drip oilers

[dallen]

I was asked to start a build thread on the drip oilers that I need for my shaper,

I borrowed one from a friend so this is more of a backwards engineering project then anything else. I'm not trying to reproduce ones like the borrowed one I just need a couple that will drip oil to lube the ram on the shaper when its running.

first up is a photo of the one that I borrowed that I have partially disassembled, thing looks like it was buried in the ground, its pretty dirty. you can also see one of the metering tubes that I have made



second photo if of the metering tube and the part that the sight glass fits into the turned end will be threaded 1/4" NTP.



This photo shows some bronze rods that I casted as I don't have any brass round stock, in the photo you see the valve rod from the borrowed oiler this is probably the most complicated part in the whole oiler. threaded up some 5/32 drill rod to make the needles out of.

Great project, love the old machines with these oilers.
I just finished resurecting a very old shop built bandsaw, flat belt driven and lubed with the oilers. I have geared it down to cut sheet metal, (body metal thickness.)

I know what you mean about old iron, I played with the shaper for a couple hours today since I have it running on OG&E now.

but I did get in a little bit of work on the oilers also

the first photo is of the bronze rods that I poured yesterday, I borrowed a slitting saw and after turning one of them round I cut a slot in two pieces to use to make the little lifter handle for the valve rods.



The second if of the second piece that I need for the sight glass, I made one last night and put a round viewing hole in it. The original has an oblong hole, as you can see from the one on the left in the photo I screwed up the one i did tonight, anyway I'm going to use it for now.

here's some more info on how I made the knobs

in my last post I showed two pieces of brass with slots cut in them. After some trial and error, more error then trial I figured out that I needed to solder in a filler so I could turn the parts without them bending. They also have to have a hole drilled in them so why not do it when you cut the slot that way they are square to one another.

Heres a shot of one before soldering the filler in place.


second is of one in the lather being turned to final diameter.


and the third is of them almost finished one still has to have the hole drilled and the fillers removed


there not exact twins but whos going to be looking that close at them.

Ok I haven't forgotten about this just put it on simmer for a couple days.

After some looking and such I've decided that I want the bodies too be 2" OD X 2" high, one reason I think that size will look ok on the shaper the 1.5 X 1.5 I feel will be too small. So now I just have to figure out enough stuff that I don't really need but think I can't live without to make up the minimum charge from the outfit that has the glass.

Till then I still have three more of the endcaps for the glass too make up. Here's a shot of one I did this morning out of a hunk of A36 plate, stuff turns like crap, or maybe its just my skills that are lacking, anyway I got one decent looking part out of the mess.


Also figured out that the holes of the oilers on the shaper are threaded 1/2 X 20 TPI so I threaded them also not my prettiest work but the jam nut spins on without any wobble.

And I also threaded up some springs stops for a better name, that go on the valve rods to put tension on the springs, their 8X32 Thread and just under .250 OD so that they will slide down in the stems. Which I get to remake as these are too short for the 2X2 glass tubes I want to use.

Sorry no photo of the Nuts.

got a bit more done on the oilers that I've been working on.

first photo is of the form tool that i ground out of a hunk of T15 tool steel to cut the inside radius on the end of the stem tubes, the end of the tube has to be about 1/8" in diameter from measuring the original one that I have as a pattern.



second photo is of the two new stem tubes along with the bottom's that the glass tube sits in. the ends will be silver soldered to the stems, I am at the point that I need to glass bodies now so I can do the final cuts to fit the cups to the glass tubes.

Nice job on the form tool David.

it should of been flat on top with no rake, but the bit was one that I had already used for something else and the side I turned up only had a slight negitive rake on it. It actually cut pretty good, I had it on center and would crank the cross slide in about 10 15 thousands and then run the carriage into the part to the depth that I needed, using lots of dark cutting oil.

Dave, I've reached the point of needing the glass tube's, or I may just use some stainless steel tubing I have so I can call them done till I get the glass. They have actually been a lot easier to make then I had first thought they would be.

The one part that I haven't really figured out is the little cover over the filler hole as its spring loaded I may just put in a tube with a drop cap on it and a little chain or something to keep them from getting misplaced.
