    Sounds a bargain, don't know much about mills but am I correct in thinking the quill is the bit above the chuck that moves the chuck up and down, bit like what pillar drills have? So is it just a case of raising/lowering the table?

    are Ajax a similar size to the Marlow and Harrison or are they larger?

    This looks a nice machine

    How do any of these 'smaller' milling machines compare?

    Both nice - the Marlow is a bit smaller than those.
    And yes you just move the knee up and down - fine for most milling but for drilling there is no feel.

    How about this if you are on a tight budget?

    If I hadn't just bought the Marlow I would be very tempted

    Over £2000!!!
    I told you small mills go for silly money! You could get a good Bridgeport for less - or a nice Harrison.
    R8 tends to be Bridgeport. That mill was probably a morse taper. Most people go for an ER32 Chinese collet chuck - mine was £67 with 18 collets.

    I paid £180 for my Elliot Pallas V1.
    Ebay is the place. Size puts people off and mine was a lot more difficult to move than expected but ingenuity and a few friends help.

    I did too, but am struggling to get the right M10 TPI details so that I can make a drawbar. 'Standard' M10 threaded rod won't screw in, nor will M10 fine1.00 rod. I'm in contact with Banggood but having difficulty explaining, what with language differences.....:(

    I'm beginning to wonder if I was sent an Imperial chuck in error. What thread is in yours, Vince?

    My metric collets have unc drawbar.

    Do you mean your metric collets fit your existing drawbar?

    My metric collets fit the chuck, but I want to make a drawbar. M10 rod won't fit the end of the MT2 taper.

    Ah I see your confusion. My collets fit direct to spindle and drawbar is threaded 7/16 unc a common thread for them.

    Worth a try. Very close to m10

    I've put it to BG that I might have got the wrong chuck :rolleyes: Mine was advertised as taking an M10 for a drawbar, ain't so......:(

    Standard M12 on mine MT3.
    I suspect also 7/16th possibly - find/buy a bolt and find out.

    Can someone just clarify for me, if you have say an r8 mill, you then get an er32 collet chuck which has r8 on one end to fit into the mill and then you put the milling tool in the appropriate size collet gripped bythe er32 chuck? If that makes sense? Or have i got it all wrong?

    Would the other option be to buy specific tooling to fit the MT3, r8 etc mill spindle?

    Correct.
    Or buy individual r8 collets to fit in the spindle taper. Useful on machines with low headroom

    Great, thanks, this is all new to me, but its good to learn what's what.

    I have seen mention of r8 spindles being preferential to Mt2/3? as they are easier to remove, but how you guys do it with the collet chuck it would not matter as you wouldnt need to remove it each time you changed the milling tool?

    Is the drawbar a threaded rod to pull the collet into the chuck of the machine, and some collet chucks use large nuts over the end of the collet to pinch it?

    Draw bar is fed through the top of the spindle nland threads into the taper of the tooling. (Chuck collet boring head etc) to pull it In tight and stop lateral forces pulling it out during cutting.

    Takes 30 seconds fo me to change from a collet to chuck. Probably no slower that a er collet chuck.
    Personal preferance I suppose.
    Less stick out from the spindle can only be a good thing though.
