I drew the parts in Rhino, exported them to SW, drafted, filleted
and shelled them. Exported them back to Rhino, added the flange
and rendered it. Whew! It needs a few more internal ribs.

It would weigh about 10 pounds in aluminum with a .2 inch
wall and about 6 pounds in magnesium. Tracy's current set up is
about 8 pounds for the adapter plate, spacers and bolts.
The 4130 steel schertz beam 30 inches long
weighs about 5.3 pounds for a total current weight of around
13.3 pounds. A mag casting would be about half that and
an aluminum casting would give only a 3.3 pound saving.
However the mold for the casting is going to cost
a lot so the price of ten or 15 will be about $500
or $600.

How many people would be interested in a mag casting?

Paul,
Have you included in your castings "Machining costs' .
George ( down under)


Yes that is including machining. It is a guess however.
