    D1-6 Camlock Spindle Nose does it have a standardised internal taper?

    Thanks everyone for the thoughts, especially the links to the tapers. For anyone who's curious or follows at a later date: I finally got around to measuring up spindle a more accurately and looks like it is a short segment of MT6 Morse taper, but it looks like its not a great surface finish...

    D1-6 Camlock Spindle Nose does it have a standardised internal taper?

    Interesting to hear everyones take on this, thanks for the thoughts and ideas. It really is minor surface rust, (and perhaps more cosmetic a consideration) I definitely wasn't thinking about re-shaping the taper, just the very lightest of clean ups but sounds like this might be more dangers...

    D1-6 Camlock Spindle Nose does it have a standardised internal taper?

    I have an old Nuttal Lathe with a D1-6 Camlock spindle for fixing the chuck but I would like to use the internal taper for a few higher precision projects and I would like to correctly identify the taper if possible (?) and if it is a standardised taper(?) re-grind the internal taper before...

    What Steel to use when? Tools Steels Vs Low Carbon etc

    Not that I have found so far, lots of little steel dealers but mostly structural steels. No one whom tackles the full range of tooling & materials McMaster Carr does. Bit of a shame, but maybe they will one day open an Australia arm, probably would do solid business if it kept prices as...

    What Steel to use when? Tools Steels Vs Low Carbon etc

    It does sound like a solid tip and looks like a good read for this kind of subject matter. Regrettably from a quick search what is $40 your end by the time it gets to the land of OZ and is converted to Aussie Pesos is $173AUD + $16.90 postage (yikes) :o but I definitely will keep my eye out for...

    What Steel to use when? Tools Steels Vs Low Carbon etc

    Thanks everyone for the thoughts great to get so many considered opinions. There is some wisdom in this approach that can't be denied, when I make tooling for myself I tend to over think it a bit hoping to solve the problem once and try never to revisit it. I also find tooling useful to learn...

    What Steel to use when? Tools Steels Vs Low Carbon etc

    I'm looking into material choices to make a couple of draw bar style tools for my lathe: A headstock centre boss MT3 (Morse Taper 3) adapter for a dead centre for turning between centres with a draw bar setup A headstock centre boss mounted ER32 collet chuck Possibly other drawbar style chucks...

    To Grease or Not to Grease? (That is the Question)

    Just an update for anyone who's intrigued, I managed to track down a manual for the Nuttal lathe and it recommends a mix of grease and oil (I'm a little surprised also). For the most part I have been sticking with oiling almost everything because I'm the only one using the machine and so any...

    To Grease or Not to Grease? (That is the Question)

    Backgroud I have been working through a quick restoration of a Nuttall Lathe for personal use, and come to the stage of reassembling various components and I am keen to make sure they are lubricated correctly as they are reassembled. A number of the components have zerk nipples for lubrication...

    Colours & Paints - Nuttall Lathe

    Interesting, what is the objection to hammer tone? There is a hammer tone Dulux epoxy based Enamel paint that I have used previously and it is fairly forgiving on surface prep easy to apply either with a brush or spray. Colours can be a little loud but it wasn't off the list especially for the...

    Sizing VFD for Nuttall Lathe 1phase to 3 phase

    Thanks for the thoughts, I'm not 100% clear on what you are saying hear but I would say I have a two speed gearbox (High & Low) plus a series of stepped gear setting in each range (3 positions each). --> From what you are saying --> I need something bigger than 3HP (eg like the 5 HP motor...

    Colours & Paints - Nuttall Lathe

    I'm chasing some advice & opinions on paint removal & paint selection and paint colours for a 1960 Nuttall Lathe. All tips, tricks, pictures of restored machines & colour codes would be appreciated. Whilst I understand this is very subjective I was hoping to avoid any pitfalls or common...

    Sizing VFD for Nuttall Lathe 1phase to 3 phase

    Thankyou there is a lot of information in your post, and I'm not sure I followed it 100% but one point I would like clarified is the idea of sizing a VFD (and/or a new motor) for the "load" not the rated HP & current for the existing motor. Whilst this sounds reasonable as a way to use a...

    Sizing VFD for Nuttall Lathe 1phase to 3 phase

    Attached are a few pictures of the motor, my apologies its hard against the wall and a little tricky to get a good photo. (presumably also to get out the motor but we will cross that bridge when need be.) The name plate gives this as a "Frame: C213" As...

    Sizing VFD for Nuttall Lathe 1phase to 3 phase

    I was worried I might have it backwards or upside down. :confused: So from what you are saying in a star configuration the line voltage between nodes would be 400V (or say 240V in my supply case) but the phase voltage would be less across each coil 240V between each node and neutral point in...

    Sizing VFD for Nuttall Lathe 1phase to 3 phase

    Thanks for the reply. My electrical knowledge is fairly rusty so I will try to clarify my thinking a bit I was under the impression that the configuration of the coils could be changed from 'delta' to 'star' dropping the voltage from 400V to 240V. From memory on most motors this can be achieved...

    Sizing VFD for Nuttall Lathe 1phase to 3 phase

    I hoping someone could offer some insight on sizing a VFD for an old Nuttall Lathe. Any advice, help, tips, tricks, pointers or links would be appreciated. Problem Sizing and selection of budget VFD for single phase 240V to 3 phase conversion for Lathe and Motor outlined below. Ideally with a...
