Re: Converting a Photo to a Line Drawing?
Chris, in the past I've tried several methods of copying/photographing wafer switch connections, but its a helluva lot of fannying about with marginal sucess.
Best bet is to simply use pencil/pen, paper, & some circular stencils, and a decent A4 or A3 clipboard or drawingboard.
My simple efforts can be seen in Post28 of "Roberts Valve Tester" dated 18th Oct.2020, picture 3 of 5. Some switches were re-used big old "Yaxley" paxolin wafers, and others were smaller NOS wafers out of a MAKA switch building kit.
By drawing the wafer's circuitry, particularly old chassis wiring, using pencil or pen, one can later colour-in the individual switch contact wiring with crayon. Because its jolly difficult to photograph the exact colours of old faded wiring insulation.
