How to get oil to the cylinder

[Michael FodenParticipant @michaelfoden39595]

This must seem like a stupid question, but how do I get oil into the cylinder of a small stationary engine,

It will not be run on steam, but the only way In is by removing a cylinder cover, & this can't be right. There are oil grooves in the piston, – does the cylinder retain the oil that is first added or does it need a top up occasionally ?

Any advice will be appreciated. I hope to run it on compressed air.

Many thanks

Mike.

If you are using compressed air, you could use an air-line oiler from Machine M**T perhaps.

If running for small amounts of time then a drop of oil into the inlet before you connect your compressor hose will sit in the valve chest and slowly work its way through the cylinder lubricating as it goes. For long runs then as SB5 says an inline oiler will also do the job

Thanks for the information -much appreciated.

I too am curious about the oil question for running extended periods on air.

Do you mean something similar to this **LINK** for an inline oiler.

Yes

Having once had a minor "seize up" running on air, (fortunately I was using silicon piston rings), I have been very cautious since. However, I did experiment with a Roscoe dead-leg lubricator when testing my latest loco on air and found that it worked quite satisfactorily with the evidence of oil reaching the pistons showing as a tell-tale ring of oil at the chimney. Roscoe lubricators are very simple and can be made as big/small as you like from a piece of brass tube. They are fitted to a "T" piece in the air line. The only fiddly bit is the requirement to drill a very small hole of the order of 0.025". A "sophisticated" Roscoe can have a needle valve as a control.

And for the lubricant **LINK**

My 1 1/2 " scale traction engine has been running steadily at about 200 rpm on compressed air for several hours in my workshop followed by 7 hours a day for 3 consecutive days at an exhibition without a lubricator using oil-soaked string for a piston ring and an infrequent spot of thin oil on the moving piston rod.

The inline oiler in the link looks to be a really sophisticated Roscoe type lubricator and surely can't be beaten as value for money. I think that I will get one for use with my workshop compressor but dimensionally is it suitable for a small engine?

I have found that when using a displacement lubricator (designed for steam) that some oil gets through even when running on air.

Or get two for less than a tenner LINK

Colloidal Graphite?

You could fit oil cups to the cylinder head covers or valve chest cover which will allow you to get oil into the cylinder before a run, the cups on my D10 are of the taper cock type.

They will also allow you to put oil into the engine after a run to help stop condensation.
