It’s slowly getting there. I have a lot of finishing to do, and I still don’t have the knurled knobs, but today I completed the first tuner with the correct threads and it is looking good.
If you compare these threads with the ones from the prototype post, you’ll notice that these are much finer. This means that more turns are required to tune the string, giving a better fine-tuning action. You will also note the radius on the base plate. The plan is to use identical base plates whether it is a trem unit or not, so I have made two to test both concepts.
