I learnt to do lacing using nylon waxed cord, in the end used to love doing it. used to make the cableforms for avionic equipment that went in to the cockpit. it was broken down in to lots of stages, and after every stage it had 100% inspection. 1. cut, strip and tin wires. 2. put on ident sleeves. 3. solder wires to any sockets. 4. put heatshrink on socket connection and shrink. 5. lay wires on to wiring pin board for that harness. 6. finally get to lace the harness. i was about 17 at the time and it took quite a few weeks to get to the point of not getting a laced harness rejected by inspection. 🙂
So glad you decided to lace the harness. I have redone harnesses in Collins and Drake gear and as you mentioned the process moves along quickly. I really enjoy your channel and look forward to more of your video's. If you didn't find the article regarding a simple circuit to exercise a sticky meter, let me know and I'll dig through some of my old mags and see if I can find it. Though the circuit is very simple and easy to throw together. As I recall, you simply switched a positive LOW V then a neg. V and use a pot(s) to prevent too much travel in both directions. I jury rigged something years ago and fixed several meters. Exercising the meter back and fort for 30 mins to an hour did clear whatever was causing the problems. It was either contamination or oxidized wiring. 73, Glenn WA4AOS
I haven't been able to find metal films in higher resistances (>1k) that are spec'd as non-inductive. All the data sheets I have read except one make no mention of inductance, which makes me reluctant to trust them. And the one I did find were for resistors no larger than a few hundred ohms.
Very Nice job with old wiring and really helpful and enjoyed it . thanks Mike

Great Job! Great series!

I've been thinking about making a new harness for my HW-100.
Great video! Where did you find the lace?
Thanks, I got it at an arts and crafts store, can't remember which one. It's just waxed nylon cord.
Why carbon comp resistors? They drift in value more than metal film. Metal film also are lower inductance. Great videos.
