Matthew,

Let’s see if I can resolve some of your questions.

Question Set 1

1. Spacer size. As noted in my video, I placed 2 spacers of the same size, but will resolve the final design when I add the Toughbox and motors. This should be finished by Monday for my next blog entry.

2. Wheel assembly. Yes, I created a standard wheel assembly and placed it 6 times. Again, I will modify when I complete the drive system with the belts.

3. Broken constraints. I only got the one broken angle constraint as noted in my video. If this becomes an issue, then I would build the wheel assembly separately from the frame, place it in the main assembly, and then make it flexible.

4. Looks like you resolved this one.

5. Deleting the bearing. I opened the wheel assembly with two bearings, deleted one bearing and saved the assembly. Since the bearing is part of the KOP it is easy to add or remove bearings.

Question Set 2

1. All my models are based on the drawings or files provided by AndyMark. The STEP file assemblies from AndyMark will probably not have any constraints, so each part will be free to move anywhere. You can ground all parts to resolve this. If you need the assembly now, use the STEP file provided by AndyMark. My Inventor version is being built as part of my webinar series. As noted earlier, it should be ready by Monday.

2. I will check the clip ring size.

3. If I understand correctly, I would place an angle constraint between a face on the locknut and a face on the Toughbox to align as you want.

4. Mating the hex faces. Yes and no!! Your work flow is correct and does involve repeating the same steps, so when that happens I always look for a quicker solution if I know I will be doing the same work flow over and over again. For future reference, look at iMates. This adds one half of the constraint to one part and the other half the other part. When you insert a part in an assembly, it automatically assembles itself. Very cool, but not used often enough. If time permits I can add an example to one of my webinars.
