maybe you could launch me a couple coconuts to me here in CA. just kidding, looks like it could though. really nice clear chamber/barrel.

Noice launcher!

Very nice build, surprised you could get those specialty components in Hawaii. Especially at the price you mentioned. All the solvent welded, and threaded connections look really nice as well. Hidden wiring is nicely done likewise.

Where the handle meets the chamber in two places, did you drill a hole in the side of the chamber fitting, or just sand those fittings really good to the curvature of the chamber?

This might be repetitive in nature, but nice launcher. Also this mentioned GBMG launcher will be a thing to see. Good luck.

Good god, I love how you did the handle! Clear chambers earn an A+ as well.

That is a nice cannon, I like it.

I also second the motion for a coconut launcher. All in favor say aye.

Lastly, i was going to congratulate you on speling Hawaiian correctly, then I realized you are *from* Hawaii. I really don't meet many people who can spell it correctly. There's a tanning parlor around here called "Hawiian Tan". I thought, if you're gonna have a business, at least spell it right.

aye aye aye!!! i wonder how big of a barrel you would need for a coconut. that would be a fun project. if it wasnt 50 degrees and coconuts werent so expensive here i would build one. id probably need a 4 inch or 6 inch barrel.

VERY Nice build! I like it.

I do have a few suggestions though. To help keep your nice, pretty, not-that-easy-to-replace clear chamber from getting scratched, you might want to make up some wooden saddles for the handle and propane tank. Acrylic saddles would look good on this cannon as well, if not better. Also, see if you can locate some Plasti-dip for your hose clamps. A soft rubber surface is much better for your chamber than stainless steel.

As for the small chips in the paint, scratches, and other sighs of general wear and tear, there's no shame in that! It simply shows that you've gotten some fun out of the cannon! :D

Grade-A build job. I wish I could buy some clear pipe at that price. But the overall appearance of your gun is extremely professional. Keep the cannons coming.
