Thanks for all your positive feedbacks.In the matter of the spindle,I'm not going to use anything large in first setup,one dc motor 200w3350rpm and a spindle I made myself.Spindle housing of steel with small head(one collet diameter;have few pieces of these,3,4,5,6,8 holes),I have some angular bearings(7201C),and I think it will be good for the first run.Later,I have in mind spindle with morse 3,ER20 collet chuck,which I also plan to do myself,and servo motor with VFD.
