Gluing 101, I'm failing

[runzwithsizorz]

Have fabricated, (in my mind), a wet well using a piece of Cpvc, and a large rod boot. How should I secure it in place? I have a hot glue gun, Z-poxy, silicone adhesive, and CA. Something I regret not having now, is an
accelerator, such as zip kicker. There are times when you just can't use clamps, or weights. Can fast setting CA be mixed with epoxy? Which is a stronger bond? Can I secure with hot glue, and firm up with epoxy?

It's OK to "tack" pieces in place with CA, then finish up with Epoxy resin & fiberglass cloth. Done it many times myself. But don't get CA on PVC - it will weaken the plastic and make it brittle & EZ to break. Made that mistake building a PVC boat stand once - a little pressure & SNAP!!! Not sure, but it may have the same reaction on Vinyl ester resin - maybe someone can chime in here with their thoughts.

I am a plumbing, and landscape contractor, and ONCE, in a pinch, I used Ca on pvc, seemed to work fine. mind you, it was in an inaccessible, low pressure arena. I really don't want to, nor feel the need to fiberglass this in, it will also be underneath a radio box.
Perhaps a pic would better explain: HPNX0279.JPG

Why not try Gorilla Glue. Save on plastic and rubber. Just fixed the transom on wife boat with it and no problem

Thanks for the "welcome back". As a hospital corpsman, I spent my year in Viet Nam with 2/9 3rd Marine Division. AKA: Hell in a Helmet. Did my best not to get hit, but a mortar finally caught up with me in the DMZ. Nothing serious. JIM

You forgot to add an exclamation point, or two, But, ummm, yah, I got it. Clean, clear, concise, and to the point, with absolutely no chance of me running to mommy, and telling her that you're unsure.
Seriously considering using my hot glue gun. I can glob it on thick, it won't run, and it sets in mere moments. It will bond to the fiberglass, and to the wood transom, however, not sure if it will bond to the
cpvc pipe. Perhaps scuffing, and using a primer would help??

here is my take on it.............
first off on the rubber boot, use a zip tie to keep it in place.
the rubber WILL go south for the winter and have to be replaced one day, so why not make it easy to do it.

the PVC CAN be held in place using Marine Goop. rough up the PVC clean it with alcohol real good set it in
place smear the stuff in place where you need it, use spit (yes, spit. won't stick to it. I know, YUCK!!!) on your fingers to smear it around and let it dry.
then after it all dries up, then yo ucan go ahead and epoxy/glass the rest of the tube to the hull bottom.

The reason I am using the 1/2" *C*pvc pipe is it's outside diameter is much less than the 1/2" pvc. 1/2" copper also has the same outside diameter, but for some reason it is a lot more difficult
to side the boot in place, and when it comes to replacing the boot, I really don't want to have a big struggle. Also again, securing copper could possibly bring up another can of worms.
Way ahead of you on the zip ties, or clamps Carl, I'm not a complete idiot, mostly, but not complete. However, if you could see, and feel this, you would have to wonder, whats the point, it fits that well !
Something that even you may not have thought about Carl, in order to facilitate the replacement of the boot, the forward edge of the wet well will have to be elevated, which, in turn, will lift the whole
tube off the bottom. This, actually, is the easy part. I will fashion a wooden chock/support, might even be able to screw down a pipe clamp, Hmmmm. I will be adding a layer of CF near, and around but
not under this installation. I have NO intention of glassing this in, making it near impossible to replace, redesign, or gasp, eliminate. Wouldn't marine goop be too thin, too flexible, and take too long to set/dry?

Have been experimenting with my hot glue gun, gluing pieces of pipe to wood. Seems to working ok, so far. The beauty of this, is it's fairly easy to remove, unlike epoxy. Also some silicone based adhesives allow
too much play/movement, which can break the bond, and pull away, (i.e. I start jiggling the pipe around to replace the boot, or grease the shaft).
