Didn't get as much done this weekend as I hoped due to other commitments and various interruptions. I did get the two engine bay top rails tack welded together which I'm very happy with. This required the manufacture of a jig to hold the strut tube in the right place and angle while everything was tacked up. Here's the two finished articles.
And here's an end view that shows the 5.3 degree installed angle of the strut tubes.
Tomorrow's job is to tack these into the main chassis along with the rear uprights (already cut) at which point I'll have the outline of an engine bay :)
