MS8

Hole in One got together again this week to finish MS8. Today we used the lathe for the first time! We made the hole of the pinion bigger for it to fit the bushing and the axel. We also manufactured the axel, for which we used the band saw first (to cut the rod) and then the lathe (to make the grooves) We also attached the rack to the arm using epoxy.

Everything was going great for Hole in One! We had finished our work in the machine shop and were ready to assemble our most critical module. The assembly was almost done and, after being in the shop four hours, we were ready to go home; all we needed to do was to put the sliding arm in the guides, but we hit a speed bump! For our surprise, clearance between the rack and the pinion was not enough and the arm was stuck out of the guides. In other words, we had a big problem. But Hole in One did not panic. We analyzed possible solutions and we arrived to the conclusion that making the slot of the guide bigger was the fastest way out. So we went back to the machine shop and used the mill to make that slot a bit bigger. Did you know that the thickness of three sheets of paper can make a huge difference? That is by how much we made the slot bigger and IT WORKED!

Now our most critical module is ready, and Hole in One keeps scoring!!

Here is a video of the module assembled and manually working (we have not installed the motor yet)



Happy Thanksgiving!!
