In this video I will make a simple table saw with a circular saw.
First I screw a small 1x1 strip below my board.
I drill pilot holes, because I don´t want to break the strip when I insert the screws.
That strip will be my guide to cut a groove in the board.
I measure the distance from the saw blade to the end of the riving knife.
I will use a distance of 4cm, just to have some margin.
I put the circular saw against the strip, and I mark the position on the board.
I make another mark 4cm in font of that.
I take the saw blade casing apart.
I remove the riving knife.
And I assemble the casing of the blade.
I check the position of the saw.
In my case, the saw is too near to the edge of the board.
So I move the marks 4cm to separate it.
I clamp the board to the table frame.
Using a square I make sure that the saw blade is at a 90 degrees angle with the board.
I rest my saw against the strip, and I move the base to the first mark.
I don´t push too much the saw against the strip, because that could deform the metallic sheet that connects the base with the rest of the saw.
And If that happens I won´t have a vertical cut.
I turn on the saw, and I push it down, cutting the board.
Now, I move it straight on, cutting along 4cm, until I can see the second mark.
And there is the groove I need.
I assemble the riving knife.
I check that both, the riving knife and the saw blade, fit inside the groove.
I will use some bolts with blocking nuts to attach the circular saw base to the board.
I drill four holes with the same diameter of the bolts in the saw base.
Two holes in the front of the base, and two holes in the back.
I clean all four drills with a file.
I put a couple of boards below the board.
Right in the groove. And I clamp everything together.
I put my circular saw in the place, where I want to attach it to the board.
And I use the saw base as a template to mark where I need to drill the board.
Now, I drill the holes.
I insert the bolts in the holes.
And I pass the bolts through the holes I drilled in the saw base.
I put the blocking nuts.
Using a screwdriver and pliers I tighten the nuts.
Now, I turn the board and I remove one of the bolts.
I drill a counterbore, to set the bolt head flush with the surface of the board.
I must be careful, because I don´t want to drill too deep. It could be easier with a router, because they have an easy to set depth stop.
With a small screwdriver I can flatten the bottom of the hole. The base of the bolts head is usually flat.
I tighten again the bolt and the nut, and I repeat the full process with all the bolts.
I fold in some centimetres of painters tape on itself.
And I left 3cm that I still can paste.
I press the switch, and I put the painters tape around it.
Being fold in half I will not have glue on the switch when I remove it.
Another option is to use a plastic bridle to lock the switch.
I screw my board to the table frame, but first I drill pilot holes.
The screws I use have a bevel below the head.
I think I can make a countersink using a Phillips screwdriver to set the heads flush with the board.
If needed I can use a file to make the heads flush with the board.
I put a wooden bar against the saw blade.
I draw that line. I will use it to set my fence.
So far my fence will be that wooden bar clamped to the table.
Now I have another fence. You can watch how I made it in my channel.
I check the distance from the blade to the fence. I measure from the beginning and from the end of the blade.
I will need a safety switch to turn on the saw.
Now, I can cut with my table saw. But I will need some pushers to work safe.
I think it was not a good idea to use that particle board in this wet climate.
Now I have another homemade table saw that I made with a plywood board.
