Marv,

 I used tin snips (shears?). These are the ones with a long handle (10 inches)

and 3 inch blades.  I then used a file to smooth the edges.  I also used a

tool (used to finish lightening holes) to put a 1/4 inch beveled edge around

the firewall.  This tool is about $12 from Aircraft Spruce and consists of two

closely spaced rollers on a handle allowing it to be run along the edge of the

material so the bevel can be formed.  The benefit is to stiffen the firewall

material to prevent near-edge oil-canning and provide a way to hide the fiber-

frax edge.

I cut mine with a pair of cheap tin snips  without trouble. I did have to

sharpen the tin snips

afterward. I also used the scraps for my nose gear shroud. I have an

AutoCAD (.DWG) drawing of the

shroud, but it is for the old style nose gear and might not work on the new

one. I have lots of

pictures of construction, oil cooler shroud, explosion proof foam in tanks,

generator bracket,

starter bracket (Honda Accord '77) If you think they might be of use I

could scan and zip them to

you.
