Thanks Pat, for taking the time and trouble to post that information!
I think in the end I will probably use the mig to tack the pieces together and have a "real welder" do the rest. That way I can fabricate the parts the way I want and have confidence in the welding also. I am going to have fun with my little welder.............and that's is the real fun, and also the purpose of "experimental aviation". Ron Smith, kr2ssxl, boat stage Cypress Ca.
