That's a great idea Stuart. For me, the hold down fixture wood be crucial 
and a good design welcome.
The mention of hold down fluxes left me with an uneasy feeling in that most 
fluxes are a bit active
and I would be concerned about the state of the flux after soldering. I 
have visions of an active flux
residue progressing as a corrosive agent over time unless it could be 
completely cleaned out after
soldering. A glue type holding agent might carbonize with the soldering 
heat. Has industry settled
on a flux that addresses these issues?
