Check out the square motor couplers I built.
They are 5MM straight X .187" square.
I built 4 square brooches to cut the square hole. Each one fits in the hole produced by the last one.
They were ground out of high speed steel on a surface grinder then sharpened with a diamond file.
These fit my Castle 1520 and 1518 motors. I have a pair of each for my Sprint Cat 40 build.
Could'nt find anyone that sold these, so I made my own.
I can build 5MM, 6MM, and 8MM versions of these if anyone needs one.
