    I'd love that capability. It looks like a perfect fit.

    At the end of the project, there is a profound difference between spare parts and left over parts.

      How will you do this with it being so far outside of the ways and the carriage? Please keep us posted as some of us can learn from each others experiences.

        What I have done is turn the compound around, and use a boring bar to reach straight over. "Boring the outside" of the part. That does look pretty big, but it is probably do-able.

        You DO want a pretty low back-gear. Those speedy chinese imports are just not going to be able to do that stuff nicely. I would not want to work with that spinning at 150 RPM.

          Wait a minute. I see a stepper on that leadscrew. Is this machine CNC?

            Yes, check out the digital machinist forum here.

                Nice job. A trip to the dentist....

                Our microwiely lathe at work is a gap bed, but I don't think it's ever been out. I have the same job to do eventually on a set of 17" cast iron flywheels I have for the same purpose.

                  This will be around 27 inches or so finished.

                    Nice setup!

                    I've yet to run across anything that required me to remove my gap piece.

                      The gap is still in place.
                      Just a British pattern lathe.

                          Heck yeah!! Sawmill. You guys have lumber on the property or will this be just for sakes, sake? That is a BIG turn there, for me anyway.. Thanks for sharing. Love to see the rest of the project. JR

                              Well.... He wants to make one mostly for processing firewood.. Mostly. We have a vertical sawmill that we have used a ton for making actual lumber - but it is kinda hard to do big slabs or big logs.
