Today I got close, but not quite... the left valve isn't sealing, so the air's going straight out the exhaust. I'll pull it apart later and have a look, I suspect the valve's just tight on its drive bar and needs relieving a bit though.  Anyway, cooking a roast for dinner, so I'll look into it another time. |

Hi Lisa,
Yes, that's usually the case.....Just bear in mind that the valve must be free enough so that it can move away from the block by anything up to 1/16" or more depending on the individual design.........This allows any condensate to be blown clear.
I also must go for Dinner otherwise I'LL get Roasted !!

Good news Lisa!
I was reading a book last night that had about 3 pages of what to do on the full size if a valve is blowing through. I skimmed through that looking for the bit on what to do about a wheel loose on its axle only to find there was one paragraph that said 'do the same as for a broken axle'.
Anyway, I'm sure it will be a easier for you to sort it out than in full size.

She's lumpy, there's one noticeably weak stroke, and fair bit of pressure is needed to get going, but the chassis is running on air as of this afternoon.

Brilliant! It's so pleasing to see a chassis come to life like that, all that effort is finally bearing fruit.
Have a great Christmas Lisa!

Great job Lisa, well done! It may smooth out a bit with more running / bit more air pressure. Use plenty of oil on all wearing surfaces during these first runs. It's a great achievement to get this far with a locomotive.

Good on you Lisa. It will most likely get better with some more running in. Make sure that you use pleanty of oil as the air usually contains a lot of water that condenses in the cylinders.

She's literally dripping in oil in places (don't have to worry about oily rails yet!), and I unscrew the blanking cap on the lubricator connection and put a squirt of oil in before a run. But everything's freeing up more and more as it all gets a good run in; so less pressure is needed and she's not quite so lumpy.

A big step forward Lisa... well done to you, you can be rightly proud of reaching this stage....
Kind regards

Well done Lisa. I think the first time you watch the wheels go around on air is almost as good as the first time you open the regulator on the track!! I'll be watching!
