    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.
