    Well he's a lucky fellow then. Forgot to say that the tapholder should be a releasing type.
    No, he's not a lucky fellow because he spoke to you,any idiot can speak to you,(had to,just had to). He is lucky to have dieheads.

    I think most of the die head stuff I have will be too big, I'll dig em out and take a look when I get a mo.
    Have turned a gage for the spindle threads, it's about as nicer fit for the cap as could hope for, I intend to keep the same size/tpi but will make it longer, leaving say .100" on the nose. Is gonna be one skinny sleeve with around .040" under the threads. I've some EN19T that I plan on using.

    Thats a happening little capstan lathe!

    My Wade is a similar size, also 3/4" shank. The smaller 2 sizes of Coventry die heads should fit yours just fine, I opted for making a new shank for my Conventry, an ebay score in fantastic shape but had a 1" shank.

    I've found drill chucks take up a lot of axis, my prev owner liked them so I have a pile. What works well as a quick expedient is to take a short length of 3/4" TGP or at least pretty smooth bar, drill it through for the size of drill you want and fit a grub screw that is below the surface when clamping the drill. Then you fit the assembly directly in the capstan bore; gets you a minimum length projection, with the cost of ending up with lots of the buggers in the toolbox and you have to find the one you want. Its also not a floating arrangement so quite sensitive to misalignment of capstan to spindle bore.

    I'm a fan of the Boyar Shultz box tools, though have a few Brown&Sharpe also. Its a shame about your spindle nose, OTOH when using the machine for conventional turret work I've not yet ever mounted anything to the spindle threads; all in collets.

    You have any preferences for coolant? I run cutting oil diluted with 0W spindle oil so it pumps and drains well. It helps with repeatability, particularly with dicey tool setups, but does tend to make a mess.

    Thanks for the info Greg. Unfortunately I need the cap to use the dead length collets that came with the machine. Although open to suggestions for other collet setups etc.

    Cheers

    Yeah, looked more closely after I posted- that cap needed for sure. I think its well worth getting fixed up to work properly, my Wade uses conventional pull-in collets which always puts the workpiece at risk of pulling back a bit when the collet is closed. It usually requires a hand to ensure the piece doesn't creep away from the feed stop and somewhat fussy adjustment of collet tension.

    I mounted a "0XA" sized import toolpost w/ holders on the production slide, helps to put the form tool on one end and a parting tool on the other. Quite envious of the Hardinge spindle-mounted parting slide, there are never enough tool positions lol

    Well, its on there. I cleaned with their 7063 and slipped it on with 'a rotating action' using Loctite 638. I was gonna try and do a couple test pieces, but decided its much its much easier to just blame Sami if it dont work



    Ive seen a Britan lathe that has 1 1/4 through the spindle, im trying not to buy it honest

    My shoulders are broad.

    if Demon thinks/finds a capstan's a bit confusing, .....a Britan will bend his brain out of shape - for starters they run ''backwards''

    What material do you intend to cut with your phone?
    The Britain is/was a nice machine and once you get your head round it you will love it. Go on,go and get it.

    He's bigger than me and I can't run as fast as I used to, so I will NOT.

    Have been mad busy last couple days.
    Just had a quick look at the rear bearings, opposing ball races that take care of end loading and float. Seems I need around .007" between the outer races to tighten things up, ill make a stack that gives me some room either way.





    Anything that improves what I had is welcome

    Speaking to an old customer who became a friend today. He is setting a Britan to centre(yes CENTRE) drill and tap some old railings which have rusted through at the bottom. For those of you that know these are for houses which have a basement in the CENTRE of London. Trust me, you couldn't afford the railings, don't even think of buying the house.
