Plan a Wood Working Jig as a Support for Your Wood While You are Sawing.
To make even simple wood projects you can not have your wood flopping over, snapping off, or binding and kicking bac,k as you cut.
You don't need a fancy woodworking shop, or even a workbench to safely support your wood pieces.
In order to cut your pieces with a circular saw, you need to raise the wood off the floor.
The 'Without a Doubt" Simplest Support Jig.
The very simplest way to do that is to take two 8 foot long 2x4s, cut them in half, so you have four 4 foot lengths. Lay them out on the ground as shown in the photo.
Next, lay your wood to be cut across all 4 sections of the 2x4s, with 2 of them to the right and 2 of them to the left of the line you need to cut.
Arrange the 2x4s under your work piece, so that, as you cut, neither side will fall. Each side will have 2 pieces of 2x4s under it. This helps to prevent your saw blade from binding and kicking back.
This arrangement of 2x4s will support lengths of wood boards, as well as 4x8 sheets of plywood.
However, when you are cutting 4x8 sheets it is difficult to guide the circular saw all the way across the 4 foot wide sheet. If your supporting 2x4s are lined up just right, you might be able to kneel on your sheet as you push the saw to the other side. But if you kneel in the wrong spot, you might damage your sheet.
A Better Support Jig for 4x8 Sheets.
A better circular saw cutting jig is to buy a 4x8 sheet of foam insulation. Lay that on the floor, and then lay the best side of your 4x8 sheet on the insulation. Each cut of your circular saw will make a groove in the insulation. But your 4x8 sheet will be well supported throughout each cut, allowing you to kneel on the sheet without concern for damaging it.
By now, you will already have made the circular saw cutting jig for cutting plywood, so that your cuts will be absolutely accurate. To use that jig you will need to cut notches in the side of your 4x8 foam insulation so that you can clamp the cutting jig to your sheet that is being cut.
A Wood Working Support Jig for Your Workbench.
If you do have a workbench, you will still have pieces that are too long, or too wide, or both, to be able to cut them safely on the edge of the workbench.
Just plan a wood working jig like this one. This jig was made to be the same height as the workbench, so that the boards that hung over the edge of the workbench would be supported. With the use of the Kreg pocket jig, this wood working jig was a simple wood project. It is very handy, as it can easily be moved closer or farther away from the workbench, as needed.
