I don't know how many sheets you have to cut, but it may be worth your
while to build a simple stand to cut the sheets standing on edge. It's
a lot better than climbing on top of the wood you're cutting.

You could mount this on a short stand and lean it against a wall, or
build several 2x4 triangles for support. That way you are working
standing up. Easier to make good cuts.

It's worth using a straight edge to run your saw against. If you're
doing a bunch of cuts, you can make a simple square with the corner of a
sheet of ply. A 30-60-90 triangle, 4 foot on the 90, can be a handy
thing to have.

i was thinking of placing them on SUV tyres which should provide
enough clearance for the circular saw. would the weight be sufficient
of will i have to clamp it somehow.

i guess ill get some saw horses for the smaller section. but it seems
to me tyres will be more stable and its not as far off the ground, so
the cutoffs are supported as they come off.


thanks
