Paul, et al -

Here are a few shots of the rear motor mount before welding.  I am doing
the final fitting tomorrow to precisely position where the rod end will be.

Mark

Did he machine those inserts out of solid bar stock?
Looks heavy. The inserts inside are a bit too long but that will
only add weight and other wise not hurt.

What is the wall on those tubes? Looks thin.
It also looks like electric welded tubing which is a no no.
Electric welded tubing is mild steel with lousy fatigue
characteristics.

It needs to be 1.25 OD seamless 4130 .065 wall.

Make it like the drawing. Welders are like that some times.
My Numerical Control machine tool programming teacher at Ventura
College, Scott Rabe, used to tell jokes about welders.

That guy might be a bit too independent for you Mark :)
