But you are correct to think that five solid = well-glued plies of poplar should hold a screw as well as a solid piece = of poplar and better than five poorly glued and fitted plies of = who-knows-what wood - after all, a 11 plies of a multi-ply maple pinblock holds a = screw as well as a solid block of maple. I think it is just that most plywood is poor-quality wood that has gaps, etc. Most marine ply is better wood, = but one would have to inquire as to what specie the plies are. And I wouldn't = expect a piece of marine ply to hold a screw as well as a same-thickness hunk of = solid maple - but better than a piece of CDX plywood.</FONT></DIV> <DIV><FONT face=Arial></FONT> </DIV> <DIV><FONT face=Arial>Terry F</FONT></DIV> <DIV><FONT face=Arial><BR><FONT size=2></FONT></FONT></DIV><FONT = face=Arial size=2>> At 06:36 1/18/2005 -0500, you wrote:<BR>> >Be = careful about using plywood to secure a screw into - it typically does <BR>> = >not provide good holding power - you might want to consider a tee-nut on = <BR>> >the other side.<BR>> ><BR>> >Terry Farrell<BR>> = <BR>> <BR>> Marine grade would be more likely to hold a screw, wouldn't it?<BR></FONT></BODY></HTML>
