: I separated the field coils to rewrap them.Now I have to resolder them.But, I'm concerned about burning up my new wrappings as I attempt to reconnect the links.I'm using a small pinpoint propane torch since I need a sizable heat source to get them hot enough to solder.I need some type of heat sink/shield to protect the the wrappings.There is not a lot of room work with.Has anyone out there done this?How?
: Many thanks for your input/experience.

hi neil---heres another 2 cts worth---jack is absolutely right about using a soldering iron as opposed to a torch of any kind-an open flame will destroy the insulation--a best quality large electric soldering iron, while not cheap, is a good investment. another important detail is the solder itself---for any electrical work one must use "rosin core" solder only---the "acid core" type used for radiators will destroy electricals. one must be careful buying solder--some sneaky dishonest suppliers will offer alleged 60- 40 which is 60% lead---be careful to get the real 60% tin--40% lead variety---give the joint a coat of glyptal--an insulating varnish--to seal it after it cools.
it will seem to take a long time for an electric iron to bring the joint up to a temp at which the solder will run freely and fully fill the joint---have patience and take care to flow the solder thoroly and all will be well.
hope this helps ---carla
