JB Weld, I've found it to be seriously strong stuff.

To "araldite" your joints preparation is all important.
Clean all joint surfaces with coarse wire wool or emery paper to provide a mechanical key, then swab them with acetone to remove all dust and grease. You must get the 50:50 araldite ratio correct and you must ensure the two compounds are thoroughly mixed. Mix on a non-greasy surface using something like a lollipop stick (from art supply shops). When all acetone has completely evaporated you can apply the araldite. Once assembled, gently warm the completed joints with a hair drier which will make the araldite less viscous such that it fills any air pockets - note that such pockets may tend to "bubble out" as they expand in the heat

damm... Ive got over 100 joints to do. With that process it may take a while but better to do it correct
