Scrappy Lil’ Circular Saw

Like a lot of us, [Andrea] has a habit  of disassembling everything he runs into. He recently came across a fairly substantial motor he’d salvaged and envisioned its new life as a small circular saw.

[Andrea] bought new cutting discs, but the rest is salvage and scrap. He had already mounted the motor, pivot, belt, and gear to a wood block, so he added two more wood scraps for a base and a cutting surface. He screwed a metal L beam to one side of the surface block to keep the disc adjacent to the edge. A couple of washers keep the disc rotating freely. [Andrea] used a piece of hydraulic pipe and a cylindrical nut to attach the disc to the pivot. This assembly can be easily tightened by hand, so changing discs is a quick operation.

He kept the electrical as-is and mounted the box to the saw body. This 30W motor runs at ~600-1000RPM which isn’t fast enough to cut wood. Undeterred, [Andrea] plans to use it to cut steel bolts, copper circuit boards, and metal plates. If you need to cut through anything and everything, try this 700W DIY table saw.

Circular Saw to Table Saw Conversion

Corded circular saws are a dime-a-dozen at any old thrift store, yet table saws are a bit more of a costly investment — have you ever wondered if you could just make one out of a circular saw? [Matthias Wandel] did, and he just so happens to be very good at woodworking! He makes a lot of great woodworking videos to share on YouTube, and in his latest blog post, he shows us a rather elaborate way to convert a plain old circular saw, into a functional table saw.

While the concept seems simple, unless you do a lot of woodworking, you’ll probably marvel at how easily making things comes to [Matthias] — we know we did. By the end of the video he has a fully functional table saw that can raise and lower in height, and cut at different angles.

If you’re interested in making one yourself, he does a very thorough job explaining the process in his video — check it out after the break!
