Put the plywood blade (actually go for the cheapest one you can
find) in BACKWARDS (teeth point AWAY from the direction of the
rotation). It will friction cut. It gives a ugly burr that must
be knocked down with a file but the cut itself is very smooth.
Wear ear and eye protection, it is noisy and messy.

i put up some fencing on my back yard.. i use the same sheet metal that
they build the warehouses with... ribbed stuff, steel, i think they
called it aluminized or such.. one section has been up for 15 yrs and i
cant fine one scratch of rust on it.... well it came in 6 ft lengths and
is 28 inches wide.. i will be putting in the back section of sheet metal
now as the old cedar boards on the back fence have given out and i need
to make a gate and cut some of this sheet metal... can i use a plywood
blade to cut sheet metal and expect it to have a finished cut.... i dont
have a shear like the shops do and i know the hand shears will take
forever to cut this 6 feet length....

Use a blade made for cutting metal,only about $3.00

thanks for the info.. sounds good to me....

I agree about the metal cutting blade. My metal blade (for the circular saw)
is slotted...no real teeth. I also use it to cut plexiglas on a TS. A sabre
saw with hacksaw teeth blade will work too, as will a hacksaw blade on a
sawzall.
Good luck.
