      The saying "go big or go home" comes to mind. Guess I will stay home.

        The pallets are perfect on the k&t.. probably because the spindle center line can only get to within 1" of the table.

          Finally got the little mill back on the big mill.. took a bit if finesse to level/square the base/Y axis. (without warping the casting..) We have a .0005"/10" level that works very well for these situations.

          Currently the column is <.001 square over its distance. (both directions..)

            Not the fastest swap in the west... again - designed in the 60's

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

                    Redoing oil lines.. It didn't have metering valves and the Y axis ball screw was never plumbed..

                      I hate plumbing.. Getting there with a few side trips. Had to mount the X axis ball nut. It was so out of square that I machined 2 new holes instead of trying to use the existing 4 holes. (also made it easier to mount with the oil plumbing.)



                      Checked clearance with the table...



                      Another view.

                          Ran some oil through the saddle. Checking the flow. These are bijur flow regulators I got off eBay. I think they will work great. I slid the y axis on and it slides very easy on the film of oil.

                          (These are not made for 4mm tubing - but I found out the pressed in reducer removes easy. I just need to be careful that the tube doesn't protrude too far into the regulator - they don't flow then.. )

                            Things like this - the x axis stepper mount was getting in the way of the oil fittings.



                            So - snip snip here and there...



                            Getting things lined up pretty good. The really sucky thing is the table is slightly narrower than the saddle. (you can see the the ways and oil troughs) No one knows the story behind that goof. I plan on grafting an aluminum piece that bolts to the table to extend it over the ways. (mainly I want the oil to mostly stay under the table.)

                              Without going past the ways - it looks like travel will be 10" x 7-3/8" X 10-5/8" (XYZ)

                                1/2 done. Went suprisingly smooth...
