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.

Another variable for the mix:
It is likely that the table saw has more torque than the circular saw and can actually make the deep cut relatively quickly. The circular saw may require a much slower feed rate to accomplish the cut. " wrote in message ...

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.

It's likely max thought cuts are 4 and 3 and sheets, respectively, but that presumes as Leon notes, one has a circular saw with sufficient power to actually do a full three-sheet cut. If that's the case, it's a 25% decrease in number of passes which again presuming the case of 50 sheet pile (and the whole pile needs cutting) would be about 13 versus 17 passes. Hardly seems worth the effort, but he's a strapping fella' so handling the saw doesn't seem that much of a problem; one can move the cut sheets out from under it between passes so don't have to set it back down on the ground every time. Compared to trying to reach the middle of the top of the stack with a handsaw for those first few cuts, doesn't seem too bad a deal to me -- it's big and heavy enough kickback is a pretty minimal risk and while I don't think I'd have ever thunk of trying it (but I'm surely not stout enough to get the saw up there in the first place now and not sure ever was) but I don't see it as particularly dangerous. Unusual, yes. -- |

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. It's likely max thought cuts are 4 and 3 and sheets, respectively, but that presumes as Leon notes, one has a circular saw with sufficient power to actually do a full three-sheet cut. If that's the case, it's a 25% decrease in number of passes which again presuming the case of 50 sheet pile (and the whole pile needs cutting) would be about 13 versus 17 passes. Hardly seems worth the effort, but he's a strapping fella' so handling the saw doesn't seem that much of a problem; one can move the cut sheets out from under it between passes so don't have to set it back down on the ground every time. Compared to trying to reach the middle of the top of the stack with a handsaw for those first few cuts, doesn't seem too bad a deal to me -- it's big and heavy enough kickback is a pretty minimal risk and while I don't think I'd have ever thunk of trying it (but I'm surely not stout enough to get the saw up there in the first place now and not sure ever was) but I don't see it as particularly dangerous. I certainly would want it to run off the end and fall on me, still running. Unusual, yes. I don't see it as being much different than any other clickbait. |
