Even the backside grinding shown in the single frame of the video shows the effects of hand held sharpening. There is a curve on the flat side of the blade! Starting to look like a spoon. It’s impossible to get a flat surface when using bones and tendons. This effect was exploited to make the first lens when done in glass. Telescope mirror grinders do it too using two different hardness of glass, if machine done it would be flat. If those “slate” tiles are flat they must be ground flat not baked. No need to check.
After you have chosen the perfect table saw for your wood shop, the next major purchase one should consider would be a compound miter saw. While not as expensive as a quality table saw, a compound miter saw is invaluable for cutting compound angles (beveled, mitered and combination cuts) on the ends of a piece of stock. Once you develop your ability to make precise cuts with a compound miter saw, you'll find that your circular saw spends a little more time in the drawer than it used to.
Before I give you my list, I am assuming (and yes, I know what assuming does) that you already have a tape measure, screwdriver and a hammer. These are common household items that most people (woodworkers or not) keep around the house. If you don’t have one, they are a few bucks each and WELL worth the investment. AND they are my favorite types of stocking stuffers—even if it is just July, it’s already on my mind 🙂
I added an accessory mitre gauge to the saw for accurate cut-off work. The Incra Miter1000 showed up under the Christmas tree after the Lee Valley flyer photo with part number mysteriously ended up on the fridge door with a circle around it last December. A great addition, the Incra is light, accurate, and provides adjustable stops for cutting multiple parts to precise length. I will also make a plywood cut-off sled for the saw for squaring larger panels.
A layout square, or combination square, comes in 6” and 12” sizes. Most woodworkers use the 6” model, simply because it’s easiest to carry around. Also, most of the stock you’ll use will be no bigger than 6” wide, so 12” is overkill. The layout square is a triangle that you can use to mark square cuts on stock. Once you measure the length of the cut, you line up the layout square with the edge of the board. The short side will give you a straight, square cut across the end grain. You can also measure off angles with the layout square. This helps when you’re trying to measure for a bevel on a table saw, or marking a cut for a miter saw. You can even use your layout square to determine an existing angle. Just be sure to buy one made of metal. The plastic ones are not only fragile, but they also can warp, making them pretty useless.
