I was just watching some of this and noticed the repair attempt on the Zamack,, solder of course will never stick and JB weld will fail also but you can TIG it with Aladdins 3 in 1 welding rod I have used it with a torch but with a TIG has better control of your heat. I have fixed in the past alot of zamack parts with this stuff it takes some practice but it is not impossible.. Ray
