I need to buy some high quality sheet goods around the Philly suburb area. I will be bag pressing 1/2'' sheets to make a final thickness of around 1.5''. I'm using the press to try to get the ply as flat as possible. I will then be veneering both sides and edges. The ply must have holding power because I need to mortis in knife hinges to support the massive doors. Baltic birch sheets are not wide enough only coming in at 5'x5'. I need 80'' Any help finding a distributer or advise would be greatly appreciated Thanks.
