Side Scan Sonar Tow Cable Sheave
Deigned by: Dan Scoville
Machined by: Dan Scoville
Goal: Make a sheave to hold a 0.1875 inch diameter steel cable for towing the side scan sonar.
Next I wrote a program to make the side pieces for the sheave. I had to make these in two parts since my homemade CNC does not have enough travel to do the whole part at once. So I cut half the part then flipped it over and cut the other have.
Next I roughed out the axle shaft and then cut the threads on the end.
