The only joints that performed poorly were those involving white metal.
(It is horrible stuff and just a poor modeling material in general.)

I love white metal stuff. It's great for many uses, esp detail parts with
thin cross sections. It's easily drilled, easily filed, easily cut, has
good strength and flexibility/plasticity, is invulnerable to chemicals,
easily painted even by brush -- what's not to like? Oh and it's heavy too,
which is wonderful for some uses (like GS gondola doors). The most
beautiful AB brake parts that I have are white metal castings. I wish I
could get more!
