Made some more progress over the weekend:
Finished making my balsa tips, and they are now attached. I still need to shape them. I pressed in some bushings, and sanded down the bearings. (Each one of mine began at .3140, and need to be approximately .3115). That is no quick task, even using a drill press. I plan to press in the rest tomorrow, and then get the bearings sanded to fit.
One of the three bushings went in very stubbornly, think I may sand the others down a bit before pressing them in. (They all measure .4400, with the holes reamed at .4375.).
What is a good difference so they still press in, just not so tightly? Any reason I shouldn’t do that?
