glueing breadboard together
Any one tried laminating two layers of bread board together with locktight...Im' trying it now...but I remember a washer being stuck very strongly to it once. Will see what happens in a few hours _________________ Miles Blow - Julie Pitts

Chipboard screws do a good job.
Weldon is supposed to be good, but I have never tried it. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

I'd use Sikaflex, it's a flexible poly urethane that is really good as an adhesive and yet has lots of strength without being brittle. I'd use it over the super expensive loctite glues _________________ https://www.halfdonethings.com/

Absolutely, Sikaflex construction glue is awesome! Just make sure to get the urethane variety, not the cheaper acrylic stuff. Don't let it dry on your skin, its very difficult to get it off!

Cool....though i think $1 hobby king red thread lock is pretty strong....i think it melts the two together slightly.

Sikaflex is THE glue to end them all seriously lol. A friend glued diamond tread aluminium to a metal frame for a dyno and had to cut it off with an angle grinder when he did it all wrong. Crazy strong stuff. _________________ www.demon50s.com - Minimoto parts

I'm currently using Sikaflex for engine mounts on my MR2 after this happened to 3 out of 4 mounts when I went to the drags

Sorry to hear that, the Sika glue I used to hold structural house parts together is callled "Maxbond 30 minute" You need to hold the parts together for at least 15 minutes, but after that, you will need to use saw to cut them apart! It foams a bit, so don't use it near edges you want to keep clean. So far it has worked for wood, concrete and aluminium.

Our recently installed bathroom mirror fell off the wall when we were smashing tiles out of the floor today. Luckily it didn't break, because it fell a short distance to hit the top of the nice new very expensive vanity that we had custom made, and put a big dent in that, and was still attached to the wall on one side.
It was held up with two full length strips of double sided mirror mounting tape, and a whole tube of similarly mirror-approriate glazing silicone.
When it goes back up, I'm going to coat the whole back of it in Sikaflex. _________________ <Patrician|Away> what does your robot do, sam

That's very timely info - I was going to stick up a mirror with silicone, which is always the 'go-to' adhesive on info sheets and renovator sites. Which side did the adhesive let go of, mirror or wall? Was there even a slight chance that surface was oily?

the silicone let go of the mirror side. The double sided 'mirror' tape let go mostly of the painted wall - but didnt take any paint with it.
Both surfaces were cleaned, the wall with dry paper towel, the mirror backing with windex and paper towel.
To be fair we were shaking the shitbags out of the very unstable pole-mounted house we have, so its really a worst-case sort of thing _________________ <Patrician|Away> what does your robot do, sam

LOL, I don't dare ask how you were shaking the house so much - will there be a mini-Jaemus next spring? It sounds like plain bad luck with both sides of the bond giving up like that. I would roughen up the paint as much as possible - the Max-Bond urethane I have used has insane sticking power on porous surfaces, not quite so much on polished surfaces.
