Homemade table saw from circular sawI have seen a number of "homemade table saw" projects on YouTube, which mostly consist of bolting a handheld circular saw to the bottom of a piece of plywood. That works well enough, but making depth adjustments is difficult, and tilting the saw usually impossible.
So I set out to see how good a "table saw" I could built from a circular saw.
I started by removing the shoe, adjustment mechanisms, and blade guard from a Makita circular saw. The Makita is a nice saw to use for this because it's fairly good quality and is less loud than other saws.
This was the sort of project that's mostly experiment. So I started by making some cardboard cutouts to go around the saw, just to visualize what shape of plywood I needed. I then drew the shape of these pieces on plywood...
The mount on the other side of the saw is kind of small. I cut a piece of wood to fit around it, and screwed it in. This part has to be screwed in only, because it needs to come out again to get the saw out.
I was able to cut this piece out of a piece of 2x4 on the bandsaw.
I really don't like working with a router. Dust flying everywhere. My fixed base routers, like this one are quite good at dust collection with the fixed base, but all my fixed routers are already mounted in jigs.
I used some door hinges, but drilled a few extra holes in them. The standard hole positions for door hinges are too far from the hinge pin. I added a countersink to the holes using the tip of a larger drill bit.
I used the same approach when I built my tilting router lift.
After that, I put a zip tie around the trigger switch to keep the switch permanently on.
Now, with the plywood flipped over, attaching a piece of wood to act as a temporary fence, using one of my long reach clamps
There's lots left to do on this saw build, and I'll cover that in my next article.
