I'm a little worried about the two plates that drop down and hold the bearings for the bevel gears. The .375" ID flanged round bearings are typically .220" thick or so IIRC, meaning the two fasteners are likely 6's or 8's. Those plates look like they might have trouble support the bearings hanging below them, but it's hard to know from just looking at a few screenshots.
The vertical shaft has only one bearing. This screen shot might be missing the other, but I'd highly recommend adding another one.

The bolts holding on the top plate at the moment are meant to be #10 bolts but may need to change those plates to give it a little more meat to hold onto the bolt. As for the vertical shaft and single bearing combo, that is something I have been working on but am struggling to find a way to mount a second one in a clean, strong and efficient manner.
Also the reason I am trying to stick with the chain rather than gears is because the chain is cheaper for us. I need be we can make the sprockets ourselves and the chain is rather abundant in our shop. Gears on the other hand by far are not easy to come by for us and are far more expensive for us to get.
