moar penguns.

Unread postAuthor: inonickname » Sun May 17, 2009 7:18 am

Well I was bored today. Decided to have another crack at a pen gun. Thought I'd do something relatively new, taking inspiration from Jook's stock tutorial. I carved a stock from balsa, stained it with coffee then did a ridiculous number of clear coats until it was all smooth and strong. Still extremely light.

The shock pump clears the stock by 1-2mm, which is nice.

....But in continuance with my pen gun tradition it doesn't work. Rubber piston cut from the bottom of a stool doesn't seal full stop. If anyone actually has good suggestions for rubber (thick enough to cut a piston from, or very reliable) I'd like to hear them. (seriously).

Me and dad are heading up to Perth next weekend (sexpo anyone? narr..) so I'll get my pipe bender back from Matt and buy some telescoping tubes. I swear to god I'll make a proper pen gun work someday.

Sorry for the average photos, but they're quite respectable for the camera I had on me.

I'll update when I get the bloody thing to work. Considering soldering the schrader in so I can melt it and replace the piston if it fails, then epoxy it when I get it right. We'll see.

What do you guys reckon? Any advice? Op pressure (when it works) will be 300-400 psi btw.

Anyway, looks great... best of luck with getting it to work. It'd be a shame if it didn't.

From the looks of the photos you need to find the macro button on your camera. Makes for clear close up pictures :D

Pfft. I have a Kodak C130.. It has the following modes:
Off
Auto
Video
Favorites

It's a piece of rubbish. But I promise to get some shots with the better camera when it runs.

Thanks for the tip Carl, we probably won't be around Padbury (dad doesn't like mum's grandma much..and that's pretty much the only reason we'd be going there) but I'll definitely try clark rubber.

Thanks guys

Thanks for the offer man! I'll just buy some rubber though. Costs bugger all and then I have as many pistons as required. Thanks though :D

As for the stock, it's pretty simple. I based it on Jook's stock, but carved it out of balsa. To be honest, it probably took me 15 minutes to get it completely done because balsa is such a workable material. (not counting staining and clear coat time)

Cure huh? For what? Is this gun working now? Did somebody come down with an incurable bout of flu? What what what!?!?!

I can't wait to see somebody on the street with a pengun. May take several years, though.

I never leave the forums! A dvorak pattern keyboard eliminates small typing errors and allows for one-handed surfing!

(Kidding, of course. :P )
