Use an 8d Nail as a Third Hand
If you’re without a table saw and need to rip boards with a circular saw, here’s a tip to make the job a lot easier. Drive an 8d nail through the board and into the sawhorse to prevent the board from slipping while you rip it. When you’re done ripping, just pull the board off the sawhorse, flip it over and pound the nail through and pull it out. It only takes a few seconds and eliminates the frustration of a slipping board.
Build a Custom Push Block
Here's a push block that works great and keeps your hand safely away from the blade. It's just a piece of 1/2-in. plywood with notches to fit 1/4-in., 1/2-in., 3/4-in. and 1-1/2-in. boards or plywood. The notches help hold the board tight to the saw table, and the top handle slides along the top of your fence.
Make the notched plywood 11/16 in. taller than the height of your fence. Then glue it to a 3/4-in.-thick board with a handle attached.
