Has anyone had success (or failure) using fiberglass window screen material as a breather in a vacuum press?
From contributor C:
I have used fiberglass window screen material in my bag press for several years. The screen is duct taped (at the ends only) to a loading panel (1/2" plywood). The screen slightly overhangs the sides of the plywood. I use a piece of polyethylene plastic sheeting on top of the screen (also taped at the ends but not the sides). I lay up my work on top of the polyethylene, then slide the loaded panel into the bag like a tray. Inside the bag, the loading panel sits on top of a conventional bleeder panel (scored melamine). Because the screen overhangs the plywood, the vacuum easily feeds from the bleeder panel to the screen under the plastic. When the glue has cured, I slide the loader out of the bag and peel the veneered parts from the plastic. I have used the same piece of screen for a couple of years, and usually get dozens of loadings from each change of plastic. The screen works well on curved parts also.
