Well, as it turns out, I managed to get all the parts I needed before the end of the day. Called my friend (who happens to be the retired city engineer) and he hooked me up with some scrap pipe and fittings. I forget the type of tubing (huge alpha numeric name), but he said it would take 200psi no p...

I apologize for the triple post, but would this strengthen the chamber enough to withstand temporary use (Just for the fourth)? 4" to 4" fittings end to end. Would the double layer give the chamber enough guts to withstand 20-30 shots? Until I can get to a large store on Monday. http://img.photobuck...

Got smart and called rather than burn my gas... Strikes on both. And I live in the largest town in the county. Heh

Have a farm supply just 2 miles from me. We'll see what they've got. Thanks :thumbup:

Tried every building supplies store in town (small town) and no one carries pressure rated pipe larger than 3". Unless sewer pipe is pressure rated. The guy who worked there couldn't give me an answer. And no one carries ANY abs pipe, period. Looks like I'm out of luck until I can drive up to Tulsa...

Says PVC-DWV on the side of the pipe... So I assume its PVC?

Hey guys, I just finished building my second spud gun today (has not been fired), but am having some doubts how safe it actually is. After some prodding from the guy at Lowes, I wound up buying non-pressure rated 4" cellcore for the chamber. Lowes guy was convinced the gun wouldn't develop enough pr...

Took a still frame from the video and had to say... this looks really cool.. lol

Correct, the local stores didn't have a reducer to go strait from 4" to 1.5".

Your lucky, if I fired my big cannon I'd probably get arrested (against the law in San Joaquin county..) No worries about that here... in fact... the FBI agent up the street shoots his off his back porch :lol: Deffinatly a consistant gun. It even makes pretty tight groups up too about 100yds. And w...

Got really bored one day and decided to build a spud gun. I think it works pretty good for a first try. Barrel could be longer, but it still works pretty well. 1.5" barrel... 3-4" chamber. Aqua Net hairspray... Barbecue sparker. Nothing special but its great fun. http://www.youtube.com/watch?v=PpQqw...
