My son broke his rockband drumset. I would like to try and repair it. What is a good plastic epoxy?
 
PC7 or JB Weld will fix it better than new.I prefer the PC7,it's drier which makes it harder to mix but it stays where you put it.
 
IMO there is less variation in performance between brands than there is between types. Epoxy resin chemistry is pretty well understood. For the most part there aren't any great secrets in formulating the commercial adhesives that are commonly found in hardware stores.

There's three main types of epoxy adhesive sold in most hardware stores.
--5-minute
--High strength (Takes a couple of hours to cure)
--epoxy putty

--Use the 5-minute if the configuration is such that you cannot clamp it and leave it alone for a couple of hours.
--Use the high strength if you can clamp it.
--Use an epoxy putty if there is a gap to fill.

Might I ask what type of damage you are trying to repair? Are you sure that epoxy is the correct type of adhesive?

Bond configuration is at least as important as the adhesive used.
The diagrams on the page below show configurations that should be avoided.

The left most drum pad broke off. I'm not sure it can be repaired, but thought I may try before dropping $80 on a new one.
 
I don't know much about drums. I don't know what the drum pad is or what it is made of. If the pad is non-structural and made of rubber, you would be better off with rubber cement than epoxy. Epoxy does not bond well to most rubber.
 
This portion is plastic. The rubber part is on top and not effected.
 
Epoxy should work then. Take some medium grit sandpaper and roughen the surface of the plastic prior to applying the epoxy.
 
Rather than just gluing the piece back on, knowing the design is pretty weak, I would personally recommend taking it apart and adding some support structure out of metal tube or something. A straight glue job will be prone to breaking at the edge of the joint.

I have thought about this. I think I'll try to pick up some metal to use for support. I am not going to spend $79 to replace it. One, they broke it by abusing it and two I work to hard for my money. If I cant fix it they will have to do without. Could be a good life lesson for them.
 
I use the 5 min stuff.
I have had no trouble with it at all and it is very strong.Just make sure what ever brand you buy has both parts clear.I have gotten some that the resin on one side is a yellowish color and it was hit or miss on curing.Must be something to due with the whether when used.Last I used it it never set and I tossed it in the trash,used the other and it set perfect.
