couldn't you use some fiberglass cloth? They sell the woven kind in the autobody department of autoshops and home improvment stores... Seems like a layer or 2 of that on both sides shoud hold up pretty well...

I can see fiberglass flexing just as much if not more than mdf. the only thing I can think of for this to work is like 1" thick polycarb with space machined out for the coils. Could you add a steel or iron plate to the outside of the coils, so that it may condense the flux to the interior?

How about this, make the coils a lil bigger(dia), use steel plates between the coils(might want to slot them), then put a piece of U shape support in it on the edge. as long as the the support dont' concentrate the flux, it should shoot fine.
Might loose eff. due to poor coupling tho...

Well here's a pic of the destroyed coil...it deformed or I'd just glue the coils back down to the wood:

What about weaving the coils through some fibreglass cloth and then impregnating the whole thing with lots of CA glue?

CA glue need OH- to dry/harden....blahblahblah
so a big chunk won't harden like resin/2part epoxy.

I like the fiberglass idea...since I'm already using epoxy it wouldn't be a big change and would probably add a lot of strength...now where can I get some? Home Depot doesn't have any, though they did at one time.
