Hey Brian!
We need more progress pix! It has been what, 3 months since the last round? This is Bryan from last week. I was picking up my permits for the shop
Check out the garage progress so far (link in my signature).
Let's keep in touch. I want to see what else you have done to date. No doubt you are getting good at welding? If no one has mentioned this, on the thin stuff you might try a sheet of brass as a backer to help prevent blow outs. Steel doesn't like to stick to the brass so you can congregate your puddle and keep it in place for a sec'. I have yet to try it after reading it somewhere but I have been wanting to see how well it works after personally dealing with 'Tin Foil Blowout' syndrome on other cars I have welded on.
