I wasn't happy with how my motor mounts were turning out so I scrapped them and started over.  I stopped by the salvage yard today and picked up a nearly perfect bit of diamond plate angle.

It is mostly done at this point, but it needs to have the final bends done while it is on the mountainboard truck axle, and I put it on upside down.  Oops..

This should be a lot stronger than the first try without adding a lot of weight.  The tabs near the axle will get wrapped around it and bolted through.

I finished most of the battery welding, but I have some bad ones I need to go over them all again.  I also had one cell which felt a bit warmer than it should have.  I am wondering if it failed.  I'll check each group for any significant voltage loss tomorrow. 

On an unrelated note, there was a stack of seven beefy oxygen concentrators sitting at salvage as well.  I grabbed the one with the lowest hours (15k) for $5.  Borosilicate glass work here I come.  :)
