I was fixing to order some 5/8 cast acrylic from delvies plastics inc. I'm looking at making duck call toneboards with it. Does anyone here order their acrylic from delvies and does the 5/8 stock usually measure a little over .625? I called but was only told it has a tolerance. I didn't ask but I'm sure its only +/- a few thousandths. I hate to put in a big order and it be too small for a toneboard. If it will go straight out of the box into the collet chuck would be great.
