I do have a Taig which I use mainly for a clock that I am building. I am very satisfied with it, but then again I am not an expert and can’t realy compare with other brands. I am still learning to machine metal.
I do have the standard headstock and a ER-16 adapter, which is not the best solution for accuracy but it suits my needs for the moment. One can also have a headstock for 8mm WW collets, which I am looking at buying. Don’t know if the Taig would be suitable for watch work.
The clock I am building is based on a design from John Wilding: 16th Century Style Clock. It is taking me quite some time, but I am enjoying it. Here is a picture of what I have sofar.
I am currently working on the verge and crown wheel.
Thought I might share that…
