That depends entirely on the size of the material you are going to work with. The tenon should be at least 1/2 to 2/3 the size of the log or branch you are building with. If you decide to get into working with log or branch projects get yourself some Forstner bits to match the tenons. They give you a nice flat bottomed hole to seat the tenon into.What are the most used sizes need in making tenons for log furniture
They sure are but when I can make a bed and get $800 for it, well it goes a long way toward a return on investment.
