A little trick that will save lots of time when you have more than one
sheet to cut

Guessing that is a 10" table saw he is using. So it has about a 4" depth of cut. 5 sheets of 3/4" plywood. A 7.25" circular saw has about a 2.5" depth of cut. 3 sheets of 3/4" plywood. So he is able to cut 2 more sheets with the upside down table saw than if he used a common circular saw. It is an improvement in productivity. But enough to warrant the extra effort? Looks like the stack of plywood he is cutting is about 3 feet tall. About 50 sheets. So it will be 10 passes with his upside down table saw compared to 17 passes with a circular saw. Worth it? Its easier to push a circular saw than an upside down table saw. So I bet the effort and time used for 10 upside down table saw passes will be more than the 17 circular saw passes. So in the end its a negative from a labor, production, perspective.

This chap needs to use his obvious and vastly superior mind to invent a new and better way to cut plywood.
But where is his circular saw? Maybe he left it home, maybe it's locked in somebody's truck,
maybe it's on the roof and all the ladders went home. Maybe he let the smoke out or cut
the cord.


True. But your argument might be comparable to some other examples I thought of. Fixing the soffit on your house. But you have no ladder to get up there. The smarter, simpler, more logical person might figure out where to get a ladder. Buy it, rent it, borrow it. But the more creative might fix a hook to the end of a rope and throw it up to grab on the gutter. And climb up there to fix the soffit. Or he might recruit a friend who does not have a ladder to loan. Both climb up on the roof from the top of a pickup they park on the other side of the house and one guy hangs over the edge of the roof upside down and repairs the soffit. While the other guy holds onto his ankles. Or if he knows a painter maybe he could get hold of 50 paint cans and assemble a staircase of paint cans high enough to get him up to the soffit. All possibilities for the creative genius who can't get a ladder. Kind of like turning the table saw upside down instead of finding a circular saw.





Your math may be correct, but are you sure that you've accounted for all of the variables?

Oh yeah, one other question: Aren't you making a pretty bold assumption about the number
of cuts he plans on making? Maybe he's had his fun and he's done.

True again. But doing this upside down table saw once is maybe comparable to playing Russian roulette. Some people, maybe, get a thrill out of playing it once. Just once since even the dimmest know the odds are stacked against them if they play it too often. But I'm confident almost everyone will say even playing Russian roulette once is not smart. Like doing the upside down table saw cutting once is not smart.
