Piece of cake to make! I just used 2mm ally sheet cut with a jigsaw to whatever shape you want. no weight at all in it to bugger up balance points etc. The clutch would be the hard bit if the focuser knob shaft is not stepped like mine, but theres other ways to make a clutch. Can you unscrew your focuser knobs with ease?.......You have a crayford don't you??
