The Anthony Tools Tenon Tool Adapter is well-made product that enhances your ability to turn accurate and repeatable spindle tenons on the lathe. The manufacturer advertises .002” tolerances for final fit.
It is designed to be attached to a 1/2” square nose scraper. The tool rides on the tool rest and also rubs against the bottom side of the tenon. The scraper cuts at the top of the tenon and produces a clean, smooth cut. The scraper quits cutting when the edge reaches the tangent of the spindle. This cutting method is meant to remove only the final 1/16” of material. Prep work for the cut includes 1) removing wood to within 1/16” of the final desired tenon diameter and 2) setting the tool to acheive the desired final diameter/fit.
I turn a small scrap of wood in a chuck to acheive the correct diameter. This allows easy removal of the test piece to fit into a pre-drilled hole. Move the tenon tool back on the scraper to turn a smaller tenon. This trial and error fitting process is slow at first, but I imagine a person would get quicker with experience. I plan to keep one tool set for 1” and another set for 3/8” for my typical chair builds. A quality scraper should hold an edge for quite a while since not much wood is removed on each cut. One wouldn’t have to go through the fitting process very often if you had multiple tools.
The manufacturer recommends applying wax to the tool surface to prevent the protective coating from rubbing off. I found that the coating rubs off of the tool too easily even with a coating of wax. Wax and glue aren’t a good mix, so I will likely hone the coating off of the rubbing surface and deal with any potential rust later.
If you want to produce precisely fitted tenons, this is a tool worth considering. Set-up can be slow, but the final product is worth the effort. The cut is smooth, precise, and repeatable.
