It is a very easy and quick project if you have access to a lathe. Total time for the project was about 6 hours not including design and the cost was about $30.
1.5” dia. x 12” long steel
1.25” to 1.5” dia. wood pole (recommend ash or white oak)
#10 x 0.75” long wood screws
Boiled Linseed oil
Drill press or milling machine
Step 1: Design
To go from a picture to an actual design I fist printed the picture full size. I knew that I wanted the final diameter to be approximately 1.5" and the bore to be 1/2". Once I had a print scaled to this size rough dimensions were measured directly off the print. These dimensions were then used to create the cad drawing. I tweaked the design until everything looked close to the original. Since the originals are likely to have been made one at a time I’m sure there was a good deal of dimensional variation so I didn’t worry too much over the actual dimensions. I just picked sizes that I felt were easy to work with.
