I have the sdr21 1.5 in pipe sleeved into a sch 80 2" pipe that is 6.5 feet long. When I attatch it to the camlock that is on my chamber and pick the entire gun up it bows quite a bit there due to the barrel being so heavy. Do all barrels have this problem with bending at the camlocks? The design is almost exactly like Starman's with the burst stumps, but on his video it doesn't seem like his barrel is nearly as heavy as mine. Anyone else have this problem?

I think starman's barrel isn't sleeved. If it is then it's only partway down the barrel. That would keep it lighter and not bend the camlock so much. You could also make a barrel support somehow. Maybe a 4foot long piece of angle iron connected to the chamber with big hose clamps...

what material are your camlocks vinyl or aluminum? i have an sdr21 1.5" 6.5' barrel with aluminum camlocks and it is not sleeved at all. i have no bending whatsoever. I would have sleeved mine a little bit if i could have found sch but i was only gonna do mine about a foot down the barrel.

Depends on which barrel you are referring to. The one designed for Mr Morph is sleeved in sched 80 from the male camlock out to the muzzle. From the camlock to inside the chamber is the SDR21 only. There is zero opportunity to bend here.

The barrel and burst disk coupler I built for Triple Thunder...it is 6.5' and sleeved all the way with sched 80. It is rather heavy and has a small amount of give at the camlock with the plastic camlocks. The metal camlocks provided a much stiffer connection albeit with still a slight amount of give. If you turn the locks on the camlock North and South, you'll see more resistance to the barrel bowing.

However, even with the give that's noted here, it was still very functional in all cases. A 6.5' sleeved golfball barrel is rather weighty and will offer a LOT of leverage.

Yes, I am talking about trip thunder. So going with the metal ones will help, damn, those are so expensive.

not as bad as you might think

How small of a camlock can you buy?

McMaster sells them down to 1/2" and as high as 6".

Thanks 1/2" is the size I need.

Contra,

Most camlocks have a rubber gasket (of some thickness, I might add) in the female portion of the coupling.

This will cause at least some movement of any barrel.

I suggest some type of barrel support if the cannon is an over/under type, or just brace the barrel with your hand if it is inline.
