The oil would leak out and run down behind the front cover so it wasn't immediately obvious.

    The solution was to remove the headstock top cover and replace the "rubber" gasket with some proper cork gasket material. The lathe was oil tight after that.
    I have a Metalmaster 12 x36 circa 2007 that came like that with a wonky gasket plus free metal shavings and lumps of painted casting sand in the sump. Great fun to remove.

    The gasket I used was the automotive cardboard and has well well to this day.It was a left over and was easy to mark cut and punch holes..

    I don't know why I did it,but please do not be like me and spin the lathe over with the cover off.

    I can tell you that the means of getting the oil towards the top of the headstock gearing,works exceptionally well. There is one place in the underside of the corrugated roof that should not rust as it is well lubricated.

    A little oil on the ceiling is bugger all to worry about Graeme. Somewhere there is bound to have been a bloke with his dreadlocks tangled in his chuck so yours is minor in comparison

    Yep, spot on pipeclay, forgot to mention that..... also Steve, when you have the box cover off, check out all the corners of any metal gears, shafts etc to see if there are any burrs which you can stone off...chances are there will be, especially on the extra change gears you have...some were cut pretty rough on mine.

    Tellus 32 works for me and I use it both in an oil can (that does the lead screw, ball oil points as well as drizzle over running gears and the running lead screw) and an old plastic spray bottle which has a hard time spraying but does with plenty of grunt applied, you don't need much when it sprays.

    A spray on the lead screw will lead to lots being wasted so just run a drip along it as it rotates. I only use the spray Tellus when I need to coat something with thicker oil such as the gears but I don't use that as much as the oil can because when you spray it inside your drive gear housing box you run the risk of contaminating the drive pulleys and belt along plus getting oil on bits that don't need it such as the motor shaft...use a can there

    Only other lube I use is Inox liquid....it's a light machine oil which I buy in the 4 litre bottle of liquid (not the aerosol can). That comes with a separate 500ml capacity adjustable spray bottle and I use it to coat the ways, bed and all exposed metal surfaces. I always spray it over the ways when commencing and again when done for the day.....occasionally the cat gets a squirt too just for rust prevention

    Living near the sea I get pretty nasty salt humidity, Inox is a very good short term anti rust treatment on all exposed metal including the lathe. It is not suitable for any load and should not be used so.

    There are a lot of knowledgeable folk on this forum and no doubt every one of them has their own preference for lubricant and the processes they use to keep their iron running. This is my method, it's probably not the best nor the cheapest, but it's works for me.

    Good luck ...Lee

    Hi All,
    To get to the bottom of the spindle gearbox and suck out all the crap oil/sand, you may be able to use one of these devices (if you have a compressor), it can also be used to flood spray protective lube/oil over machinery out in sheds )

    or one of these;
