I hope there is someone out there who can help a very frustrated fellow live steam enthusiast!
I have a 50 year old 3.5 inch LBSC Maisie. When I first steamed her up I found that when opening the regulator all the steam went up the chimney. So I stripped down both cylinders, lapped in the valves and ran each side independently using air.Then i ran both sides together using 50lb of air, making sure that no air went up the chimney in mid-gear.

When I re-steamed her, she held steam on mid-gear for a short while but it wasn't long before all the steam went up the chimney again and the loco went nowhere.
Could anybody please advise me as to the next step I need to take. I have set myself a task to get this loco running again so that the 92year old whom I bought it from could see it running once more. Needless to say time is of the escence.

There is at least one book by LBSC which deals with a range of aspects of building and operating live steam locos; I saw it recently in a book fair at Hatfield House, but I regret I cannot recall the title. There are also more recent books by Martin Evans which might hold relevent advice.

I'm fairly sure too that most of LBSC's designs have books/booklets about them. A check with Camden Miniature Steam Services www.camdenmin.co.uk and other advertisers in 'Old Glory', 'Model Engineer' and similar mags may be of help. Also booksellers specializing in transport/railways/models may be of help.

The other possibility is to see if there is a group of model engineers about that are close to you - most counties seem to have one or more societies of 'Model and Experimental Engineers' - and seek help from them.

Thanks for the reply John. I have the book "Maisie in Words and Music " which may have been one that you saw. Unfortunately it doesn't really have a trouble-shooting section. As to going to a local club - I went down that route and found the members very clicky and unwelcomming of newcomers. I struggled to get a hello out of many of them let alone advice
. My nearest club is a round trip of nearly 40miles and as a working father of 2 - time is not something i have in abundance.
So,
I will await any further help anyone can offer. Thanks again Trev

Please reassure us that you have had the boiler tested before steaming up the loco. If not you have an potential bomb.

Good luck, I just love these locos but do not have the engineering skill to build one.

Just come across the following book in Herts Library's reserve stock: "A Manual of Steam Locomotive Restoration and Preservation" by D W Harvey. (The noted Mr Harvey who was Shedmaster at Norwich in steam days.) While aimed at the 12inch to the foot scale, it does have a section on trouble-shooting and in particular checking valve gear settings which may be adaptable to a model.

Some books you might look out for - "Model Locomotive Valve Gears" by Martin Evans, "Manual of Model Steam Locomotives" by the same author and "The Live Steam Book" by LBSC.

what an old thread, but my guess is the slide valves are a bit dry of oil and falling off the face of the cylinder. if you put it in gear and push it along with the regulator open the movement/rattling of the valves should allow them to seat back where they should be with the pressure. this happened with my winson pug. i stripped it once but realised what was going on in the valve chests. while stripped i lashed lots of oil in the valve chests to help them stick in place.
