Hi guys,
Next set of videos in this series:
In this video I start laying out and machining the slot in the center of the dovetail, that will recieve the rack gear blank, the rack gear blank will be fastened to the dovetail with two 2-56 screws, so holes had to be drilled in the dovetail slot as well, wich required a little more accuracy in measurements and table movements to get the holes in proper locations. That's where I started using edge finding methods, and dial indicator readings, to obtain those locations.
In this video I start laying out and machining the rack gear blank, to fit the slot in the drill press, then more features are machined into it, to fit the slot in the dovetail block, then holes are accurately located then drilled and tapped, to dryfit the rack gear blank to the dovetail block with screws, to make it one assembled unit.
Next up will be to fabricate a cutter on my lathe and mill, to be used to cut rack gear teeth, then proceed to cut those on the rack gear blank.
