WW Pressure Pot question

[Justturnin]

Ok, I have my second attempt at Worthless Wood going in the form of 3 different blanks. I have them under 50psi of pressure. My question how long do I leave them under pressure? They are PR. I know I should leave them in the molds for about 24 hours but do they have to stay under pressure during that time as well to prevent the PR from shinking off the Wood?

Any input would be appreciated.

I would leave them under pressure for that long, but that won't keep the PR from shrinking.
