Heres a pic of it without the coil fitted, need to make up a friction pade so the big roll is under tension and the front part will have to make up a PTFE nozzle as the copper contact tip it heating up and grabbing and shaving the wire at any faster than 400rpm. Also thinking of making a pressure flap that sits on the small coil so the wire is held on the coil as it gets wound as it may help stop it wanting to jump as it reaches the end.
