RE: [PSUBS-MAILIST] Shrinkage of plexi windows.

Frank,

             I just glanced at my copy of Stachiw's book but I think the deal is that there is a annealing shedule that happens before and after machining.  In otherwords the shrinking would take place before the machining and then another annealing takes place to normalize the effects of the machining process.

Does anyone have any ideas about a shrinkage rate for plexi windows when they are annealed ?

I'll be starting that gig here soon, and need a little more info. Frank D.
