hubby has a cordless 18volt black and decker circular saw and he says you can't cut round edges without cutting the excess off first. we made a oval table top. it was rectangular, but he cut it off in sections to make the curve, then used his reciproction saw to make the final curve cut. did he do this right, or i say , he could have just used the saw and gone straight around the curve. am i wrong or is he right?

A circular saw cuts straight lines best. That's because the blade sits in the kerf - the space where the blade cut out material - and the edges on either side of the blade rub against the blade. It's sort of like sticking a ruler between the pages of a book, right up against the inside of the spine. It's blocked on both sides, and can't move much.
You *can* cut a slight curve with it, but it's harder on the blade. A reciprocating saw would work better, but might not leave a nice square edge, depending on the kind he used.
There are circular saw blades made to cut curved lines. The blade is sort of triangular shaped, as if you sliced off part of the outside edge of the blade on 3 sides. There are still teeth left on the remaining outside edges.
You can also set the depth of cut to just barely cut through the material, but it still is hard on the blade, and you end up with a lot of sawdust.

You're both right...sort of. You can cut curves with a circular saw, but not very tight ones. The problem is that the diameter of the blade limits the radius of the cut. You can't cut a sharp corner with a 8" circular saw blade but with a 1/2" reciprocating saw, you can.

Trying to cut curves with a circular saw puts undue strain on the motor and places the user in danger from the blade hanging up and kicking back.

You cannot cut curves with a circular saw, however you should be able to cut curves using a reciprocating saw, assuming that it uses a thin enough blade.

Mam, your husband knows what he's doing.
Let him buy more tools to do the job properly.
He was right. Multiple cuts was the only way.
On a thin sheet, it is possible to go SLIGHTLY curvy.
Anyhting thick will be cut kinda straight.

no, you can't cut curves with a circular saw

technically you are correct but the method that your husband used is good practice. What he was doing, was to remove excess material so he could get a clean cut.

Yup sounds like he did it right if thats the 2 saws he had. I would have used just one saw (especially around corners)That would have been a jig saw.
