Step 2: Cut the plastic where it widens, then dremel it out until the plunger tubes entrance is as big as it's exit. Pic is of midway dremeling
Step 3: A CPVC coupler gets wide in the middle, and skinnier at the ends. So cut the CPVC coupler in half and bore out one of the halves so CPVC can slide smoothly through it. Glue in a piece of CPVC in the coulpler, so that nothing sticks out on the part that used to be the end. Put some glue on the end of the coupler with the glued in barrel, and push it as far as you can down the plunger tube.
Step 4: Make this
Step 5: Reassembly. Cock the gun without the plunger tube, then slide the plunger tube on. Don't forget to lube it up before you do this. DO NOT put the Extension spring back in place, it makes the trigger pull huge and puts unnecessary stress on the barrel.
What it should look like:
And now put step 4 on with glue:
And you're Done.
Ranges: About 40 ft., without step 4: 55 Ft.
A fun gun to modify, but definitely not war worthy.

Dunno about your glue problem, but try making the segment of PVC coming off of the PT shorter, which will make the barrel assembly closer to the gun, decrease dead space, and give you much better ranges.
I was going to do that, but now it's broken. I think I am going to glue the CPVC back in and drill a small hole through the plunger tube and coupler, then put in a metal rod. Or maybe I should put the rod in before the coupler and it will take the full force of the spring. Either way, I think the plunger tube will crack beyond repair after awhile if
I do either, so if anyone can recommend a glue that can take the full force of a spring, post here.

BUMP. Does no one here except Tantumbull know anything about how to fix this? I would also like some input on my rod idea.
Have you tried my method yet?

You could always try drilling in two screws, one per side of the shell, into the cpvc. That would likely keep it from shooting out again.
The CPVC didn't actually shoot out, the seal between the plunger and the barrel (which was made of hot glue) broke, so all the air just ran out the path off least resistance, which sadly was not the barrel.
