Drill Clogging

[nat_wheatley]

I recently added an inline oiler to one of my drills. For some reason it's causing the drill to bog down/clog. The drill runs fine at first, then gradually is losing power. (one the cleaned out, it runs fine). Not sure if its the oil I'm using, or perhaps the dosage.

The oil is a pneumatic tool oil from HD. I've run the air full bore through the oiler and it doesn't appear to be adding too much oil, but it may be that it is.

In the past I've added oil manually, with no issues.

It's probably the cold. Cold = higher viscosity. Maybe substitute WD40 until it warms up a bit.

On a side note, it wouldn't be terribly difficult to swap out the pneumatic one for an electric one...It never made sense to me running an air drill that requires a good 7-10hp of air just to drill some holes. Even the best HF drill is cheap enough to hack apart and mount on the air drill chassis. Then hack the code to turn on the drill rather than the air drill.

Thanks Brady. Temp is OK in here (60deg), it must be that I'm flooding the drill with oil.

Oiler is off the machine right now, but when I have time again, I'm going to put it back on and run some test drilling...

May have solved this problem FWIW. Originally, I ran the drill full bore to set the dosing, watching how often it added a drop. Today, as I was trying the oiler again, I noticed that it adds way more oil if the drill is turned of an on and off (as it is between each hole that's drilled), than if it's just getting a steady stream of air. Fairly sure the drill was just getting flooded with the oil...
