    Default Lubing a Myford Super 7?

    I've owned this lathe now for over 10 years and am still frustrated by some of the stupid oiling nipples. Lubing the main head bearing is ok, you simply fill an oil reservoir. On the other hand the rear bearing has an oil nipple which I attempt to refill in vain using a small hand pump and in this process most of the oil ends up on the outside. Thoughts anyone?

    Hi,
    These oilers might help, they are sold for the Myford lathes but there is no reason they can't be used for yours.
    If it's a on the side of your lathe you could put a 90 deg adapter on it.

    The Myford oiler is what is termed a pom pom oil gun. It has a concave depression in the end that fits on the nipple and you just push the gun down and it pumps the oil past the little sprung ball in the nipple.
    These are available from a number of industrial out lets. They are made by Teclamet.
    For the sprung ball oilers I use a oil can with a modified needle on the end of the stem to push the ball down and then pump oil in.

    Dave those oilers are for the ML7 Myford head bearings and wont fit the Super7 Myford .
    The Super7 rear bearing oil nipple is a 2BA thread (IIRC).

    I am using the 'pom pom' oiler. Doesn't work for me...Maybe I should have whipped the pump nozzle off years ago and modified it with a bit of lathe work. I tend to adopt the bad habit of non-lateral thought. I like your idea of the modified oil can. Is that a thumb pump type can?
    And yes Dave, it's a 2BA but I could probably modify something to suit.

    Yes a thumb type oil can ,I bought at the local auto shop ,it has a flexible plastic tube with a wire inside so you can bend it and the tube will stay where you put it ,on the end is a small brass tube that you can push the oil nipple ball down with while you pump the oil in.

    The problem with the Myford nipples is that they will not seal in the nozzle of a standard pompom gun. I never had an original Myford oil gun so I can't really comment on how well they worked but I got sick of oil running everywhere when I used the one I had.
    My solution was to replace all the original Myford nipples with standard ISO grease nipples which fit the pompom gun perfectly and hey presto, no more leaks and I know the oil is getting where it needs to be.
    I waited until I had the lathe pulled down because I needed to retap all the holes to M6 as it was next to impossible to get nipples with 2BA thread. I could have got them from the UK but I didn't feel the considerable extra expence and time was waranted.
    Cheers,
    Greg.

    Hello Doc.
    I replaced the ball nipples on my mill table with grease nipples and bought a small grease gun from Supercheap. I made a plug and soldered it on to the bottom of the grease reservoir and now it pumps oil . Works fine.

    Default Modified grease /oil gun

    If you use a modified grease gun be sure you have one with a ball valve tip.
    You know why.

    But mine leaks anyway.

    I am still using the original Myford supplied oil gun with my 25 year old Super 7. While the gun is not perfect I always hold a piece of clean cotton rag between the nipple and gun, this helps to seal the joint between the gun and the flat topped myford nipple which looks like its just designed to leak.
