Parting Off Drip Oiler With Plans

[jjr2001]

Simple project made from .875 brass stock and some brass tubing.

This project was made after inspiration from Marv's Parting Off Oiler.

I already had a magnetic stand for a large dial indicator that I was not using and that
meant that I had my oiler system half done before I started turning the brass.

I used a 3/4-16 tap and die for the threads on the reservoir and the cap.
The threads were lapped with fine valve grinding compound to allow the cap to close completely.

I also use a thick oil (STP or Lucas assembly lube) on the cap threads
which help to seal the threads for low pressure.

1/8 brass for the main tube and 3/32 for the "nozzle".
These were soldered together and into the oiler.

An 8-32 thumb screw is used for a plug in the "air vent" in the cap. This was done
to provide a slight pressure when the cap was installed to increase the drip rate.
It will also reduce the rate if slightly rotated so as to remove it. The cap is not
an absolute requirement but it is nice to be able to increase the flow of oil
independent of the 10-32 "switch". Also keeps swarf out of the reservoir.

The 10-32 thumb screw is just an on/off switch.
This screw has the end modified to a conical shape which allows
it to stop the flow of oil if no pressure is applied with the cap.
