<br><font size=2 face="sans-serif">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 size=2 face="sans-serif">Have you compared weights? that would
be interesting. I never have but alway worried about it.</font>

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>

This doesn't sound like something one would find at the local hardware
store. Where can these blades be found?</font><font size=3> <br>
</font><font size=2 face="Arial"><br>
BTW, what if you have aircraft ply laminated with carbon fiber? I would
think in this case one would need a blade with teeth.</font><font size=3>

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>

What is the best blade to use on a band saw? It has 2 speeds, what is the
best speed (1,450 / 3,000 rpm)?<br>
<br>
I need to cut down two 12 x 24 panels and would like a clean edge ( 1/8”
CF/Nomex/CF panel, and a FG/Nomex/FG panel) .<br>
<br>
Nope, don't use the band saw much….<br>
<br>
Thanks,</font><font size=3> <br>
