Tools of the trade
A hollow chisel mortiser is a power tool used to “drill” square holes. It works by first drilling a round hole with a normal boring bit, followed by a square shaped chisel that squares up the sides of the hole. The round bit spins inside the square hollow chisel. As waste is produced it is carried out by the center bit. This tool is a great time saver if one builds a lot of tables or chairs. I bought this one with money from one of my early commissions seen below.
