I need some galvanized fascia gutters made. There are four sections and each has an inside corner, two endcaps, and a single outlet. Used to have a sub that would come to the job and fab stuff like this very reasonably, but I no longer have access to that sub, however, I do have access to the material. I never watched how they soldered this stuff when it was being done and now wish I did. What tools and materials are needed, and briefly, what’s the process?

solder, flux sandpaper or steel wool, 500 W iron or propane torch, some skill or willinginess to do a few tryouts, all used for what they look like they should be used for. Oh yeah, something to hold everything in place also.
Lots less skill need for 500 W iron vs. propane torch (most people get stuff too hot with a torch) . If you can solder a radiator, the gutter is a cinch.
To solder galvanized trough, I use a large 24 oz copper soldering iron and a propane torch to heat it or a small iron that is heated continuously by a "B" tank(the 500W iron will work well) for flux, muratic acid applied with a acid swab.To hold the trough sections together ,vise grips with the flat pad ends and50/50bar solder.Solder as much as possible on the ground then do the minimum in the air.MOST IMPORTANT when disposing of acid ADD THE ACID TO WATER NOT WATER TO ACID.and wear eye protection when soldering.I never need to wire wool to clean.Heat the iron, wipe on sal-amoniac block,tin it ,Flux trough,tin trough,clamp together,flux a little and apply heat with iron. Now you are a tin man!
Thank you gentlemen, I will pick up a large soldering iron and give it a try--there's plenty of spare material here to play with.
Do as Jako said, but take time to pre-tin before assembling the pieces. Also, do it outside. Muriatic fumes are nasty. I usually run a fan blowing lightly across where I'm working, Good luck.
