I bought 20 grams of Pascofix glue along a bottle of Pasco-fill at the Toledo show from a German lady. They said it would bond almost anything to anything, glass to metal, rubber to glass, etc, etc.
I've used the combination glue and fill to make a beam mount to replace the radial mount for an electric motor out of 5 ply and it could not be broken by hand. Then when I drilled a hole off center, again I used the combination to fill the hole. Within a few seconds, I can sand and drill another hole, no worry about the drill bit wondering off. Curious, I tried it several times. It worked every time.
I compared this glue to the familiar CA we've come to love. I glued aluminum to aluminum. The Pascofix held within a minute, no need for a 2nd spray. The CA had to be sprayed with accelerator, but after a half hour it came apart with a slight twist. (Maybe I got bad CA?)
The beam motor mount alone more than paid back the price of the glue and fill of $37. I had the same mount custom made out of tempered aluminum, and it cost $50.
Here is their web site, but since I could not find prices, I may have to order much more than I could afford;
