Thank you and the others for setting me down a more sensible track.
aving only seen photos of chip trays I assumed that they were rather
thick. The explanation of the thinner material with rolled edge
is more sensible.

Thanks to all for the notes on construction of chip trays, ideas,
and where to look to find some items that may work well.
