Your power issue is probably due to the size of that chamber(its pretty small) if you ever decide to make another I would suggest bigger chamber and barrel. But still very nice work nice to see alternatives to pvc and abs.

thanks guys, but for some reason, every time i shoot it, it gets more powerful, i fired it a couple times today, and the pellet bounced off my across-the-street neighbors garage with enough energy left to bounce half-way back across the street, so previous power assumptions are... i don't know, but it seems pretty strong for the inadequate C:B ratio, it's inaccurate, but if you got hit it'd probably sting pretty bad

Could you bring some numbers or a calculation with you?

Being the spray-and-pray that it is, you'll probably get wide swings in performance especially with the relatively small chamber you have there...just hard to nail the right amount of fuel each time.

I still like it...any burning wood smell yet?.. :wink:

it's a combination of wood and static gaurd, so it's quite an interesting smell

Could you define "interesting"?
