Oil nipples thread size ?

[hthParticipant @hth]

My Kerry AG lathe seems to be fitted mostly with 1/4" BSF zerk type nipples . Were these particular BSF lube fittings a commonly used size on British built machinery ? I think Myford used #2 BA threads .

The Kerry also has a few non zerk nipples , these look similar to zerk, but are without the round ball .

Generally Myford used BA sizes below 1/4" and Whit and/or BSF from 1/4" and above. Sorry for the slight topic drift.

1/4 or the metric equivalent 6 mm is probably one of the commoner oil / grease nipple thread sizes on the sort of thing folk like us encounter. Full range of threads used Whitworth, BSF, UNF, UNC and M6 so sorting replacements can be a pain as the short thread length make it hard to use a gauge.

Does anybody know what type of oil gun would be suitable for these nipples ?

I have a quantity of these , the thread maybe 1/8 GAS but not sure .

One of the ordinary pump oil gun nozzles should jam in and work. Thread looks tapered so possibly 1/8" BSPT or NPT depending on the thread, 55 degree 28 TPI for BSP, , 60 degree 27 TPI for NPT

Perhaps make one.

See: MEW 178 P.46. An Oiler for the Myford Lathe.

I made one, and it works well.

Alan.

hi

 

Thanks to everyone

Yes the thread is likely to be BSPT

As for making an oil gun, I purchased a grease gun and modified it as described here , this is ideal for the common ZERK nipples
