I posted a thread yesterday about my Kemtron GP 20 rebuild/repair.
i asked in that post about what solder and heat everyone recommended. Well today I have done some of my own research and it’s now clear as mud.
i am not a novice at soldering, I have done electrical, electronic metal repair etc but I have not worked much with brass.
Many people recommend stay brite solder and flux. I am assuming the liquid flux however I could also see the need for the paste.
heat source is where it gets murky for me. Several people said a small torch. Others say iron.
Stay brite says use an iron on brass because a torch can soften the brass by anealing it.
I am turning you you guys, the ones with hands on experience working on brass trains.
Help me obe wan, you’re my only hope
my next question is about method,
my plan is to clean all parts with denatured alcohol, and then tin both surfaces to be connected. My hope is to use the minimum amount of solder to get the best connection.
Is this the best method. Also what type of clamps and or heat sinks do you use?
this is the main solder station I use, it has hot air and several different tips, the heat for the iron and air are adjustable as well as the amount of air flow.
i also have several regular irons in different wattages and tip configuration.
i have small butane torches as well as regular propane, mapp gas and mapp oxy combo
