Old School Soldering

(1/13) > >>

joeqsmith:
I was given a few old torches that were removed from buildings before they were demolished.   These were used for soldering and I plan to give it a try.   A few irons were found with the torches along with some bar solder.   The one is a bit odd and I have not been able to find who made it.  The more typical one looks almost home made.

To attempt to solder electronics, I think I will need to make a custom iron.   The last iron I made was pretty crude.

One of the torches is 100 years old, based on the test date marked on the tank.   These use leather for the seals which can leak so I changed the design to use Viton seals (should be a little safer).

Testing the oldest torch.

SilverSolder:

What would it have been used for, 100 years ago?  Fixing Model T radiators?

joeqsmith:
Early cars did use lead in the body work but I suspect the torch predates that.  I would guess plumbing and electrical would have been the two primary uses for solder.   

joeqsmith:
A decent website with some general information on them.

One of the torches I was given was made by the Turner Brass Works.  There is a site which has some interesting historical information on the company.
