Where can I find a hand pump way oiler for a Hardings mill?

LF, are you referring to something that fits the ball oilers? I turned a piece of aluminum with a hole thru center, about 1.5" long with a raised "nub" on the end that depresses the ball, and an o-ring that fits around the nub (the nub projects above the o-ring a bit, and the o-ring sits against the stationary part of the oiler), the other end of the aluminum is sized to fit into the vinyl hose spout of a generic trigger pump oil can. That being said it's probably not necessary to "pressurize" those oilers, but it does probably work more efficiently and not make a big mess. Cheers, Charles
A picture's worth 500 words, simple but might save a few minutes of cogitation. It's helpful if the aluminum piece has some length to grab onto (not too long otherwise it's unwieldy), because you have to fiddle with it to get it perpendicular and apply some pressure to the o-ring. Cheers Charles
These work very well... "Push" Lube Pump for Zerk Base
They even produce enough pressure to blow out the places people use real grease in....
I found this one with grease.
Amazon.com: Lumax LX-1173 Navy Blue Disposable Push-Lube Grease Gun: Automotive
Can the grease be replaced with way oil? Its the same oiler as the one H&W offers.
Sure.... Just pump it all out and fill it with oil...
There's a lot of discussion and instructions here on Bijur oilers metering valves, etc. I haven't delved into them since mine seem to be working fine. If I recall, most folks recommend replacing the metering valves and flushing the system if you get into it. Also there are specs on the pumps for the volume per stroke. (I don't know anything about the jig-borer).
I dunno if those generic push lube grease "guns" will work for oil. I have a couple and they definitely will not work with oil (leaks); the one on the Bridgeport parts page specifically states that it will work with oil. McMaster has a lever-operated one, but it's pricey; I've seen somewhere others modify a standard grease gun (need a new piston with o-ring, etc) to work with oil. Cheers.
LF you're welcome. I meant the push-lube gizmos that I have will not hold oil in the reservoir without leaking (they are not the same brand as those shown here), if they don't leak they'd probably work fine for the ball-oilers. The lever-operated grease gun (for zerks) would seem very good for flushing out systems, since it provides up to 5800 psi pressure (and has an actual zerk fitting); by flushing was meant just injecting some kerosine or such into the system, whether by the pump, oiler or some other contraption. Good Luck, Cheers.
Thanks very much. This is all great information. I will probably replace those two metering valves & already have a kit with filter screen and o-ring to further upgrade performance. I hope I do not have to flush the Bridgeport oiler system; I will rebuild the pump first and see if that helps.
Hmmmm.... All the Bijur systems I've seen have meter units on ALL the lines, else all the oil goes out through the open line and little or none comes out of the others. In fact, that's the way these systems usually die, one line breaks, and then the others fill with crud because of no flow. Are you sure there isn't a meter unit at the other end of the line? Perhaps someone left one off?

Thanks, Dennis. I wondered that too. The right hand outlet that goes to the table, on the _new_ Bijur I just installed has the same size hole as the others. However, the previous unit had a smaller hole that fits the smaller fitting on the line (flex) that comes from the table., i.e. no metering valve in line. I ordered a bushing from Bijur that adapts the existing flex line to the larger hole in the unit. The tech service person said that "they made a mistake tapping a hole that large", meaning that the flex line traditionally does not have metering. Maybe the bushing I will receive Monday will have metering but I assume not. I could try clamping the table flex line on the older Bijur and open each of the other fittings one by one to see if flow increases (without flow going to the flex line). So, I will do that experiment and see. If it is the same small drip then I will try putting new parts in the unit and hope I do not have to flush the system. The flex line goes to a manifold with lots of lines attached. Thanks again for the heads-up about the need for metering all lines. LL
Assuming this is like the other ones I've seen the flex line does not have any metering, it just get oil to the manifold. The manifold then has a metering piece on each outlet. Mine is on the saddle under the left side of the table.

LF, yep, it's getting a bit too metropolisitic/suburban-sprawl around here for my tastes (I've been in the same spot for 30+ years). I'm south of Cary (the Apex came from decades ago when the mailing adreess was determined by city by the city where the mail came from). Let me know if you need to take a look at the TM or mill. (your mailbox is full), Cheers, Charles
