Parting-off some materials goes a lot more smoothly if the tool is continually supplied with cutting oil during the process. I don't have (nor want) a pressurized oil delivery system so I built this.
The oiler shown in the second photo is suspended directly over the cut via a laboratory type suspension. Said suspension is anchored in one of the threaded holes in the carriage that were meant to accept a taper jig. Thus the device moves with the carriage if a conventional cut, rather than a part-off is being made.
The oiler itself is made from hardware plumbing fittings and bits of scrap tubing lying around the shop. The valve is one intended for the water supply to a refrigerator ice-maker. The 'cup' which holds the oil supply is a standard copper pipe reducer.
I don't use it for every cut but it sure beats juggling a brush and tuna can of oil while trying to gently manage the crossfeed while parting-off.
