    The top two layers of the table (above the ball bearings) can be removed by taking off the three retainers (1 front, 2 back) that run in the slots on the edge of the table, it will just then lift off. Take some placky bags as taking off the table will expose a lot of loose ball bearings that you will have to collect.

    I was wondering if I should remove the table. Looks like I am taking some tools with me.

    So I picked the grinder up yesterday and got it into my shed with no major issues. It weighs quite a bit which is handy as it won't fall over.

    As for condition it is hard to tell yet. The X direction was difficult to move and the reason for this was clear when I took the table off. The ball ways were full of dirt and grit. So I have cleaned up the balls and their keepers and am in the process of cleaning up the table which might need some sort of chemical bath, suggestions welcome. I was thinking of taking it to an engine reconditioners to have them soak it in one of their baths (would that be safe with the ballways still in place?).

    My plan is to take of the Y slide and clean the grit out of that and put the whole back together for long enough to check how much inaccuracy the years have worn into it. The serial number is 3A-663 so I am guessing it was made in 1966?

    If with a dial indicator it doesn't have too much wear then I will get cleaning the whole thing and refurbishing the things I have noticed needing attention so far (new bushes for X axis gear shaft and maybe a new shaft, new leadscrew and nut for Y axis).

    Default More worn than I hoped

    So I did clean up the x and y slides and stuck a dial indicator on the table while i moved it around. The x is worn about 0.04mm in the middle of its travel (see video) and the y has 0.02mm variation across the table. But it think some of this is a symptom of the x ways wearing unevenly.

    So the question is do i get the x ways ground and find a local who likes scraping and is skilled in that area to tizzy up the relatively short y ways?

    Hi Eric

    I am not sure what you plan to use it for but if the idea is to sharpen end mills and some lathe tools I would find a spot at one end of the bed with modest wear and use it as it is. You only need 75mm max of travel for an any of the end mills that I own. If the wear actually becomes a problem I would then do something about it.

    Regards

    That test does not tell you the condition of the ways.

    It tells me something I didn't know before. Have you got a suggestion for something that will tell me more?

    Hi Ian,

    I was thinking along the same lines but then there is an opportunity now to have the ways ground that might not exist in Adelaide in a few years.

    It all depends on how much I get quoted when I take the parts to see the grinder tomorrow.

    Hi Eric, sounds like a lot of trouble to got to, trying to fix it for me . Honestly, great to see that it's in reasonably good condition. As you say, a grinding option might not be available in a few years. If you find the quote a bit much, get in touch with Mal, as he has a contact for grinding and scraping the surface. Transport cost might be the killer though, unless you know someone going there.

    Kryn,

    All you have to do is outlive me and it is yours. Unfortunately for you I am ten years younger and have wife who won't let me die as she hasn't finished with me yet.

    I am pretty sure I could use this as is for most grinding tasks but I only intend to fix it once. Already It needs a new leadscrew and nut for the Y axis and the bearings in the shaft that drives the X axis pinion have too much play.

    I took the table, sub table, and saddle to Precision Grinding here in Adelaide today. I will see it again in about two months. I will get it back with The V ways reground, the top of the table, the top and bottom of the sub table and the bottom of the saddle all reground. From there I will scrape in the Y on the knee and the Z looks pretty good to me.

    So I have a couple of months to get the other parts sorted. I will post some pictures when I get the parts back.

    Snapchat-767977622.mp4Anybody know how to get this apart? I was expecting some way of holding the shaft still. C-spanner or otherwise. There is nothing I can spot. I have attached a video.

    What's on the other end, is it the same as shown on the video?? What about using a strap wrench to hold the shaft, while you undo the nut??

    Hello Eric,

    Here are two photos of the No. 3 spindle assembly.

    Strap wrench kept slipping on the shaft and when I put it on the pulley the pulley just span.

    Thanks for the photos Bob. I am going to try using the not at the non wheel end of the shaft to hold the shaft still while I get the parts at the other end off. It should work as that is a RH nut so it will just get tighter as I undo the other end. Well at least I hope so.
