THE TROUBLE WITH MECHANICAL LUBRICATORS

- The Trouble With Mechanical Lubricators. In my opinion, commercial Mechanical Cylinder Lubricators are not as good as they once were. This example on my Simplex Locomotive does not work properly. I show how I replaced the defective parts and made a slight addition to the components.

1:07 Yes I absolutely did immediately see the resemblance! I recently watched your Blackgates Twin series, and Mr Pete's wobblers and now I understand a bit of how simple valving works in these things.
The cylinder is mounted on a check valve which puts the it way up in the air. It's supported in another dimension by the threaded rod. It's that third dimension that needs more support. The nut on the threaded rod helped. A large washer under that nut would help, and review other options at the check valve mount point.
'They work most of the time.' Except for when they fail and can destroy something major. Excellent series, I'm learning a lot.
Interesting fix. Glad you managed to get a Girl Friend joke in.
I didn't realize just how small this component was until I saw you putting that brass washer on the shaft!
Very informative video. Our engines lubricator has just stopped working after 31 years with no problems. Not too bad if it’s another 31 years before it goes wrong again
Fine fettling.
I’m new to model engineering and I was wondering why you would use a mechanical oiler rather than a displacement oiler or a drip oiler.
Because they are better and more reliable - like on the full size.
Keith - I had water in my cylinder lubricator today.. It had little bubble forming which leads me to believe the check valve wasn’t working and steam and or water was able to get inside. I cleaned it out and she seems to be pumping now. Anything else I should check? If she has condensation and or a bit of water in her before I started do you think that effected it? I did move her up and down the line to prime the axle pump and I fear that’s when water got into her. Thoughts?
I always use 2 check valves. The one on the lubricator plus a second once on the cylinder(s) feed
@@keithappleton Thank you for getting back to me. I believe there’s a second set in between the line going to the cylinders. I’ll check those out.
Hey short question
I have a small "Ruby 1" Accucraft modell, but it doesn't come with a watergauge. Since I have my home in Austria near Vienna I wanted to ask if you know a company near that could fit me two fittings in my boiler so I could install one?
Sorry I don't know anyone who would undertake that job.
Grandpa joke for the day...

Thanks for making the videos

A stupid beginner’s question. You stress time and again that constant lubrication is all important. When explaining the new lubricator you say it draws in steam oil on the upstroke and pumps oil into the system against the check valve on the downstroke. That said, the oil is pumped in only each half turn, that is about every twenty (give or take) engine turns, depending on the fineness of the lubricator’s ratchet, and then engine runs “dry” for another 20 turns.. Is that still sufficient then?
More than sufficient. Most Mechanical Lubricators supply too much oil . . .
Keith, did you ever manage to sell your "Ken" locomotive that you ran at your other house.
Yes I did. It was bought by a man who currently needs to sell it to fund some property repairs. He is asking £4,400 if you are interested.
