Liquid Metal

Devcon.. its aircraft rated.... well some of the range is.


one thing not yet mentioned is you MUST protect the devcon (jb weld, loctite liquid metal) once its set. on some metals it will encourage rust to form at the "joint" of the devcon and the parent metal, once the rust creeps in far enough it will either leak or come apart.

If its to seal up on the cooling system and if its not structural you can get away with normal epoxy.

Devcon, as said make great epoxies, and I've just started using JB Weld on some saw stuff as it has a higher operating temp than Devcon.

Note that for any epoxy to work successfully you need the parent metals etched and scrupulously clean, which means repeated cleaning with isopropyl alcohol or methyl ethyl ketone (nasty stuff and a carcinogen)

where are you using it on your saws? what temp are you expecting to see? I have read that the crankcase will only see about 150c max??? I have also been told that JB doesnt like alcohol....A few of our USA friends think Devcon is better than JB. I am leading towards devcon for the full circle crank, unless I can be sure that foam/carbon glass and expoy resin will be fine???

Yes I found all the small cuts and nicks in my fingers when I used MEK
Is MEK a good etch'r for steel also?

I used it on the carby and I was going to use it on the transfers.

One of the blokes on the old RS site was using Belzona (I have the numbers of which one somewhere)
He reckoned it was better than JB for building/making new transfers and boost ports.

Devcon was all I used twenty odd years ago, but there weren't many quality epoxies around, other than the speciality aircraft ones like the 3M Scotchweld 2216BA (I think) that we used for bonding racecars together (and I still have a couple of tubes in the freezer, but It'd be cactus now)
