Thanks to VEXPro, WCP, and the iterative process
it is now dead easy to install a tension-able axle in rectangular tube. For practice, our students made a CAD model and the pictured prototype assembly during tonight’s work session.

Cool! It’s nice to see a simple picture of how the WCP tensioner system works.
I have a couple questions about your machining process:
- Do you have a digital readout (DRO) on your mill? It makes slots very easy to do.
- What made you put the dimensions on the drawing by hand rather than in CAD? I’m interested to see the benefits of this for new/ old members.
Noob question:
How does that bearing block hold itself in the slot? I understand the cam tensioning system, but with the VersaBlocks the block is affixed to the tube via bolts on the top and bottom. How is this?
There is a square boss on the side of the diamond-shaped plate that you can’t see in this picture. It fits squarely (!) into the rectangular slot.
The square boss has some nice radiused corners too.
Yes, our mill has a DRO. We were fortunate to have very nice sponsor donate that a couple of years ago.
A close look at the drawing will reveal that it is full dimensioned in CAD, and the paper copy is marked-up by the machining team to help with DRO references.
In a perfect world, machinists would never need to mark-up engineering drawings. In the FRC world and many others, iterating toward perfection requires a lot of on-the-fly tweaking.
