    UPDATE: Things are gonna slow down some from here on out, folks. Having a minor preparatory procedure tomorrow AM, and then a major surgery on Friday. Outpatient deal, that will last 4 or 5 hrs, will be spending the weekend elsewhere. I'll probably be reading the forum but won't be at my computer or my shop for a couple days.

      EDIT it'll probably be next week before I do much with this project again. It's not my first round of surgery, unfortunately. I'm hoping that things are almost done, there is a quarter million $$ in my skull now. Maybe in 4,000 yrs some archaeologist will find it and think we had some weird religion.

          Wow over 2,000 views! I wonder who's doing all the viewing? But so few comments...
          It's a me. Sorry. I've been following but not taken the time to examine closely enough to have a totally coherent idea of what is going on. But I must say I'm very impressed with your setups and determination to get everything done with a 9" SB!

          Good luck on you surgery, I hope it all goes smoothly.

                  I looked at his website and saw something that might have been adaptable to my lathe... So I sent Andy an email containing a drawing with the dimensions of the mating part on my lathe and asked if his casting could be adapted. He sent a snail-mail with a paper cross sectional drawing of the casting as received, with dimensions. Unfortunately I can't adapt his part to my lathe.

                  I was impressed that he went out of his way to send me a paper cross sectional drawing so I could make the decision myself. Customer service like that is more and more rare. So, I'll give him a shout out to say "thanks".

                    Post op selfie, I look and feel like crap, little aches and pains all over. I know they must have had one of those cheap universal radiator hoses shoved down my throat, the kind with all the ridges. Slowly getting steadier and stronger. About a 3hr op to remove an infected implant. They will have to replace it with a new one in a few months. Meanwhile there is a picc line (a permanent hose) up a vein in my arm going into my heart for the antibiotics. I've been saving the syringes to make precision oilers.

                      Hope recovery goes smooth & speedy to be ready for your new implant, you must have some farmer in you repurposing those syringes!

                          Wow it feels good to be back at it again! I have to be careful not to get my IV hose wrapped around the lead screw...

                          Continuing where we left off on the work table, the two cast-in lugs needed to be faced off, drilled, and tapped for 3/8-16 (say 10mm).
                          It was pretty easy to do the marking out, just for a sanity check.
                          The table is mounted on two legs when the machine is assembled, that's what this is all about.
                          First up I removed the top slide once again and bolted the table in its place.
                          Then used a MT blank in the tail stock to square things up to the spindle:

                          Spot drilled, drilled 3/16 and then 5/16 to tap 3/8-16.
                          This is why it's super handy to have a drill chuck on a Morse taper to fit your spindle ID.

                          In the same setup, use the drill chuck to get the tap started nice and square to the work:

                          And finish it out with the tap wrench.
                          I had to use the T-wrench because the bigger wrench wouldn't clear the ways.

                          In aligning the work for the other hole, I can simply thread a 3/8 bolt into the existing hole
                          and grab the other end of the bolt in the tail stock drill chuck.
                          This will give me "good enough" alignment for the mating parts.

                            I did not realize those would be threaded holes. Those are a little more forgiving of misalignment than close-fitting holes on rods, which is what I thought you were dealing with. (Actually, I first thought you were dealing with a continuous round rod spanning both lugs, but realized that was a dumb idea, because the file rod would have to go right through the middle of it.)

                            Glad to see you are back on your feet, but be careful mixing medical stuff and shop stuff.

                              Here's a photo illustrating what I mean by aligning the holes with a threaded rod held in the tail stock drill chuck:

                              It's just some 3/8 (10mm) hot roll, threaded into the existing hole that I just did.
                              Figure the tail stock and the spindle are pretty close alignment by themselves,
                              so anything I line up off that relationship will be good.

                                It feels good to be back at it, but definitely gotta be careful with the pain killers. Thankfully I'm able to wean myself off of those pretty easily.
