One curve you can cut on a tablesaw
How can you make a tenon on a dowel or spindle if you don't own a lathe? You can use your tablesaw, as shown in the drawing. I first set up my rip fence to define the length of the tenon. Then, starting with the blade down and running, I hold the dowel into the crotch formed between the scrap board and the tablesaw top, and raise the blade slowly to create the shoulder depth of the tenon. Finally, I rotate the dowel to complete the shoulder cut and then nibble away to the end of the tenon by passing the dowel back and forth across the blade.
