Thanks for catching the spelling mistake. I'll fix that when I add the photos of the Spindle Motor mount plate and motor mount. I really regret not buying the larger X axis (and horizontal mill) version of the G3617. But at the time it looked like it would take up too much space and the extra cost couldn't be justified. Looking back now the $3616 Cdn. (all taxes in) price I paid for it wasn't very much. At least compared to what I'd have to pay now to replace it. https://www.grizzly.com/products/Grizzly-9-x-39-2-HP-Horizontal-Vertical-Mill-with-Power-Feed/G0757 It's about $6K US yet for some reason they convert that to almost $11K Cdn. My project #42 is to add an R8 Spindle into the column where there is one on the G0757 and an AC Servo to turn it. And cast up the other end to hold the horizontal spindle. There's no reason I couldn't add the horizontal mill feature since the table pivots the same way it does on the horizontal mill version. image of product G0757 Although, with CNC, is a pivoting table even needed for helical gear cutting?
