Chassis, day 2

Got a good 5 hours in today, feeling every minute of it now. I completed more of the frame but ran into a minor issue with the front end I fabricated yesterday. Seems my math was just a bit off and it was 3/4 of an inch too tall. When I added in the side rails it just didn't line up. Two hours later it was fixed. I was worried about my welds but when I cut off the tubes I checked and yea, I think they're stronger than the rest of the metal. I did complete the rear bulkhead which began to close off the driver and passenger area.

Rear Bulkhead:

Cockpit side rail (aka arm rest) Anyone other than me impressed it's level?
