A router ATC doesn't need to be a tool changer or even an active component. I've seen videos of ones where there's just a rack with slots for each tool and the router gantry and tool changer spindle do all the work. For tool lengths, that's what a tool table is for. You set a base tool length an

I wanted to get an ORAC lathe until I found a teardown and rebuild forum thread on one. They're a Compact 8 clone and the back third or so of the cross slide is cut off so they don't have much travel. On Friday, May 12, 2017, 7:38:27 AM MDT, andy pugh wrote:On 12 May 2017 at 13:16, Les Newell

Works similar to the turret for the Compact 5 CNC and PC lathes. They turn one way with a ratchet pawl then back up against it. On Friday, May 12, 2017, 6:23:10 AM MDT, Les Newell wrote:Hi Gregg, The ATC on my lathe is a turret I originally made for a Denford Orac (a small education CNC lathe

Hi Gregg, The ATC on my lathe is a turret I originally made for a Denford Orac (a small education CNC lathe). It has 6 tools on a disc with a 6 position ratchet. A motor rotates the disc forwards to select the tool then backs up onto the ratchet to hold the tool in place. There is a microswi
