Silly little question

[Downwindtracker2]

I replaced the feed rods and nuts on my RF-45 mill/drill. It had been CNCed so it was missing parts as well as having worn out rods and nuts. . Thomas Skinner brought in Rong Fu parts for me but the parts didn't have oilers. I pulled a couple out of the remains of the old parts and ordered a pack. It being a metric machine I thought they would be 6mm. NO, they are 1/4" . I still have to order a couple.

Grease is just oil suspended in soap . It doesn't stay suspended and leaks out of the guns.

The thing to know is the pressure requirement may vary & some of the typical hand oilers fall short. When the oil passage leads to a narrow opening like the face of a dovetail ways, or side of a close fitting shaft, or a long passageway filled with mung, the required hydraulic pressure may exceed what Grandpa's drippy-do oiler can provide. That's where these injection styles enter the picture. Also way oils are more viscous but I don't think that's much of an issue compared to the dimensional constraints.

Peter, the YT link a few posts up covers this really well.

Well I just got my new ball oiler in the mail from “Myford Spares” in the UK today. Not cheap but the building quality is great!!
Part number 15472 Oil Gun

Looks suspiciously like my Reiling;

Yeah, that's where I got my 6mm ones.

Thanks for all the input! I have some oilers like those that others have mentioned, but I seem to end up with as much oil around the ball as goes down the hole.

I'm thinking of making a tip that has a a rubber collar that I could push down on the fitting so the oil has nowhere to go but down.

That, or a serrated tip so the ball can't form a seal in the opening that forces oil elsewhere.

I modified a regular grease gun and made it into an oiler. If you use a decent quality needle all the oil goes down into the oil fitting.

The Amazon and CT oilers may be the same thing but their part numbers differ:

40469-A for the Amazon one and 26365 for the Canadian Tire one.​

Further to the Myford oiler: yes, mine appears to be well made but it still leaks!

I find the my conical tapered tip works quite well when I am pumping the oil, but has soon the tip is removed I get a pressure build up spill, coming out of the ball and the tip. I have also tried to leave the tip inserted for a longer period of time, hoping the pressure would bleed out but it still make a mess but less.

From the picture, it looks like the tip is concave on the Myford oiling pump, I wonder how well that will seal on the face, but it will push the oil pass the ball without touching it.

I like your rubber collar idea Tom
