what kind of hub did you use for the traction wheel?

Since your cylinder mount doesn't pivot, could you go into some detail about how you attach the cylinder to the module?

Had access to a CNC mill, decided to minimize the part count and not require ordering a pulley.

And now I know where Adam got his 2013 offseason drivetrain design.

What would someone look for if they were trying to find an extrusion like you guys used for the main structure of these rails? As well, how are you planning to connect the frame up once both side rails are completed? The pattern of those holes looks like it would be great for designing attachment points.

Online metals has it but a local supplier will give a better price.
