About 2 years ago I bought the complete set of 8mm WW collets from Sincere. The collet set cost me more than twice what I initially paid for the lathe. The lathe was $450.00 when I bought it many years ago. This price included the cross slide, lever collet holding tailstock and free shipping. Since I bought it, price increases have almost doubled the cost of the basic lathe package. When I brought this up on another forum years ago the usual nasty comments came out calling the machine "a piece of Chinese junk". These comments were made by people who never used the machine. With only a few exceptions (Boley F1, Star, Cowells) I also have every other model of watchmaker lathe in existence, so I had other machines to compare it to. In some respects, I took a chance when I bought it, but it turned out to be an extremely accurate, dependable lathe. Personally, I am very happy with the machine.
I gradually added the other accessories over subsequent years and pretty much have everything Sincere offers for the lathe. Their quiet running induction motor was around $200.00 but I like it much better than the brush type universal motors that are normally used. The induction motor turns the same RPM whether running free or under a load during a cut. This helps keep a consistant chip load and reduces pivot breakage during the turning operation.
