    Has anyone built a model of the c1910 gyro stabilised mono-rail car?

    Was reading through a 1985 modelling book which is a reprint of 1925 Model Making by R.F.Yates and came across plans for modelling a gyro stabilised mono-rail which had pictures of a model balanced on a taught wire, as if by magic. The design had a single vertical axis gyro doing the job, but...

    Stuart Turner Wikipedia entry

    Have updated the Wikipedia entry for Stuart Turner to something much more substantial using all the sources I could put my hands on (it really was minimal before). It is still far from complete - and undoubtedly has errors too, but I thought it needed doing. Would love to have some extra...

    Help Identifying v Small Lathe

    This new acquisition is a type of lathe I don't recognise, and I would appreciate any help identifying it. It is only 2.5" centre height and 9" between centres, but has taper cast iron nose bearing, ball thrust bearing, felt wipers on the saddle, and hand scraping still visible on the bed, so it...

    Cutting a worm for changewheel dividing

    I want to make a worm drive to add to a simple dividing attachment that uses a changewheel and plunger on the end of a spindle. Ideally I would like this to work for a range of changewheel sizes. I assume the worm should be angled at the helix angle, but I am struggling to work out exactly what...

    Removing snapped stud from small split dies

    I now have two split BA dies in which I have managed to snap off short stubs of thread, which do not protrude, one brass another steel. These are both good quality dies so I want to extract the stubs. One is 6BA, another 8BA. I was wondering if I can sneak a slitting saw in through the split in...

    Small nuts and fat fingers

    I thought I was being smart making a small stop valve for my little steam engine and using flanged steam pipe couplings. But actually getting the nuts on the 12BA bolts for the flanges is proving more challenging than I thought (they are 'small-head' bolts too). I wonder if anyone has any tips...

    Help identifying table engine

    I know you guys love a challenge, and I have just acquired a model engine, which I think is called a table engine and would be delighted if anyone can recognise the type, design, or any other details. It is rather unusual in having a round steam chest (I haven't had the cover off yet). The...

    Problems drilling phosphor bronze

    I bought some phosphor bronze rod the other day to make some tiny bearing bushes for the engine I am building - it is quite copper coloured, and different from what I have used before which might be aluminium bronze. I am drilling to 3mm and reaming to 1/8" with a D type reamer. Both are...

    Anyone know what model engine this is ?

    Just bought this, have seen one before, and suspect it is kit built. I am trying to find out where the design came from, was there a kit, and its age (thought to be 1960s or 70s). In case the picture isn't clear, its a single cylinder, single acting, poppet valve steam engine. Inlet nearest...

    Robinson Hot-Air Engine Model x2

    Have done a quick search here and have not found any reference to making models of the Robinson Hot-Air engine (Polly models do castings). I have only built an ST oscillating V-twin, and I am in the middle of building a Stothert & Pitt beam engine - so I am a newbie compared to some of the...

    Model Spark Plugs

    I have a couple of IC models - (Westbury designs) that are part completed. They say to drill and tap 1/4" by 32tpi for spark plugs. Are these available ? One of them is already tapped with this thread but the previous owner didn't make a very good job of it - so I am wondering if there is a next...
