vaguely proposed a theory

If this is more than a one-off, I had an epiphany from this group. Use
sheest of styrene foam.

(1) set the saw to _nust_ cut the wood. This buggers the faom in the
end, but many guys get their stuff ree from building sites in the US.

(2) for those of us not up with that level of throwaway, I actually
built two 4*4 frames of 20*40 pine (20 deep 40 wide), backed with 6mm
ply and with 25mm foam inside, so that the faom stands proud. This
provides a firm level surface and lets me cut without bugge...ruining
the foam all the time. There is also a clamping oppo for saw guides
etc.

Tyres are not as predictable or stable. Do more. Clamp well.

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
