I share with you this, right now; I have NEVER paid anyone to fix anything except a broken clutch case at 16yo and a couple front alignments. I learn, ask or research how to do it.
I have a brand new Miller TIG and have probably 10 hours or so on the machine. The 1st material I attempted was aluminum (the hardest to weld). I STILL cannot get it perfect and everyone says, keep at it, keep practicing. But, I'd NEVER relocate a shock mount or anything critical just yet and YOUTUBE has gave me plenty of information.
Go ahead and try but you may want to pay for an experienced welder to do the aluminum welding for you. Al is "butter in a microwave"; I find it a very tough metal to master but I will get there.......
