I'm going to use lacing tape instead of cable ties for the looms when I can, today I started tying the switch wires, it took many attempts to get the technique even close to being acceptable. I've settled on tying a clove hitch then a square knot to lock it, more practice is required. I'm looking forward to GAM being able to visit as he used to do this professionally when he was rebuilding B747 engines for QANTAS.
