I need to accurately rip some 2x12 boards into multiple 2x3.5 boards. They are about 5 foot long. Because this is home center lumber (douglas fir) I also need to knock the rounded corners off.
Like the title says, I don't have a table saw and I don't know anyone who does. I do have a circular saw with a small detachable rip fence that came with it. I also have some saw horses. I can buy some sacrificial MDF to use a temporary work surface if I need to.
Any tips would be greatly appreciated. Accuracy is important, but so is safety so I want some advice from people more experienced with this sort of thing.
