This probably isn't what you thought it would be. I need to
photograph a biker on his bike. To do this, I need to lay down a sheet
of 1/4" plexiglas that the bike will be placed on. The plexiglas is
there to provide a reflection of the bike on the floor. I need to place
under the plexiglas a subfloor (white paper on top of it, then the
clear plexiglas on top of the paper) so that the plexiglas can be
supported and not crack. The subfloor will be on the ground (supposed
to be flat ground, but what ground is truely flat?)
I first wanted to use some 1 1/8th 4x8 t&g subfloor panels, but these
don't seem to be available around here anymore. So, I thought I would
glue and screw together two sheets of some 3/4 type sheet (plywood or
osb) to make a 1.5 inch thick panel. I would make two of these 1.5"
thick panels and lay them side by side, maybe pin them or use biscuit
joints in table leaf fashion to create a subfloor.
My question is:
Do you think this will be stiff enough to keep the plexiglas from
deflecting and cracking? Keep in mind that it will lay on the ground.
