This little project was more about experimenting with a Greenlee combination drill tap than edge marking stock. Add, too much nice walnut scrap and the need to fritter.
The Greenlee drill tap bit is convenient. It drills and threads in one combined operation. The leading segment of the bit drills a slightly less that 1/4” hole. The second segment follows and threads the hole to 1/4” and 20 threads per inch. This accommodates 1/4” rod which can be all over the shop for jigs. To avoid stripping the threads, a cordless drill in a portable drill stand was used to slowly cut threads.
Experimentation yielded an excellent way to turn custom knobs with a threaded rod insert. I threaded a piece of scrap. Cut it to an 1 1/2” cube. Screwed in the threaded rod with a touch of Gorilla glue. The rod, cube attached, was then inserted in a Barracuda key chuck on the lathe.
Dimensions: Body, 1 1/2” square x 4 1/2”. Three eights (3/8”) dowels on a 1 3/4’ center.
