    Hello members, thanks for allowing me to join your group.

    I have a Maximat V10P, I guess its around fifty years old, plus?

    It belonged to my good friend who had his own pro engineering shop and kept this one in his home garage for making items like fishing reels, he was a really good engineer! when he passed away I was able to purchase the Maximat from his wife.

    As I have had it some time now I have sorted out certain issues and serviced and cleaned it, it has the one issue though, if I have a shaft in the chuck and run a machine tool along it towards the chuck the run out is 0.003" in only 1 9/16" which is way too much.

    I have tested the run out from both sides of the shaft being cleaned up, cutting from the front it will cut deeper towards the chuck, if I then machine from the other side of the shaft it will undercut and by the same 0.003".

    I see no way to adjust the gear head shaft, or the entire gear head box either, is there a fix for this problem?

    Note, the beds do show wear but that will take the tool holder lower, which should not be an issue?

    Has anyone got any ideas please?

    Regards

    There will be some way to adjust the headstock, but it might involves scraping or shimming.

    First step I'd suggest is finding a parts diagram, so you can see how the headstock attaches to the bed.

    Thanks, I do have the exploded parts page, it shows that shaft and with a bearing each end, no shims, I did read about paper shims, which makes little sense?

    My steel square on the beds shows the traveling bed to be spot on, so it is the head stock shaft.

    I have tried to up load the drawing of the parts but it does not work.

    Hi
    Have a look at this
    https://www.youtube.com/watch?v=dMP_F9wvb1c
    ideally a No3 Morse test bar would be used.
    I had to settle for the Emcomat 7 when i bought my lathe, the headstock on your machine should be in perfect alignment with the bed as it locates on the V section of the lathe bed, but it might have some clearance so it can be shimmed, however i don't think this is the case. Emco machines are of good quality and were priced accordingly.
    Regards

    Thanks, that is a very good video!

    However my situation is that the headstock is not true to the beds, its pointing out towards the tailstock.

    Anyway, bit by bit and with advice from forum users I am making improvments, today I removed the twist from the tailstock end, it was low at the back by over 4mm!

    is there any clearance between the interface on the v section ie between hedstock and bed, can you get a shim between the bed and the headstock V section. do those two small screws allow you to move the headstock ?

    I have managed to up load the drawing of parts in my opening page, the main shaft has a bearing on either end, I see no sign of a shim or adjustment.

    Thinking this issue a bit more, shims would not help in my case, as its more a problem with making the headstock move right or left, in my case when viewed from above and looking towards the tailstock I need it to move to the left of the machine?

    Thanks on your comment.

    The lathe cupboard was not bolted down when I bought it, seems that my late friend saw no reason to do that?

    It is mounted on two thick steel blocks and one each end of the machine, a single bolt in the center keeps things in place.Click image for larger version.

    The traveling bed is spot on with the rails that it fits on to, all parts were removed and cleaned, oiled and work really well.Click image for larger version.
