face=sans-serif size=2>Makes sense especially to increase stifness, but I
ponder the weight savings after adding the resin and fiber especially is you
are laminating with the 5.7oz 3K plain weave (most standard stuff). It is real
easy to get over strong, and landing gear usually needs a load distribution
into the fuse more than super strong gear plates. On my firewall, built
out of lite ply by Lance, I used 2oz glass to "Strengthen" the ply..it is a
waffle design so very stiff. The idea being that the fiberglass will help keep
the lite ply from fractures-or waffle delams-disbond. Cannot get 2oz CF and
the 1K CF (4.2 oz) that we make or canopies and chin cowls out of would
be overkill.</FONT> <BR><FONT face=sans-serif size=2>Have you compared
weights? that would be interesting. I never have but alway worried about
it.</FONT> <BR><BR><FONT face=sans-serif size=2>How's that Guitar hero

ply will be strong or stiff enough and I don't want the weight penalty of
aircraft ply. I also have laminated regular aircraft ply to give extra
strength to things like landing gear plates. This allows me to use a thinner
aircraft ply (in my mind anyways). </FONT><BR><FONT size=3> </FONT>

face=sans-serif size=2><BR><BR>The proper bandsaw blade for composites does
not have any teeth on it at all. The blade consists of a coating of
tungsten carbide bits like rough sandpaper grit adhered to the leading edge of
the band. The blade cuts by abrasion and will break before it wears out. Any
blade with teeth is bad for composites as it will dull and the teeth can grab
and delaminate the sustrate or your bond to the
honeycomb.<BR><BR><BR><BR><BR>Gray Fowler<BR>Senior Principal Chemical
