Spent the last couple days in the shop making wooden screws and nuts. Screws are walnut, cherry, and osage orange. The nuts are sugar maple. I use a 60 deg V bit in a die grinder to thread the screws in a machine lathe - feeding by hand. The internal threads are cut with the die grinder using a 60 deg. V slotting bit - I only have one and can't remember where I found it. Both bits are carbide. I turned the screw blanks to 2", 1.5" for threaded area and coated with thin super glue to stabilize the outer edge of the threads while cutting. I cut the hexes for the nuts and bored to 1 1/4", then cut threads until the screw fit snugly. Then round the screw heads and nut corners and apply wax. I then clamp in a jig to align and cut the slot on a router table. 20191220_142833_resized.jpg 20191220_143055_resized.jpg
