Not hard to machine at all if it is just a cut out and not any pocketing.
Just take your stock and stick it to a spoil board with some carpet tape.
Then machine away. Pocketing that thin is a bxtch because you have to get
the piece perfectly level. I have milled parts out of .010" brass that were
about .100" x .400".

When you way high temp silver solder what heat range are you talking? If it
is in the 1100 - 1200 ° F range than you can always use jewelers silver
solder. Your local welding supply store is also a good bet.
