what is the best repair method for a busted shell?

I’ve searched the boards and could not find anything definite concerning repairs so I thought I’d ask.

I purchased a shell that was damaged for $75.00 ( you really can’t complain for the price!), and I did check to ensure the seller was not a recaster either.

What I would like to ask folks with more experience with this is, What would you recommend repairing this with? I was thinking bondo and some sort of resin adhesive with some fiberglass strips on the inside to strengthen the area. But there is probably a much better way to repair this Here is a picture of what is damaged:

I’m new to building a pack from the ground up so I figured if I screw this up I’m only out 75.00 but would like this to turn out somewhat decent.

Thanks for any help, links, or topics you can point me to. I really do appreciate advice from all the veteran builders here.

That looks like a pretty easy fix. I would use a 2 part 5min cure liquid epoxy for gluing the piece together you can get Loctite brand at Home Depot for about 5 bucks. After you carefully glue it back together I would then line the crack from the inside of the shell with 2 part epoxy putty which you can also get at Home Depot for about 5 bucks. You could also use the putty to fill in any open cracks and broken resin. With the fix that should put you about 85$ :-). Hope that helps sir.

I knew someone would have a better repair method! Thanks :slight_smile:

I got the pack put back together (the epoxy is curing right now) but this is how it’s coming along, also thanks for the advice Chris that stuff worked great!

before I fitted the peice:

here’s how the peice fit after I placed it:

the inside with the epoxy curing. I mixed up some extra and spread it around the inside along the cracks to give it some extra strength:

And finally, at least for now the peice epoxied into place, I’ll post a picture when the epoxy has fully cured:

I still need to fill any little gaps and sand them down but I think this will be a fun build!
