[TowerTalk] Metal Thermal Rate of Expansion

[Mark - N5OT]

I hate to be a big ignoramus, but why, if this is not an issue for 
Gedas' 10 GHz mount, is sweating joints that seem to be similar to his 
design a common practice in machinery design?  Can someone help me 
understand what I am obviously missing?

If it was me I'd stick it in the oven and see what happens.  If that 
didn't seize it up, then I'd put it in the freezer and repeat the 
experiment.
