I own and have done for a couple of years a steam launch fitted with a 10hp LIFU engine circa 1895/6. I have been happily chugging about despite my blissful ignorance of most things steam. However whilst on holiday in Pembrokshire over Christmas I was in discussion with a lifelong traction engine man who asked me what cylinder lubrication I used. When I told him that I used nothing and that as far as I knew it was not required and there was no provision, that I could see, to add lubrication to the cylinders he was dumbfounded. This strong reaction has planted a big seed of doubt in my mind. Can anyone put my mind at rest as to whether or not I should be using cylinder lubrication, and if so how to inject it, and also if used where can it go other than into the boiler via the condenser? All contributions gratefully received. Andy Griggs

Hi Andy,

Don't worry, if it wasn't fitted with one originally you probably don't need one.

If it works unsuperheated at 100psi or below you should be ok- the saturated steam lubricates the cylinder with the everpresent condensate it produces.

However, a small amount of oil would provide certain peace of mind and prolong the life of the piston rings and cylinder.

If you were to fit a lubricator, you can't go far wrong with a displacement type- this would just need a 'T' cutting into the supply pipework. Many new and second hand can be had, try Preston Steam Services as they always have loads on sale.

You would need an oil seperator before the return to the hotwell- these can be simple to make and maintain and not hard to make reliable. Many in the SBA have made them- a few designs have been published in past funnels.

Hope this helps,

Greg
