Press Button Oilers

[ChrisHParticipant @chrish]

I have an 8mm press button oiler on the lathe that is ‘broken’ and needs replacing.

 

Does anyone have a good suggestion on how to remove it without damaging the bit of the lathe it sits in?  The oiler seems to be a very tight fit in it’s hole.

Find a tap that suits the hole, cut a thread and then use a bolt to pull it out. ARC sell new ones. Or if you have a small stud extractor use that.

Thanks for the reply – I was thinking of using a stud extractor, the ‘cut a thread and use a bolt’ is the next progression onwards.  I will see how it works!

Hi Chris,

 

Just a thought. You could cut off the ‘head’ or flange of the oiler by using a countersink in a hand drill similar to cutting the head of a pop rivet when removing.  Then if necessary carefully drilling out the body of the ‘cup’ in stages until the shell is thin enough to be able to collapse inwards then use a pair of snipe nose or round nosed pliers to pull out the remains.

 

Regards

P.S. the hole made by the countersink would release the ball and spring inside.

P.P.S  The taper on an extractor may expand the body and jam the oiler perhaps?

This morning I had a go at getting the oiler out and thought that the stud extractor was the easiest method to try as a first go.  I had tried this some time ago without success and given up, but obviously I wasn’t trying hard enough, as a good go this morning with the extractor and out it came.

 

So, to Jason and Terry – thanks for the advice.
