Dave, I have started using methacrylates as they seem really suited to our hobby, the specs indicate that composites and such like are the most suitable materials to adhere to, that very little surface preparation is required so ideal for those places we cannot always get to to scuff up really well etc.

Attached are the specs for Devcon 531, Hysol 942 and Hysol 9464, Devcon 531 (530 very fast cure version) if sourced well are generally cheaper than Hysol 9462 and others.

I believe Stumax fans are assembled using this stuff.

As you say a really 'strange' smell, which seems not to cause irritation but just smells weird. One really important thing with methacrylates is they must not be moved during cure, this breaks the bond process and joints will be weak.
