I think I will need to make my own shaft adapter in order to attach a timing gear to the spline of the power hd giant servo hd-1235mg motor that I just bought.
Essentially I want to mimic the center portion of the horn that is sold for that motor by Pololu (item #2374). The information I have on the spline is limited: I know from the hd-1235 spec sheet that it has 17teeth and a diameter of 8.80 mm.
Is there anyway I can have access to a more detailed drawing of the horn (item 2374) than the drawing provided? Is there CAD geometry available?
Are there any clever or off-the-shelf ways of attaching a shaft to this servo spline that I am not aware of?
