Before I attempt to bend and cut new tubing I'm going to try to tin the existing
pipes with solder, then reinstall them. Any thoughts, please chime in.
That's what I would try 1st Tom.
My advice is to only get it hot enough for your solder/tin to flow & adhere. more is NOT better in this instance. I would heat the affected area thoroughly and then move my heat to either side of the damaged area while rubbing my solder back & forth across the damaged area. Again more is NOT better, resist the temptation to go back over the damaged area if it looks like you got good cover & adhesion the 1st time. To much on the piping will result in the solder/tin plugging the pipe. Next I would consider replacing the Pipe with new 😉😊
Also make sure there is absolutely no water or oil on/in the affected area , and get down to bright metal (a Dremel with a wire wheel should work nicely) please wear safetyglass's Tom , you probably know this, but the wire wheels throw out wire bits with astonishing speed...especially the Chinese knock offs. 🤕
