You can do it. I did it with the MAPP torch with the hose on it, (pictured above in another post). I was a rookie too. I put in a set of water bottle bosses and removed the cable "looms" from the top of the top tube and mounted cable stops under (on the side) of the top tube on an old Guerciotti. After a little practice on some junk frames it went fine. The hardest part was getting the vice grips in position to hold those cable stops in place while I heated them. They slightly deformed as I mounted them. So keep the vice grip pressure light. I tried the bronze, silver and also experimented with some steel rods on some of my junk pieces. I would not try the steel rods on anything of high value with MAPP gas. But it's a fun experiment to try to get steel hot enough. It's good practice for managing the heat.
