Sherline(TM) ER Collet Spindle Headstock
We started as a small manufacturing facility for performance engine parts and continue in that line of business today.  In the beginning, we searched high and low to find super precision tool setups for small lathes and mills. We settled on a Sherline CNC system and discovered it’s limitations on precision immediately.  Everything seem to be off by up to several thousandths, even after taking considerable time to dial everything in.  The Sherline product line up is great for the hobbyist, but it is just not suited for some industrial applications...until now. Necessity is the Mother of Invention After much trial and error, we developed our own adaptations to make our Sherline lathe a super precision machine.  Developing a collet system that could handle long stock was the key for us.  Amazingly, we were soon putting out parts with precision down to +/-.00005” out of round...and that was even beyond the specifications of the headstock itself!  With this success, we decided...”Hey, if we love our setups so much, maybe others are looking for the same!”.  So, there it is in nut shell....
