Hi I am nearing the end of rebuilding a 3" fowler showman which I brought years ago but had to strip right down and fit new steel boiler. The engine does not have a lubricator fitted so I need to get one but I do not know where it feeds to as no holes for fitting in steam chest and the plans I got from plastows don't make it very clear. It would appear to drill down through top of steam chest right down to larger cylinder? Also where is it best to fit air line in order to try it out and get timing set up?

I know they both probably basic knowledge things but I am learning as I go and making a lot of mistakes so far so any help appreciated cheers

The lubricator oil inlet should enter the slide valve cavity in the steam chest so that the slide valve is lubricated. Oil will then be carried thru with the steam to lubricate the reverser valve and then the piston rings. Oil should not enter the steam chest where it could drain back into the boiler as it will cause foaming inside of the bolier.

An air line for testing can be anywhere on the boiler. Drain plug, steam outlet, etc

thanks for that Paul I was thinking right about the air line then as was gonna connect to drain plug same place as I been using to pump water in to test for leaks, got couple minor leaks to get fixed yet though. I was wrong on my thoughts for oil feed though, so I just need to drill and tap into top cavity for oil to drip into valve?
