We've had a lot of discussion about the new PowerCube and the new LifeTrac designs and I think I have wrapped my mind around the new frame design. Here is a screenshot:

It's been some time since my last update. The latest activity concerns the new Power Cube design - using a Volkswagen engine. I expect to meet with Jay early this next week to complete the rebuild of the engine and secure the engine. I still have a few more parts to get - especially for mounting the shaft coupling and engine mounts. I have been working on the component layout for the new Power Cube - it will be quite different from before, as the engine/pump mounting is horizontal rather than vertical. Also, the plumbing and engine are larger and heavier and I will be adding a pressure relief valve. The sizing of the hydraulic pump has been a big issue and is documented here:
