update #3-second week manufacturing

This week we focused on manufacturing all the linkage components, including shafts and arms. when all the components were done, we press-fitted the busings we bought and tried to assemble components. However, we met a problem that the shaft does not fit into the bushing and also it is too short for placing two washers at the ends. Then we modified the dimensions of our shafts a little bit by reducing the length between the groove and the end faces, and made the shafts again. At the same time, John helped us to reamer the size of the holes and Claire looked for thinner washers. finally, all the pieces came together and worked pretty well. we can rotate each link nicely and smoothly.

This week we also machined the pillow stockes for our top car. Claire used the linear band saw to cut the pieces into right sizes and then drilled the holes on them by using the drill press. Next, Claire used 0.375 in reamer to open up the holes and press fit the bushings into it.

next week, we will still be working on our MCM- linkage, we are planning to assemble the right body plate with the linkage, machine the scoopers, and connect the linkage with motor. hope we can get that done by thanksgiving.
