This is the lamp recently posted on the Photo Gallery and the detail shots. The lamp is all wood except for the wire and light sockets and the parts as shown are threaded such that the lamp can be assembled without glue. The sphere is attached to the base with a 5/8"-10 male thread. The shades have a 1/2"-8 female thread that accepts the male thread on the hollow coupler then the other ends of the couplers are inserted in the 1/2" holes in the sphere and secured with wooden nuts. The lamp cord is fed up the base into the sphere, the the lamp socket with pig tail wire are fed from the shade to the sphere. The shade caps are screwed onto the shades and the sockets are secured with knurled metal nuts. The 2 pigtail leads are spliced to the lamp cord, then the wires are pushed into the sphere and the finial top is screwed on. Last screw in the 4.5 watt LED bulbs in, plug it in and turn the switches on.
Yes I do have an obsession with wood threads but I did try to come up with an overall pleasing design. I welcome all comments good or bad.
