Dec-1 Machining the Axle box openings on the frames. You're looking at both frames, dowl-pinned together and bolted to the table from the back of the Bridgeport facing Bill. The ends of the frames, with the screw holes, are actually the bottom of the frames. Inside each one of the four openings (the cutter is inside one of them) will eventually house the axles for the wheels. The center of each wheel or axle must be exactly the same distance from each other or when we connect all of them together with the side rods, they will stick, bind and would not roll! Since the existing dimensions and cuts on the frames were wrong, it made the centerlines unequal, along with making the openings of unequal width. What a mess. We had to mill additional material off the frames to make the centers correct, which left the openings oversize from the print--the first three openings ended up 2.510 instead of 2.327, and the fourth one was 2.570. That's nearly 1/8" and 3/16" difference--huge even if this were woodworking. We'll have to custom-size the axle boxes to keep everything right.
