I came up in the trades using the circular saw that the carpenters who hired me used: 7 1/4 inch sidewinders.
However, nothing brings so clearly to mind the phrase “time is money” as being the company owner–and since it was a company of one (plenty of room to grow), I was also the lead carpenter, lumber mover, accountant and head of janitorial. So the work habits I had working on somebody else’s dime quickly changed. If there was a second here or minute there I could save, I did. And the first place I started saving big chunks of time on framing projects was doing away with saw horses, at least for cutting framing.
