    Hi all. Im looking at cleaning up my setup alittle bit. For the lever/control arm that connects to my motor I made a steel one and its fugly. Looking around other builds I see these very nice aluminum connecting arms and cannot find anything online that I can buy. Does everyone own a cnc mill or am I missing something?

    Thanks

    I struggled with my motor's controls arms. So I decided to mock one up in fusion 360 and 3d print it. Went though some trial and error till I got it right. After I was happy with it, I sent the drawing snd stl file to a CNC shop to make. Cost me about $150 USD + shipping for both arms. Expensive but It fits like a glove.

    Good luck.

    Im going to try and mill my own but i don't have a full mill. If I fail, would you be willing to share your fusion file? I use solid works for my printers so I can make the changes needed for my output shaft but it would at least give a good starting point.

    Thanks

    I did a thing! I only have a drill press and some basic metal tools, BUT here are my new control arms.
    I bought a end mill bit and very carefully and SLOWLY, milled these out of solid bar aluminum.

    -P.S. - Thank you adgun. The hand reamer worked perfectly and the fit is extremely tight.

    Thanks Yinger
    I am happy to hear becauce i made a mistake the hole must be 16.7 not 16.9 mm before the reamer
    This is the old way to make presice holes.
