One of the machines that can be a breakthrough in our carpentry workshop is a table saw, especially when giving the wooden slats and boards the desired dimensions. The idea, as you have already seen in many places, is to screw our disc saw to a tabletop, cut a slot so that the blade protrudes from the other side and place the tabletop with the saw face down on the structure of a table. In order to turn on the saw we need to block the switch of the machine with a flange or another system like the one seen in the video.
The circular saw that we use to make our table saw should not be plugged directly into the electrical power anyway, we must put a safety switch that cuts off the power safely. I will use the one you see in the photo that I got of a workbench that I don't use much anymore. It is advisable to use something like this, since that type of switch is not easy to operate accidentally.
If you put a simple switch or a strip with a switch, you must put it so that you can turn the machine on and off safely.
Mi circular hand saw It doesn't have a lot of disk diameter, so I used a chipboard of only 1cm thick so as not to lose too much cutting capacity. As I did not trust that it was properly fastened by screwing the machine directly to the board, I preferred to drill holes through it and use screws with self-locking nuts.
I wondered whether to use a melamine chipboard (that's what I think those with colored "veneer" on both sides are called) or whether to use plywood. In the end I decided on chipboard because it stays flatter over time. This board has been in the workshop for a long time resting on one side and is still flat. I have a small plywood board in the same condition for half a year and it is warped.
It won't be my last table saw, but I guess I should make something like this in this woodworking blog. You will see that the board that I use is a little small for the structure of the table, and that it has a cut on one side. As this is provisional I did not want to use a new board and luckily I had this chipboard in my workshop.
As soon as I can I will put a board that covers the entire structure of the table and I will place the motor of the miter saw that I have disassembled, which has more power and will give me more cutting capacity.
