will a Mig welder work for this? I know as much about welding as I do about quantum physics. what settings should I use?
I think you mean "steel"Tig is for aluminum. Mig for steal
+1I think you should do a little homework.
I have welded aluminum. Steel. Copper with a TIG.
Most small aircraft frames are TIG welded chrome moly steel frames..............
thanks for the info...sounds like a have lots of work to do in a short amount of time... this stuff would be much easier if I had moneyJust to add more in the same direction, I bought a MIG and only worked on exhaust pipes for the first 30 hours and some scrap metal on my work bench. I then moved to frame work on (more art then function) speaker stands. I have started a Go-Kart frame from scratch and repaired a few trailer frames. I am still not ready to weld my Raptor frame and had a shop repair some small areas before I had it powder coated. Just my two cents. Someday I will pull this off.
I have used a siphon bead blaster form a 5 gallon bucket outside to work on trailer frames and its ok for small areas to weld. Not sure about the gravity feed type. I know that the pressurized version that has an air tank with the media in it is much faster. I have a 30CFM air system and my siphon is just good enough. Even my scat blast cabinet media blaster is to slow at times so I would think if you have a small air compressor and your looking to strip your entire quad frame you might want to use chmical stripper first and do some clean up on rust with a little sand blaster.
The 01s had an aluminum subframe, 02 660s and up used a tubular steel subframe.........The subfames are usually aluminum. It can't hurt and won't take long to pull the cdi. If you have a good work connection (sometimes mis-called a ground) and placement you shouldn't have to worry about it. However it is your project so assume as much risk as you want.
Personally I would conpletely remove the subframe and repair it on the bench if its that bad.
