The stool is practically already made (and here is a photo of its progress). Only the seat base, sanding, gluing, and painting are left. That will probably be three videos. To make it, I used two different sizes of wood strips, 30×40 millimeters and 40×40 millimeters. To cut the 30×40 strips, I used the circular saw jig we had, but to cut the 40×40 strips, I couldn’t use it because the size of my saw blade limits the cutting capability of that jig to a maximum of 30 millimeters.
So in the video for this post, I will make a 90-degree cutting guide for the circular saw. We can always resort to a handsaw or a jigsaw, but if we have a circular saw with a decent cutting blade (saws usually don’t come with a blade for precise cuts, so it’s advisable to buy one, although it can cost more than 50% of the saw’s price), it’s best to try to use it.

This new cutting guide is very simple to make and very useful for cutting with the circular saw. We only need a 4 or 5 millimeter thick sheet of marquetry and a small wood strip or plywood about 10×15 millimeters. I use a marquetry sheet for the base because if I used a 10 millimeter plywood sheet, my saw wouldn’t be able to cut the 40 millimeter strip. Even so, I managed to cut the strip very precisely (a couple of millimeters more and I wouldn’t be able to cut it). The most recommended thing in this case would be to adjust the saw’s cutting depth to cut a bit more than half the thickness of the strip, rotate the strip 180º, and cut the other half (and sand any misalignment we might have). In my case, I didn’t want to complicate things and with a bit of care, I achieved clean and fairly precise cuts.


As this circular saw guide is so simple, I’m not providing plans, and I hope the video instructions are enough.
