1/4" " angle Drive In Hydraulic Grease Nipples

I have a need for 5 of the above for my Denham Junior lathe, I've searched on Google and only found 1 trade only supplier that has them (i have contacted them in hope) but does anyone have some or know of a supplier or even a work around?

Thanks

Roger

When I was at work and we needed one I ended up buying a selection box of about 100 types as it was cheaper than sourcing one but as a company we only bought things from a few selected suppliers. Ebay on the other hand have plenty. Try a search for BSP grease nipple and you will find lots of thread sizes including UNF and metric as well as BSP

Thanks for the reply Martin but read the title please, I stated drive in, threaded ones are not an option.

IF I understand correctly You want a 1/4" drive in nipple ?  What angle 45 or 90 ? Nipples are available in many threads, 1/4" BSF, and UNF 5/16" BSF & UNF, 1/8" BSP, 6,8,&10mm x1. Why not tap the hole? All these sizes are readily available. Or carefully grind the thread off a 5/16" one. Noel.

There is a good reason why I need angled ones and that is I don't have a straight in access to these positions so no chance of redrilling and threading for them, turning 5/16" ones down is an option but I just thought I'd see if I could get the correct ones first.

Something like these??

This outfit claim to do them too, but the part numbers aren't helpful

It seems that several places don't recommend angles drive in nipples, as the action of use can loosen them.
That said, I can see why you need them for your application.
The two firms above look like they supply, but if you're using them as oilers, rather than grease, the angles ball oilers in this catalogue might be worth considering

Are you sure they are grease nipples? Drive in lubricators would be subject to up to 4000psi, and that seems a recipe for disaster. Most lathes do have some sort of grease nipples, but they are usually oiled, not greased. The Smart & Brown model A has about 10 nipples which Mike modified to accept the nozzle of an oil can. Getting rid of the grease which was used in error in the past is almost impossible without complete dismantling and cleaning.

I have messaged Kingfisher but their box quantity is 2,000! they do say they do smaller box quantites but how small? Harrison don't do angled in 1/4"

They are called Grease nipples but are also used as oil lubricators, at least on my venerable lathe as original fittings

Roger

Would these style of push in button oilers work for you? I have bought both metric and imperial size of this type. The metric ones fit on the Taiwanese drill mill and the Tom Senior light vertical uses 3 different sizes of inch fitting ones. They are sold to fit the hole diameter, I got them on ebay.

Again they need a straight on connection and yet another pump gun

It really is a requirement for preferably 90 degree or 65 degree max angled lubricators.

Roger

Note that I've amended my previous post to add angled ball oilers.


There are other firms who supply angled drive fit in metric only, e.g. Ashon

The problem with the metric ones are that the 6mm is too small and the next size up (8mm) is way too big even to trim down.

I wonder if the M8 threaded ones could be turned down to be a press fit in 1/4 holes? The 45 and 90 degree ones have the nipple screwed into the base, so it may be possible to hold them for turning. If you have tried reducing the diameter of the M8 but the hole is too big, then a tubular sleeve could bring a turned down 6mm one up to 1/4".

Plus one for "The Nipple Shop"

Studying your question and answers so far I'd advise first determining the correct lubricant. You imply using grease, but is that right?

The pressure needed to pump in oil is far lower than that for grease, you also remove the heavy load from pushing a grease-gun against the nipple; and oil is the more likely lubricant anyway.

With that, you largely remove the worry about tightness of fit, and you may be able to make a suitable set of oilers more easily than trying to modify bought ones.

"With that, you largely remove the worry about tightness of fit, and you may be able to make a suitable set of oilers more easily than trying to modify bought ones."

I've already said that they are for oiling about 7 posts above, I didn't imply grease just that that is what they are called.

Oh, sorry - I evidently missed that bit!

No probs Nigel, I'll take some pics of what my issue is tomorrow

Here are some photos of the grease (oil) nipples showing the reason why I need 1/4" angle drive in ones.

This photo below is of the front of the saddle just below the crossslide handle:

This one is of the top front of the saddle nearest the tailstock, difficult to photo but there are 2 here:

And the last is of the top back of the saddle and is the hole furthest in:

I don't want to drill out and thread for the next size up as I don't want to risk getting cast iron swarf into the oil ways.
