The last inch or so of the plunger shaft of my sm1500 has broken off and I can't seem to make a permanent fix. Does anyone know what the best thing to attach it back on with is?

The best solution would be to slap some plumbers goop on for a day or two then wrap it in some electrical tape. Or you could just substitute the plumbers goop for hot glue.

Oh, don't forget about beautiful, beautiful epoxy. 1500 psi. Any questions?

Super glue. It dries faster, is easier to work with and seems to work a little better with plastics and perminent bonds. Goop is useless, epoxy is overkill.

Here's my 2 cents

Hot glue is worthless, except for making darts

Super glue is next as far as weakness. It's good to for a quick bond, but chances are it will snap with a little pressure, so i recommend super gluing first to get it together, then....

plumbers goop is my go to glue, however if possible

2 Part "platic weld" epoxy. It's this ugly yellow color and it smells awful, but i swear to god it hold ANYTHING plactic. Takes like 48 hours to setup as well.

Also, I've heard good things about gorilla glue and elmer's version of the same glue. I used the elmer's version on my PoS homemade, and that thing held real good.

in conclusion super glue -> goop or expoxy -> go

Yeah, I've been trying to keep this thing together for a few months and super glue, hot glue, and plummers goop all seemed disconnect after a few hundred pumps. I guess I'll go pick up some of that epoxy because overkill is my goal here. Thanks everybody!

Here is what I would do if you can't get it to stay. First I would get some epoxy if nothing else is working and do that. If I recall, the 1500's splunger shaft it an X. After letting the epoxy dry, I would take four small metal rods and hot glue or goop them onto the shaft as a splint. Then, I'd wrap the whole thing in some duct tape so seal the deal.
But since you added to the plunger shaft, it will no longer be able to fit out of the gun shell when pulled back. Just take your trusty power drill and make the whol bigger. Hope this helps, if its unclear, just say so and I will try to explain better, or get some pics.

When getting epoxy (if you choose to use it) get the welders epoxy or something that takes a while to set up. I've found the the 30 second epoxy and instant epoxies usually don't hold up at all, or are about the same strenth as hot glue.
