Will do Kim.

Very good Kim. Thank you for the pictures. Please let us know how you like the 1 mm wire. I have some that I plan to test soon.
It looks like the block of wood is resting on a piece of foam board. Is it Polyisocyanurate Rigid Foam Insulation Board?

Wow! €0.11/m is really inexpensive! That's equivalent to $0.12/m in the U.S. A 20 meter coil of 1 mm music wire costs twice as much per meter in the U.S. One meter long straight pieces cost the equivalent of €0.55/m ! That's 5 times what you pay for coiled wire Xavier! Xavier if I were to build a lo...

Very clever Kim. I see. Thank you very much.

I started building track 10 years ago. I seem to remember having trouble using coiled music wire with soft foam insulation board (XPS). I think other people also had trouble with coiled wire. But I am not certain. Kim, how did you straighten the wire or get into the shape you wanted? If you are glui...

Do not use coiled wire or stainless steel wire. Use standard music wire, also called piano wire. Pieces around 1 meter long work best, especially for curves (corners). Pieces 1 ft long should work fine on straight sections of track. For cars weighing 65 grams with the battery and with a 3mm x 4mm st...

Thanks for posting this info Kim. Looks promising.

Here are some photos taken in November 2020 and January of 2021. The weather is hard on my track.

Was the Maslow CNC method accurate enough to make a good track using 0.7mm dia wire? Or was the wire too high and too low in some spots?
What would you recommend to hold portable panels together when they are placed on a floor? Thanks for your help!

Kim,
How did your flex-chassis work out? How did you attach the printed circuit board(s) & servo to the chassis? Can you post a pic with PCB & servo?
