Yeh its just as bad here,ounce i tried to get a 100mm by 50mm reducer and it was $67!Hence all the small bore guns and no pistons.I hope all that stuff u brought is going to a good cannon because i would hate to see u waste all that cash on something that is more usefull as a oversized paper weight.

just curious, why would you build this big of a cannon if you cant shoot it over 30 psi, and don't have enough space to shoot it? not trying to be a jerk.

Well... because I don't care for shooting the cannons as much as I do for building them. The fun for me is really in the building stage, and being able to have a working finished product. Its kind of a bad thing, for it becomes VERY expensive when you constantly need to build more and more. Most of my cannons, I do not shoot 1,000 times like everyone else; I have had this cannon for about a month, and it probably has been fired under 50 times.

There is a farm about 1 hour away where I can really pump up my guns and go for the distance... that trip only happens around once a year though.

I like building huge beasts more, but I should probably restrict myself to small piston valved pneumatics; problem is, they still shoot too far... My midsize pneumatic launcher II was easily the most powerful gun I have ever built for its size... it goes off with a nice CRACK; really reminds me of a real gun; its pretty broken up right now, because I am replacing the piston.

i think your getting ripped-off,easy way to deal with price is either get a 100-80mm then a 80-50mm saves alot of money,and if you go to a plumbing merchant(sp?)go alone and make it like your spending alot of money so they give you it at trade price,my parts were gonna cost $180 but he gave it to me for $120 :twisted:

its going to be a really good cannon, 1.8mGB barrel,80mm piston, 1.2m of a 100mm chamber

for the guys in the US:
1.8m = 70"
1.2m = 47"
100mm = 3.9"
80mm = 3.1"

yeah, I understand , with a lot of my projects are built just for the fun of building. I mean, some of them are exceptions, (minibike, old dirtbike, potato cannon), but a lot of the fixing, restoring, and metalworking I do is just for the fun of doing it. :D
