wow i was going to do this when i completed my piston valve cannon with two 5' x4" tanks.......bad idea

i got 2.5 hours to go

i fly rc planes and i am sure a glow plug would easily work, however to obtain the best results ( this technique is used in rc jet turbies) take the glow fiament and pull it out of the plug so it is still connected, but is streched out.

Heres the movie on youtube enjoy!

sounds great, but you dont really need a braking system, because you can just tie a loop at the end of the ribbon, and loop it onto one of the pegs, that way, when the string runs out the barrel will spin to a stop, and you can just turn the motor off (btw, id be happy to take some of those drill mo...

Thanks for the help. Youll Be seeing mine on this site soon......

lol, it would be cool if you could rig a "top gun" style flip up switch- one for a saftey, and 1 as a trigger

here are some pics of the barrel in more detail

sounds like a good design, for th barrel I cut plywood into circles, and glued them together untill I had a cylender about 8 inches long, then, I drilled 8 holes for 1" poplar dowels to use for the individual barrels, after gluing them in , I cut more circles, and drilled them with the same hole pat...

Thanks!! btw, i recommend useing these http://www.uline.com/Product/ProductDetail.aspx?model=S-11490&root=&searchedkeywords=s-11490 rubberbands to anyone who is build one of these on the same scale as mine ( 5-7 feet long), they are very strong, powerful and cheap, they come in boxes of 180, I recco...

about 35-40, however, I do not reccommend loading that many, cause it takes forever, and puts lots ofstrain on the gun, I usually only load 500 rubberbands, which wil give you a good 10 seconds of firing time

Right now, im stiching a video together in adobe premire elements, these things take awhile to video tape, because it takes about 1 hour to load 1500 rubberbands

Here's how it works: (sorry, the first picture is at the bottom of the post) Loading: 1. ribbon is loaded onto a spool, which is chucked in a small drill. 2. the ribbon is attached to one of the pegs on the barrel, and than is inserted into each slit in the pegs 3.rubber band is loaded over peg 4. r...

i cant get it to upload, so i guess the only way to get it on here is to first put it on youtube

I ripped it from the video im trying to upload right now, but im having trouble uploading it, if you dont believe that thats real, I suggest that you seach youtube, and google, and try to fingd a video with that in it.

i live in hudson
