Old Myford spring oilers

[CharlyParticipant @charly]

Hi there,

Could someone tell me how to remove the old spring oilers from a Myford?

Thanks

Hi Charlene,

do you mean these type?

Regards

[CharlyParticipant @charly]

Yes I do.

I removed some last week by using a drift from the underside. The drift just fitted in in the hole, and all but one responded to gentle tapping. The awkward one had to be pressed out in the vice. There was minor damage to the undersides, which are chamfered down to almost nothing, but they still work OK after being gently tapped back in from above.

Hi Charlene,

If you can't get access below, I have seen them removed by drilling the top to release the ball and spring and a stud extractor used in the bottom hole to pull the shell out. It is always possible to drive the body through and remove the remains from inside the casting, or collapse the shell from the top and get a pair of long round nose pliers to pull out the remains, or carefully drill out the shell.

At a fiver for 20 these oilers are not exactly expensive and you can always sell the spares on eBay, probably at a profit

Regards

Terry

Hi Andy, the problem is that it is that I can't get a drift or anything in there as it is on the swing head assembly. I think I will get a set of extractors as it seems the best way to do it. Thanks for your advice anyway.

Hi Charlene,

Let us know how you get on, with pictures for all of our benefit if possible. These sort of exercises add to the communal knowledge.

Best regards

Remove the shaft then punch the ball and spring out thru the bottom.

Then tap the hole that's left, any suitable size and use a long screw with a packing piece, old socket works well and pull the old oiler body out.

In all fairness to Terry do not use this type of extractor as all they do is wind into the hole and expand the body so it jammed tight. For these taperered extractors to work the body would be that loose it fell out.

Hi John,

I did say a small extractor into the bottom hole. Perhaps I should have emphasised that I didn't mean using it into the external shell. I hvae seen the ball and spring removed from the top by drilling, our maintenance technician did it regularly – we had about 40 lathes, millers, drillers etc which needed these oilers replacing from time to time by drilling the top rather than punching through, there was a more substantial base left.

Interesting to see a different approach. The shells of the oilers we used didn't appear to be substantial enough to be tapped. One is never to old to learn.

Best regards

No Terry i probably wasn't clear enough.

You punch the ball and spring out to make room then tap the top hole out which is smaller than the body.

 

Got to shoot out now, just done a quick sketch but the damn scanner wants updated drivers, will do it when I get back

The oilers described are fine but let in small particles with the oil !

Does anyone recommend replacing them with spigot type oil/greasers. It means tapping the hole for the thread and best done when dismantled.

Just a thought.

Hi John,

The Oilers we had, had small bottom hole i.e. (not as rude as it sounds )

Here's my sketch.  Don't blame me – you started this sketch thing

I see the advantage of your approach though and would recommend it.

Best regards

Terry

I have a couple of photos of how I did it. Don't know if it will help anybody, but it came out very easy. With the first oiler the ball was already out, thus the reason why I want to replace it. I tried to clean it and I pushed a bit too hard. With the second oiler I just tapped the ball down with an appropriate sized allen key.

To remove the oilers I turned the smallest extractor into the top hole, probably 5 to 6 turns and then used a vice grip (sorry, can't remember what you call it here, that's what we call it in South Africa), gripped it and tapped the bottom of the grips with a small rubber hammer. It came out as easy as pie.

Photos are a bit blurred, sorry.

[TerrydParticipant @terryd72465]

Thanks for that Charlene, and well done. Very diplomatic to combine two approaches.  Don't worry about your photos, I often get the walls in excellent focus when taking pictures of jobs!

I note your cri de coeur' in another thread, I obviously can't help with any training, being based in the UK. I don't know if you are familiar with the MIT training videos, there are some good videos from MIT (one of the best technical University schools in the world) aimed at supporting University students in their project work. They cover a wide range of machines and techniques. Not as good as hands on training but worth watching if you haven't come across them before.

Here is a sample, the first lathe video in a series of three. The videos cover basic benchwork and milling as well.

Best regards

Terry

Thanks for that Terry. Sorry for the misunderstanding, I am in the UK – have been for 6 years now, but still trying to get to terms with the local names for various things. Thank you very much, will definitely have a look at the videos.
