Hi Jeff - sorry to be the bearer of bad news but Moly is classified as a
"refractory" metal which are essentially impossible to get an acceptable
solder joint. The best information I have in my library is in the AWS
Soldering Handbook (ISBN 0-87171-618-6) Section 3.3.11. You need a
intermediate solderable coating such as nickel or copper on the Moly and to
get that layer adhered you need to clean the Moly surface with some pretty
nasty etching materials (HF, NaOH) and processes (molten baths, boiling
baths). Not something to causally try.
