Thank you Dave, I think the higher voltage iron is probably a good idea. Yes, I was trying to solder a pushrod wire to a clevis and also some soldering to a wheel. I just checked and my iron is a 30 watt. I see in the catalog that I can get a 60 watt. Sure wish I had bought that the first time. Yes, I also cleaned the metal and used flux, but I think you are right about that using a hotter iron. Thank you again for you help.
