During this article will show how to build two different sets of lamps. Some pictures will be of each set of lamps. Both the Oneway 1018 and the Oneway 1224 lathes are used during these projects. A steady rest is a must to support the lamps while turning the inside and during sanding. The tailstock adapter and MDG cone support the lamp while turning the outside and sanding the outside. This process saves a lot of wood as segments are used instead of solid wood. The Open Segment Jig is a lot of fun to use. The projects are some what time consuming but the finished projects are well worth the effort. Very little wood is wasted therefore the cost for building projects like this are greatly reduced.

Please contact Charles Hale and or George Kattawar for the Open Segment Jig; the lamps are only a small sample what may be accomplished using the Open Segment Jig.

All credit goes to Charles and George for the development of the computer software and the manufacturing of such a fine product. Good luck and Happy turnings, Johnny W. Tolly johntolly@aol.com
