Re: N-Det upgrade parts ready to ship.

Hi Peter and John,

I went to the shop and the material will be ready for July
11 (Monday). However, I made one change in the dimension,
namely the thickness of the PVC. John choose and wrote 0.5",
which translate into 12.7mm. PSI has 12 and 15mm thick
PVC. I don't want them to mill the 15mm to reach the 12.7mm.

I believe the choice of 0.5" is clear and the change to 12mm
is correct. If this would be wrong, let me know and I will
make then change it. However, it would delay the work
enormously.

best regards

Francoise
