The steel construction is worth it to me and probly to others as well, at least for the peace of mind. If you drop a PVC gun, you risk it failing from a friggin crack, sunlight etc. Most of all, I like the professional build quality that is to come of it. Custom structure definition and no loose end...

A glimpse of whats coming

Hi, This is my new design. Its nearing completion but is still a work in progress. I can't decide if the first version will be stainless or painted steel. I would love stainless, but it all depends on how much my buddy quotes me. Current barrel shown is a .8:1 C:B ratio. I wasn't going to post yet, ...

design question

Do you lose a lot of power when going from, say, a 4" chamber to a 2" U-bend, and then lets say you step down to 1.5" and then your barrel is 2". Does that smaller 1.5" diameter section between your chamber and your barrel constrict or bottleneck the airflow? I was thinking it shouldn't be THAT big ...

In alot of cases keeping your C:B around .8 will serve you best. It should give you great velocity and quiet down the beast. I have a 45" barrel for a 1.5:1 ratio and a 75" for a .9:1 ratio. In all honesty, the 75" barrel performs better and is alot quieter. It might differ for you like it does wit...

Yeah, sure, but you'll have to hop back in time and post it somewhere over a year and a half ago, destroying the continuity of time, etc, etc. Contest is long since over. Damn, how rediculous of me. Spudblaster15, his chamber cracked. Solid wall ABS? Damn. What happened there? Maybe PLASTIC isn't t...

Re: New barrel advice

His secondary question: About the ratio, from what i've read 1.5:1 is optimal, going with .8:1 seems to be too little. Won't the spud drag at the end of the barrel? He's worried about "spud drag"... Yes, spud drag is not good. However, unreasonably loud noise isn't good either, and since actual sil...

Re: Quick question

Wouldn't it be better to sharpen the inside of a barrel end to create a more tight fitting spud? Indeed, it's known as a double chamfer muzzle knife. You can see it being put into practise on Burnt Latke here. Like you say however, it needs to be done fairly shallow. Thanks for the response. Just a...

Quick question

Wouldn't it be better to sharpen the inside of a barrel end to create a more tight fitting spud? Or would it end up being too tight and you'd have to make the chamfer super shallow....?

I'm afraid to mention because I don't want to start conflict. Its not my goal, so its irrelevant. What is relevant is that the information has been presented to me and beyond that, it makes sense, at least to me. 1.5:1 just sounds right to me right off the bat, but 0.8:1 has intrigued me enough to w...

Well this is a combustion cannon. Sorry if I lost you there, but I am more than willing to check out info I have missed about C:B ratio. I want the best power of course, just with a silenced barrel. I guess I am confused because information differs bewteen two diffrent spud gun sites. I assume both ...

If you really want to exchange your barrel why not try to get the true optimum(sp?) ratio of 0.8:1, But i guess 1 is close eanoth, sounds good, oh and are you sure you do not want a loud band, dumb question but many people really like that! Yeah I love the loud bang actually. But living in the damn...

New barrel advice

I am making a silenced barrel. My chamber is 4" SCH40 x 17" long. I currently have a 1.5:1 C:B: ratio with a 43" long, 2" SCH40 barrel, and its LOUD. I was thinking about lengthening the barrel to 60", making it closer to 1:1 and having the last 17" of barrel the silenced part, using 4" SCH40 as the...

PVC isn't tempered glass... Last half a dozen pvc failures I've seen posted here consisted of fairly sizeable bits. I wouldn't run out a generalisation on hearing of one incident. But it would be nice to see a deliberate cellular core ABS failure. Might require a hybrid mix or perhaps a pneumatic o...
