Lathe suggestions?

[routercnc]

Well I've had this lathe for just over a year and couldn't be happier with it. DROs have been faultless and were well worth fitting.

Only thing bothering me on the lathe is that the carriage has a very slow oil leak. After a year of ownership it stopped dripping about 2 months ago, and the oil sight glass showed it was empty. I bought some more oil at a recent show and have finally got around to trying to fix it.

First problem was that access to the oil plug was quite tight - not enough space for a hex key. Thought about grinding one down, then decided to make a tool. I had a round aluminium bar with a hex shape on it (from another job) and machined a small hex on the top:



Then held the larger end with an adjustable spanner:


And into the oil grub screw:


Last bit of oil came out . . . .


Along with some free grit presumably from the casting . . .


Cleaned it up, put around 5 rounds of PTFE tape on and tightened it up.


Filled up with fresh oil and . . . . .
. . . it still drips (slowly)!

I might not get on this again until next week end but anyone else had this problem? More PTFE or am I missing something?
