Where can I find the wax string that is used to tie up the wires inside the Kits and is there any special tricks used to make it look neat? I used to tie up wires in aircraft a long time ago but I don't recall what knots were used and how to string up the wire. Any help would be appreciated.
Thanks

I never thought of that.
Good to hear from another ex-aircraft technician in the forum.
I still use waxed string left over from my old airline days.
I use double knot every inch or so.

Yes, I had gone to training for avionics and worked in that field for about a year. One of my jobs was to label wire and tie it up in wire runs to be put into aircraft. I remember using waxed cord but don't recall the knots or exactly what type of cord it was.

Last I remember, there is a diagram of how to tie the wire together in the back of the ARRL manual (ham radio). Might check there. FWIW, I think plastic tie wraps are better, especially since making changes means just snipping the ties and putting back new ones later. Also, in my experience, neat wire bundles can have a negative impact on the performance of the unit (hum, cross talk, etc).

I do exactly that with my projects - except that it is not waxed cord, it is rayon-cored PVC covered lacing cord.I have a page on my website with the stuff I use on it as well as a step-by-step guide to the knots used. It also links to the site where I buy mine from.
There are plenty of examples on my site too via the various kit building menu links. In fact, the Kit1 PQ Signature is probably quite similar to some of the looms that you will have to plan.
Hope this helps.

Thanks, great looking sight. I wonder if you can get this cord at a sewing shop?

The type that I use is exactly the same as I used to use all those years ago at Ferranti Engineering. It is specifically for that job and it is very cheap.It consists of a central core of very fine cotton-like strands (rayon in fact). These are covered by a PVC outer layer. The idea is that the core takes the strain and gives it strength while the out layer is both collapsable and provides the friction necessary to make it non-slip while lacing.

Where are you buying the cord now? I have searched on the internet and came up with a couple of places but don't know what cord would be the best.

I mentioned it on the page that I referenced earlier.I get mine from the RS Components website (see link below). This is in the UK and is one of the longest established professional component suppliers here.
The part number to search on is 554-080
