For that outer plate, if you really want to do it, I would use some C channel or box tubing instead. Just going to 1/4" plate would be rather inefficient. Using C channel how 488 did on this base is a much stronger option than just using plate. Once again I would prefer box tubing for the extra rigidity, but that's just me.
As for the gearing, you'll find that the cost of AndyMark gears is very nice (same for their quality).
The 14T pinion for the CIM motors
The 40T gear
The 14T gear with a hex bore
The 50T gear
You can probably even find a way to use AndyMarks various shafts (from their gearboxes) to eliminate even more custom parts from the design. |
Yeah, thats how I design my gearboxes. I usually find an easy way to use AM gears. They come prebroached and the service is great! They even did a custom gear for me.
You could probably pull off that 10-1 reduction gearbox with 2 globe motors by putting
these hub things on the shafts of the globes, using
these gears on those hubs, driving a
50 tooth gear with that, having a
14 tooth gear on the same shaft as that 50 tooth gear, and then having a
50 tooth output gear.
That would be a 10.5:1 reduction. You could swap that output gear for a 48 to get a 10.1:1 reduction.
