Thank you for the thread!!. I was askin myself today about that..I didnt knew a thing..lookin forward to see this thread..
I wonder if this kind of pipe plug would work without altering the balance of the gun too much. With a small nut of course.
I believe McDonald Hardware has solid rubber plugs in multiple sizes that should work for your application without all the extra added hardware/weight. They are about 2 miles west of A1A on ST84 if you want to check them out.
A question to the pros; what's the best way to seal a speargun pipe? What kind of plugs, what kind of adhesive?
A related question; can a system for sealing aluminum pipes be inadequate for carbon pipes due to some kind of water permeation through the carbon fiber?
I am not a pro but I believe that there shouldn't be any problems with water permeating through the carbon fibers. The fibers should be completed saturated with resin leaving no room for water. I've used solid rubber lus before and although they are a b....tch to push in and remove it never required any adhesive to keep it in place as long as you have the right size. Interesting thread.
Old beuchats used a plug similar to the one Dan posted but it was made out of hard plastic and rubber. Using solid rubber plugs work but they are hard to push in when in the right size or leak water if they go in too easy. A friend of mine used to fabricate an aluminum slug with three o-rings inside grooves that would work perfect, maybe Tin Man can make one out of delrin or something??? I had good succes using a foam plug and then pouring G-FLEX epoxy over it about an inch thick and more if wanted to anchor something like a reel adapter.Hope this helps.
Dan, I use correctly sized NR (natural rubber) tapered plugs I use to get from Mcmaster Carr a while back. I put them in with a air ram jig and 3M 5200.

aimrite uses rubber stoppers (a very tight fit) .there is no need to worry about the amount of water that will enter threw the fibers it will never be measurable in the tube .thats just something engineers worry about, in the world of spearguns i have never found it to be a problem they just dont spend enuff time it the water

Get something like this.
You don't need any sealant.

Aimrite started doubble plugging my tubes because of the depths that I dive. Using a doubble plug and some 5200 will eliminate any problems that may occur from deep diving pressure.

Amen brother......I dive SO Deep my pneumatic cocks itself.

diving deep enuff to push in those plugs is is amazing ,i have put in a couple in the raw barrels i have gotten from rick , and it takes a lot of force just to get them in. thats a whole different problem than worrying about water migration around the cf fibers into the tube
