I have wanted to try chasing threads for some time and found a used set of thread chasing tools on line over the past winter. I’m not sure which brand they are – the tool is one piece of steel with a “female: end and a “male” end, that reverses in the handle. While using the tool a plastic screw that threads directly into the handle tightens against the steel.
A couple weeks ago I was able to try them out. I made a little elm jar and glued pieces of PVC pipe into place on the lid and into the neck of the jar. With beginners luck, I was able to achieve usable threads and almost perfect grain alignment between the lid and the jar.
