I think it would be easier to have mains air pressure than steam. I am reminded of the London Hydraulic Power Company that provided high pressure water for operating machinery before electric mains. There were several pump houses with big steam engines powering the high pressure mains (low...

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...

I wish we could find the original on which these are based. I have so far failed to find anything. Jonpalt posted that CME marketed a Jowitt Major, and I would say this has to be one of them and not a one-off. If someone made a one-off model based on the original Jowitt engine, whether made in...

Returning to this old thread after a long time .. Is this the same model engine in Sweden that we were looking at for auction some years ago ? http://auktionsverket.se/auction/nautica/2010-03-16/7107-angmaskinsmodell/ In which case it is indeed the CME kit, as the cylinder cover bears the CME...

Only dimensions I have are : Height 22 inches Flywheel 10 inches Weight approx 120 pounds Serial numbers were 1 (Jan 1934) to 247 (Jul 1962). Looking at the images on the web there seem to be several variations in the housing opposite the flywheel, probably reflecting the variety of uses. One...

Yes, editing is a bit messy, and there is so much I don't know about formatting yet, but at least the page was there in the first place so all I had to do was add material. However there are a surprising number of things slipping beyond peoples recall, and as a lot of model engineers start off...

Thanks Jason, I wasn't sure if S type was its correct designation, or whether that was due to the S for Stuart on the steam cover. I thought it was part of the wartime development and briefly mentioned it in that section, but now I have a list of engine numbers I can see 247 were made from 1934...

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...

With the history your fine model is surely worthy of being in a museum. Regarding the condenser, it is tricky if the bits have gone missing - K Harris has a chapter on modelling condensers and air pumps in his book "Model stationary and marine steam engines" - his air pump drawing on p101 could...

Interesting, my mistake and apologies, I have seen boiler feed pump and water pump located there, but never an air pump. Is the condenser all located in a pit below the air pump (which presumably would also pump out the condensed water) ? Maybe that could explain the checkerplate access. I...

What air pump ? Surely this is an engine used for pumping water, like so many of this type - there is no power take off that I can see for driving other machinery, so if the pump on the base is to do with a condenser then I don't see what the engine's purpose is. I was curious to see the...

Ally water pump sounds a lot better than brass, cos any combination of Al and Cu-based alloy in electrical contact together with water forms a very good battery. Anodising sure helps, as do the inhibitors in modern anti-freeze, but the tiniest defect and you risk your ally bits becoming a...

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...

Thanks, that sounds like a good investment. I'll get a copy. Steve

Thanks, a least a couple of understandable replies. I have no idea what goldstar is going on about. Maybe someone else can decode his posts. I thought making a worm and holding it in register would be easier and more accurate than using a banjo to mount two gears, as changewheels tend to be...

I have no idea what you mean. 62.5 is half of 125, 62*5 is 310. The index collars are for 8tpi cross-slide and top-slide, the leadscrew is 4tpi. The diameter has to be right, so I though to make my own. I do have lathes with 8tpi leadscrew and finer down to a Unimat, but I don't have indexing...

No club or library here - do the publishers offer these mags on line ? Worth a quid or two to access the right article when you need it. Well I am keeping an eye out for a cheap dividing head, but if worm and wheel is easy enough I could apply the same approach on my IXL lathe, which also has...

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...

Thats entertaining, though when I google for Almond Drive all I get is a lot of addresses. I can see that being an entertaining way to drive valve gear off a crankshaft instead of bevels, though the oscillating mass in the middle presumably limits it to low speed.

Interesting thought - that would be something like a Coronet wood lathe, they have twin bar beds with the headstock just clamped to the bars, and a simple woodturners tool rest. The use of bars in place of a precision ground bed is a way to get a lathe bed at modest cost, though probably not...
