This particular situation there is very little torque/force applied to the wafer. Some rotatory switches have fingers that pinch the rotor where these glide over the top of them. That's the good news. It means alignment is somewhat critical. If the wafer is pitched away from the stator it could yield poor connections.
When I bought it I didn't buy it for this job. I was out on one of my few outings and seemed like a good thing to have in my tool box. The strength between the two 6hr and 24hr set time far exceeded what I thought I would need, wasn't trying to repair an engine block or cylinder head. So it was just a matter of picking between 6 or 24 hr and that was a no brainier.
I talked with Kirk about the 6hr set and he told me that he tried it and it never set up at all. That was a little bothersome! That's why I did a trial run just to be sure it would harden. Did google and read posts on arf. It didn't have glowing reviews. But for now I'd give it a [Image: https://philcoradio.com/phorum/images/sm...humbup.gif]
I don't think I've used epoxy to repair Bakelite. Mostly cyanoacrylate and fiberglass/resin/bondo. Sometimes aluminum backing although it makes the repair kinda thick on the inside. But SG is a mystery. Sometimes you put it on and it works great. Other times it stays wet never dries or it runs all over the place glues things you don't want glued. It's 50/50 gamble and didn't want to take the risk on the bandswitch.
I know all yous guys like pics so here's one of the bs all wired up and working.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got it!
