As one old silversmith to another, can you for Janet's sake actually specify the SIZE ie dia of your sievert torch, to me thats essential tech info for someone like Janet who is basically a bench jeweller, and probably never worked in a big shop like you have? and I do.
I use torches by Calor, and they range in size from 1/2in up to 2in dia for heating.
For silver brazing I use the BOC standard oxy acet torch using oxy and propane.
for heavy heating I use an oxy/acet cutting torch ie size up to 1in thick steel type.
The propane torches are mounted vertically on a 1in dia pipe which is an old bicycle repair stand modified.
This has an 1in angle square platform some 9in square.
On that I put stainless steel weldmesh 1in sqs. I use that for heating up anything prior to forging or shaping with the 1.5in dia propane torch head underneath. When in a production run of say 2500 hot drop stamped bronze plaques this stand is modified to form a oxygen free enclosure .with a lift up lid to place and remove metal prior to placing in the die.
all rather time critical. Only a few seconds to do it right.
As mentioned before, im lucky to have 3 of the B'ham Hazelwood and Dent drop hammers( do you know these? James?) here apart from the coining presses and fly presses.
Happy forging to everyone this Uletide.
