Re: Gluing polycarbonate?

Hi Terry,

The epoxy will give some strength, and a good dielectric seal.  Of 
course nylon screws into threaded holes will give the best mechanical 
strength, and a method to clean or repair the inside of your 
polycarbonate form as well.  I have found that if the toroid is 
balanced on the secondary, and the whole assembly is not subjected to 
overly excessive sideways movements, that gravity holds things 
together well enough.

On a related note, I believe it was a posting by Richard Hull in 
which he stated that RTV produced acetic acid while curing, and that 
was fairly conductive and should be avoided.  He also stated that 
solvent welding the baffles was dangerous because of the trapped 
fumes, and if a spark were to be propagated inside the secondary, an 
explosion would ensue, destroying the secondary.
