this seems like the place to ask..

the stock dilda driver was held to the heat sink with an "epoxy" that looked like a dark jb weld to me, and could be removed with a knife. it seemed more like jb weld than normal epoxy because I dont think I could have cut through epoxy that easily (I've tried cutting epoxy but it ended with 4 stitches in my thumb... thats another story though
would jb weld work for attaching the new driver to it or should I use some two part epoxy?
thx for any info

once I find my darn camera charger I'll post pics of my mod...

I did a test with some cheap speaker wire, made a little blob of jb weld and stuck two pieces of wire in it about 1/4" apart and it shows about 50M ohm resistance between the two wires... is that bad? haha..

well its far from good. if its producing a current then you are going to short out all sorts of things!

on my little trip to the store I bought some "super glue" brand instant set epoxy (two part) along with the jb weld (I needed jb anyways...)

god damn they mean it. it hardened before I could get the wires in properly (to test it for current)
I'm used to airplane (model) grade 5 minute that sets in 20 minutes... haha

Yeah, the JB weld has metal powder mixed w/ epoxy, it better for patching a cracked exhaust manifold.

Walmart sells something called "QuickSteel" (its in the automotive section) which works pretty well. Its a high temperature 2 part putty which you must kneed together with your fingers and then apply. Dries hard in about an hour.

you dont want to use anything that isn't water-based

Oh wait... you're talking about lasers here...
