Frame Drive

[Deke]

So after reviewing a few different drive-trains that were posted on here I was curious about packaging a gearbox into frame. The attached was the result, and it has been dubbed the 'Frame Drive'.

Some advantages:
-Low center of gravity
-The ability to machine the components on a hand mill and lathe.
-Gearbox and frame integrated
-Single speed (no shifting complexity)
-Low maintenance (mainly greasing gears)

Questions and comments are welcome!

Hopefully this can provide some inspiration as other postings have inspired as well.
