Some of you might remember me from years ago. I have not been in the forums for the past few years. But I have been improving my machining skills. I decided to give machining a yoyo another try. I currently have access to a Haas Mini Mill 2 and that is what I am using. Next year I should have access to a cnc lathe, but until them I thought I would see what I can do.
Step 1: Start with a cylinder of aluminum 2.25 inch in diameter
Step 2: Machine the top nice and flat
Step 3: Spot drill the axle hole
Step 4: Drill the axle hole
Step 5: Rough out the shape quickly
Step 6: Refine the shape with a square end mill
Step 7: Finish the shape with a ball end mill
Step 8: Glass bead blast
This was just a test part so I didnt machine the bearing seat or the response. I am waiting on a smaller tool to arrive to make those easily. I also didn’t thread the hole yet. I really wanted to see how the surface would turn out. I have a few changes to try but for a first attempt it turned out pretty good.
