With the motor mount plates installed you can see that the welder back in '48 must have got plenty of sleep the night before. Both the motor mounts and trans mounts measure plumb and true. With the headtube angle set, and wheel and drive line points dialed in, its time to pull the stock frame out of the fixture and bend some tubes.
We'll use a heavy wall 1.5" DOM for the lower loop, it will be doing twice the job of the 2 stock legs. Also the front motor mount will only be supported by this tube so its important to adjust for the added abuse. We'll have more flicks of Keith's Witch Finder later this week.
Best regards from Richmond,
