![]() ![]() ![]() Obviously I haven’t done a good job here. Ok the wire that’s meant to be the shield is making contact with one of the other wires. Extruded aluminium is pretty flat so variation along the piece will be minimal.Īnd the angle will also help keep the aluminium flat, but I need to tapper this so it doesn’t get caught on the incoming spindle. I’m going to use a piece of aluminium angle bar as the touch plate for now. Ok I need to decide what I’m going to use as the touch-plate now. I soldered a crocodile clip to one wire end, and crimped a ring terminal to the other. I use heat shrink to neaten the joins and check that there are no shorts using the voltmeter. So this doesn’t become a problem later, once the wires are tinned, I snip the ends down a little so I don’t have too much metal exposed. This might be because I’m using thin solder and keep the iron on the wire core for too long. ![]() I noticed when I solder this particular type of wire, the sleeving shrinks a little because of the heat. I’m just sticking with the format of shielding and luckily I’ve got a bit of wire that I can use to shield here. Ok I’m going to make the touch probe for the CNC machine using this 3 pin aviation panel mount.
