Also in a live axle system you will need hubs on/in the wheels rather then the bearings (i think) you have currently.
Also you may want to add another corner gusset on top.
Excellent first CAD, i look forward to seeing great things in the future!

After looking more closely I see the problem in my CAD
I have never dealt with hubs separate from the pulley because our team has always chained our drivetrains with the sprocket directly attached to the wheel
The pulley is attached to the axle with a set screw so they will spin together
How would I go about connecting this wheel to the axle so they spin together?
I looked at Andymark's website and found these hubs

Most of them used keyed axles and we do not have the resources to machine a keyed axle, can you buy those?
