hello everyones i went off and built the thingy. i didnt use any wood though, basicly a 24 inch iron pipe with 3mm walls, 3/4 inch bore. i've fired it and it seems to work fine. i used some black powder i dug out of a roman candle so i didnt get very good burn  i fired a tape wrapped marble about 15-20 feet using around 1 and half soopssthingys of the powder. i used a 3/16 inch hole on the top of a cap on the back to feed in my fuse, which was a dollar a dozen party sparkler. looks great when it goes off ;D I'll be trying again soon with proper black powder |
