So, life got in the way. Spent about a year helping my son build and tweak his 1986 Camaro and we have him setup pretty good now and it's time to get back to my project. Here is the front end of the frame welded up and the wholes we were drilling.
Ok, frame almost finished welding it, ran out of gas on my welder and I can't get down to get it filled for a couple of weeks. I included a close up of the front. The short story is I measured 1 1/8 inches from the front of the tubing frame rails on both sides. Then placed the pipe on the frame rails and made a half circle on the outside and inside. Keep in mind, I made the inside frame rail where I could weld a full 360 degrees and the outside is only 180 degrees. I'll post a final round of pictures once I get the gas and finish the welding. I can hardly wait.
Ok, several set backs. Didn't have oxygen/acetylene so had to use grinder and hack saw to get things cut but we at least got everything cut. Also had to buy a new welder, mine finally gave up. Found what appears to be a pretty good welder though and it's American made. Wow, who new! It was a little more expensive but it sure puts down a pretty weld.
