Assembling the FRC Andy Mark base

[matthewgkerr]

I have been following Phil's assembly tutorials and have hit some sticking points. I have raised these questions to Phil but I thought I would ask for some feedback from the wider community.

1. I noticed that when you placed the wheel on the frame, you used two of the same sized spaces. The instructions for building the frame actually uses two different sized spaces. I only noticed because I inserted the spacer by attaching to the bearing, instead of the frame. Was this intentional?

2. The frame instructions gets you to build wheels with different hub configurations; one on the outside, another on the inside and the middle wheel with two hubs. You placed the single wheel assembly in all six positions. Was this intentional?

3. Following your instructions, I created the wheel axle assembly and copied it to another location. I found that some additional constraints break (other than those you mention... I think). When I attempt to spin the wheel on its axis (once i enable flexible), the wheel and one of the spacers move and are no longer attached to the axle. I'm wondering if instead of mating the wheel axis to the axis of the hole in the frame, should i instead mate it to the axis of the bolt, as well as mating the axis of the bolt to the axis of the hole?

4. I have created all the wheel configurations (manually because I got stuck on the previous problem) and got to the point of constraining a face of a hub (the wheel with two hubs) to the frame, but I got a dialog with three errors saying "constraint cannot find component reference". Now I'm really stuck. How should I proceed?

5. I also wasn't sure what to do about removing the bearings from the wheel assembly. Did you create new copies of this assembly, or did you remove the bearings from the original assembly? I think you must have because when I created new wheel assemblies (see previous) I edited the original wheel assembly, deleting the bearings when necessary. When I go back to previously created assemblies, their bearings are gone. Because all my wheel assemblies are using the same base wheel assembly. Should I be creating copies of the KOP wheel assembly? i.e. a wheel assembly with no bearings?

Thanks.
