifle would be about eight inches.

Ok sounds good, nice work again. I am a fan of machined parts.

looks good altogether but i tihnk ur going jsut a bit overkill on actuating it witha qev and a modded blowgun..now dont get me wrong it looks good but for a small cannon i cant really say that the qev increases the power that much...i know it does but im jsut saying a 1/2 or 3/4 ball valve would proabbaly do the same..almost...i =still lurve ur cannon though

Very nice,clean cut and beautiful.As with Shownomercy I am jealous.My lathe was made in the 30's,I'm a litttle outdated.The RPG ramrod was a good idea,it compliments the gun very well.And know it is time for the Noob question:how powerful is it? I would lke to see some damage pics when available.

And how long does it take to machine each bullet?
