A lot of hammering and clean up of my cuts later, the drivetrain is coming together.  The motor alignment was just about spot on. I also made new bearing spacers today so I can actually tighten things up.  Yay!

Did I mention this is all being done with hand power tools and parts brought along, in an RV park, on a plastic table?  We are currently in Mineral Wells, TX and are rolling across the US headed for Seattle. This would be a fun toy here for Ryden, so time to get off my butt and finish it up.

The chains still need to be shortened.

My latest welds suck worse than ever and I will need to redo a lot of them, but the battery is in its final form.

I'm still having a hard time getting the weld current right.  I burn through or don't penetrate at all.  I tried adding a ballast resistor made from some AL wire so I could tune the current better, but the contact area needs tweaking now.  I still haven't checked if I killed that one cell yet either.  Of course it was one of the strong ones, so replacing it would throw my whole pack current balancing off as well.  Cross your fingers...

More is better for welds, right?  :P
