  • I gotta take the chance when I have vacation, otherwise my day job keeps me from making it to these places when they are open.

    Anyway after the spindle reassembly I clamped up the spindle by the inner shaft in the vice and put the indicator on the outer spindle itself, then I pushed and pulled on the spindle in both directions. No real setup of the lock nuts was needed aside from my inital tightening. I got 4 microns or there abouts and that's good enough, the manual says only 1 micron but that's difficult to achieve and I was adviced to aim for no less than 2 microns, but 5 microns should be fine. The thrust bearings need some clearance to live.


    Then I reassembled the vertical head, testing the quill function and it's now smooth as butter compared to before. It's too bad some of these parts are really worn and busted, tried to clean them up best I can.

      Some of the nicest work I have seen Dennis. JR

        They'd need a lapped finish and be a perfect cylinder and matched to an incredibly small tolerance. If another human being can do it, so can you if sufficiently motivated and inclined....but it wouldn't a simple or quick undertaking....and you've still got the underlying problem (which imo is poor design). I thought of it briefly but instead I'm pursuing making a new spindle. Its still a big project, but doable with little mystery and is low risk.

If you do come up with a source for high precision needle bearings to specific sizes, that would be good info to have. 15 microns is about 1/2 a thou, I have no info one way or the other be intuitively it seems like a lot of play in a spindle? I do not like this format of needle bearings at the bottom, no way to get a proper preload, at least not 15 micros worth.

          If you have or can borrow a micron dial bore gauge, one revealing test is to check along the outer race, it should be a cylinder, but can end up tapered with wear
          There should be no preload on Deckel needle bearing spindles. There would be no way to control it even if you did achieve some initially. The assembly is too stiff and thermal expansion would swamp any adjustment. You can get finely graduated sets of needles from Franz Singer in Germany. This subject has been discussed many times on the PM Deckel forum.

          • I decided to go on ahead with reassembly of the head stock today.



            Also completed reassembly of all the other components to the vertical head and plugged the hole on the side again. I left it unfinished instead of painting it.



            Then I proceeded to work on the horizontal spindle as it needs to be installed before I resinstall the long reach vertical head.



            Was stuck pretty good








            Removing the rear bearings:





            Taking note of the placement of the components and orientation as I lay them out.





            I didn't really photo the rest, I cleaned some more and I greased all the bearings with the same grease and reassembled. Then I set the axial play with the lock nut until it read 6 microns or .0002" I think that's enough, the manual did not say what amount of end play there ought to be.

              understood, and that was the point...I think a bearing arrangement that you can set a preload on and where bearing replacement means a new inner and outer race, is far superior. thanks for the Franz Singer suggestion, I wonder if they have them small enough for my Aciera? I'll have to check it out.

              Dennis I don't think you have any issue with yours. I'm just in general negative toward that arrangement. The mill is looking very good!

              • Just upgraded my Mig welder. Picked up a Lincoln 180c with cart, bottle, and 25ft extension cord for $650. Then he threw in a wurth autodark welding helmet in too . Should be able to sell my little Hobart 120v for $250-300, so not a bad upgrade. I didn't want a BIG one for home as I've only got 40 amps, and most big stuff I just stick weld, or take to work. Just wanted something in the 180-200 class for quicker welding of tubing etc up to 3/16-1/4". Plus I can run a spool gun with this too, which might be handy for meatball surgery on some boat projects lol.

                First project is to build a mega cart to hold the mig, Plasma and my tig welder and bottles.

                  • No machining, just working on a project for my bil. R&R the shower in his mobile home. The walls were covered with a coated Masonite type material that did not hold up well to the moisture. The bottoms of the panels were rotted away, so I had to strip it all off and start anew. This is a weeks work so far:

                    Installed Wonderboard



                    Applied RedGuard sealant

                    Getting the tile on.


                    Hope to finish the tile on Monday and then install the new door.

                    • Had to make some deep cuts in some 2 x 4's the long way. Had to get out the old (1950's) Porter-Cable Speedmatic BK-10 saw. I think this thing weighs 28 lbs. It worked well but took about a 1/4" kerf lol. I think I still have the instruction book for it, and it shows a carpenter reaching out and cutting rafter tails with it. That was back when men were men lol. Note the motor works on AC or DC. This is a 10". They also made a 12".

                          My Paternal Grandmother was from Oslo. I've always wanted to visit Norway, and now your pics make me want to even more. Beautiful backdrop. Thanks for sharing.

                          • Had I don't know how many people over for a party last night, went from 5 PM to after midnight..... Have barely been in the shop for some time getting ready for it, now as soon as we clean up the place, I can relax and get some shop work done.

                            Only shop work done recently was making a part for a Weedeater, that was NLA from the company. needed to fix weedeater to trim up the lawn. And then, after I made it, I found that another essential part has disappeared ! Nobody here will admit to anything, but I suspect that it got "cleaned up", i.e. tossed, during party prep. So the newly made part was of no use, as the missing part is also NLA, and I have no dimensions etc to go by. Grrrrrrrrrrr

                            • The long reach head and vertical head is now reassembled as well.





                              Reassembly of the vertical head was tricky, all the t-nuts fell to the bottom of the slot. I had to inject grease around the t-nuts to hold them in place, and then I had to make short lengths of threaded rod that I put in the t-nuts, otherwise I don't know how I would've been able to get all the t-nuts lined up. After I had the bolts through I could just remove them and put the regular bolts back in, the grease around the t-nuts kept them in place.
