It never gets dull, but here at work we break them on occasion...probably
set up wrong. You are set for your entire pattern life...as a matter of
fact people could send stuff to you to cut and you could charge them 50
cents an inch or so......after 10 years you will break even, just like
everyone else who offers pattern services.<br>

I did get a Tungsten Carbide band saw blade. Mc Master Carr doesn’t seem
to carry it. I bought mine at Industrial Carbide Saw out of Louisville,

say is smooth easy cutting…Very impressive. Thanks for the tip.</font><font size=3 face="Times New Roman">

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><font size=3 face="Times New Roman">

I often laminate lite ply in situations where I don't think the lite 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). <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>

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>
