PRODUCT OVERVIEW Maybe you want to get started building log furniture, or maybe you already have the beginner?s kit and want to take your furniture building to the next level. Either way, the Home Series Starter Kit is an excellent choice. This kit features a 1? and 2? tenon cutter, 1? and 2? forstner bits, and a 20 piece plan booklet (for all those projects you want to build).
