Converting a handheld circular saw to a table saw is not difficult and is something that can be done within minutes. However, as with other processes involving the saw, you need to exercise caution while handling it to prevent injuries. To mount a circular saw on a table: Prepare a sturdy table with a hole at the center for you to place the saw. Create a removable panel on which you can mount the saw. Create a flat edge at the hole, using a slightly thick piece of wood and some glue. This flat edge serves as a platform for the fence, which is a piece of wood that acts as a cutting guide. Cut an appropriately sized hole in the panel, and using screws, fasten the saw to the board in a way that the majority of your hardware lies below the tabletop. Once the above is done, adjust the fence until it aligns with the saw blade. BOOM! Congratulations, you have successfully converted your circular saw into a table saw.
