Power Cube v16.8

Development

Published the latest design in Sketchup below

This design has had few updates lately. Here are the latest updates:

Aug 2016: Twin 18HP engine design in the works - mostly complete, will be built in the September Power Cube workshop

Snapshot: Hydraulic ports - 2 3/4" male outputs from the top of the pumps, 2 3/4" female returns and 1 1/4" low pressure return.

Shapshot: Suction plumbing: Use 2 suction strainers and separate hoses to pumps, as reservoir ports are only 1 1/4" and these suction strainers are only rated at 8GPM each.

Question

How should corners be formed and welded for optimal strength? Here is one image of a corner, with one of the horizontal members in the corner and the others welded to it:

Should the orientation be the same for all 8 corners?

Should we employ any special grinding / welding procedures for the one weld where all three members meet?
