Lubrication oils

Just to answer your query about swarf sticking to gears.

Because I haven't used open gears for many years, I had forgotten completely about that problem, but when I used to use my old Myford ML2, which did have open gears, I never found it a problem, as chips never seemed to go towards that direction.

John,

I've seen swarf get into the spindle bore and work its way to the left and drop down into the gear area. That was with my 9x20 lathe. I haven't seen that problem with my Vectrax lathe to maybe it isn't an issue. I'll have to pick up some of that grease you recommended and give it a try. Is something like this the type of lubricant you are talking about?

Thanks for the tip.

Ed,

Thats the sort of stuff.

Usually when it is sprayed on, it sort of 'bubbles' like an air leak, but it soon gets all over the teeth and then sticks like glue.
Just imagine what speed a mo'sickle chain runs at, and it still sticks to that.

Just out of interest - here is a picture of the inside of my lathe spindle. The groves actually convey the chips back to the chuck end whilst running. I put a ball bearing in the middle one day to see which way it went.

   

Mind you, the back of the spindle extends past the gears, which also helps keeps the chips away from the gears.

Mayhem,

That is the weirdest spindle bore I've ever seen. I wonder why it has a spiral cut in it like that?

I posted that pic on H-M a while back and one theory that came up (other than chip evacuation) was to dampen harmonics.

Now that's what you call a threaded spindle!

On my mo'sickle it can run up to about 5,000 ft/min chain speed, not bike speed which can be about 3 times that, or slightly more... Not all the time, though! At that sort of speed it would need re-lubricating every 2 hours or so, a fair exchange ;) Probably explains why a chain and sprocket kit is around £100, considering the stresses involved?

It's also good if you need to lay up a machine for a while and want to prevent corrosion - sticks like the proverbial to a blanket and a £15 can will easily cover all the working surfaces on a fair sized machine, it comes off easily with paraffin when you want to get the machine back up and running, or works well as way lubrication until you've re-oiled it! I use it on my change-gears, too.

Just my ha'pennorth,
