So my tip for this nice little iron is pretty worn down. It had some fancy coating that wore off long ago, so I've been sanding away the oxidation and occasionally refiling the tip to give it a good point. Over time, I'm left with this stub. Still usable, but I'm gonna need a replacement. I didn't have any brass or even copper rod around, but I did have some old rusty steel rod that was the perfect diameter. I cut it down, stuck it in my drill press, and on high speed I began removing material with a rasp and files in order to create the narrow part. That little screw on cap needs to grab the tip for good thermal contact, so I made sure to shape that edge real good. Gave it a nice pencil tip with some patient file work, also in the drill press. I removed the rest of the rust then tinned it with a MAPP torch and something which was probably 50/50 solder. It came out pretty good. Just thought I'd share, because I'm bored. Also, any implications of using steel I should be aware of? It'll be less efficient I imagine, but I tested it and it still works well enough. Could the increased load of the steel shorten the life of the element, since it's not a very good conductor of heat? I'm not too worried, it didn't cost much. And although I haven't looked much, I haven't seen any tips that fit it. All the more reason to roll my own.
