Does it sew? Testing out the motorized leather patcher

I had several requests to see the leather patcher in action, so here's a quick video showing it sewing through a few different thickness of leather.  I also cover the needles I'm using, since they are a bit non-standard.

The leather I tested on was probably ~4oz oil-tanned pullup leather.  The second test was 4 layers totaling about 8mm of thickness.  The leather is moderately supple.  I should have grabbed a few pieces of thick tooling leather but didn't think about it at the time, sorry :(

Test thread is #69 polyester, needle is 134-35 / DP-35 LR chisel point in size 120/19.  This replaces the 15x1 / Hax1 needles that come with the machine (although it does require some modification)
