I also read the Silver Solder article and look forward to the continued.
During my younger years i did a reasonable amount of Silver Soldering but alas not much in the last 30 years. I had to relieve the fellow who was the company pro while he was on long service leave. he trained me up in just 2 weeks with one special lesson. That was to Silver solder a bolt to a bumper bar which was already chromed (these were for buses and coaches). This was needed on the cover plates if any dipstick snapped a bolt off during assembly. A delicate situation as the heat could destroy the chrome. During his 6 weeks sojourn I had to do it twice. This was always done using Oxy as the plate was from 3/16" to 1/4" thick.
About 4 years ago I had to re solder a bandsaw blade this time using Porpane/Butane took me 3 goes for a successful join.
