I've been a little busy lately but here is the latest update:
I've modified the modules to the plate design with 4 wheels. It is properly dead spaced now (Thanks, that saved me a lot of headache). Unfortunately there is not a lot of room for spacers but hopefully the addition of a tire will add some rigidity. I could always add some plasma cut spacers if strength becomes a issue.
We also learned how to use our
bridgeport CNC with CAM software. Are last team "wave" didn't like using any computerized tools. Now we just have to buy endmills that aren't 0.02" off
(It might have been a non standard endmill but we rarely buy those)
If someone is interested I will post the CAD files here.
