He's an true 0 scaler, impervious to the ailments of common man!
I find it easy to unroll increments of solder with my teeth as I work along the ROW. Think of it as a form of flossing
My method is more like an assembly line. I will drill all the holes for an entire project, clean off all the rail webs, insert all the preped drops, solder all the connections, then drop a touch of rusty rail paint on all soldered rail webs. It just goes more smoothly for me that way.
