Why don't we make models of things like this?

I have gathered quite a lot of information on steam hammers, one day...

Same reason that stone-aged technology V-twin motorcycles outsell the latest hi-tech four cylinder jobbies. One just sits there and very efficiently spins away flawlessly while the other one goes chuffa chuffa chuffa and jumps up and down. Something to do with resonating with the human heartbeat, taking us back to the womb etc etc. So I'm told...

I have a fair interest in this sort of thing:

One of the stoppers ( ? ) is the difficulty of getting Silicon Iron laminations or Soft Iron.

Tried some years ago but got nowhere.

One educational supplies site actually listed 3/8" soft iron rods but were actually mild steel when quizzed.

Unless someone knows where the stuff can be obtained in smallish quantities.

Hi Dave

About 25 years ago I bought some soft iron from my local transformer winding company approx. 1mm thick 60mm wide another sauce is old welding sets or spot welders.

Hope this helps Paul

Neil as far as I know they are casting kits so you machine the metal though I'm not sure if you have to wind your own 'lecy bits or they come ready wound.

TS also do a steam saw which would go well with your hammer

I've heard the suggestion that steam engines remind us of an earlier stage in the process...

I would be tempted, except I've just had to pay my half for the four leylandii on our frontage to disappear. I've cut down smaller ones in the past, but the biggest one has left a stump about 20" across. The growth rings showed it was putting on 1" of diameter a year over the last ten years! I could have taken it put with a bowsaw when me moved in - I did actually get rid of four or five that way when we moved in in '02.

Maybe stick with something a bit simpler for now, this is a nice little generating plant complete with burner, boiler, engine and generator

Hopper I think this could go into a whole thread on its own there are many reasons for the different engine layouts, horse power and torque being just two of them, yes a strait 4 is somewhere near smooth, but then you have a V4 layout which is smoother again in a smaller area, and if you get into the advanced engines (not availible to the public) where you have a ignition every 180 degrees it becomes smoother gain. where as with a V twin engine, it is designed to give higher torque at low rpm, which is why the likes of Harley need them to pull along their tractors, oh sorry motorcycles

It's not only the Germans that like them, couple of examples from the US

For the workshop or just as the perfect way to crack a breakfast egg?

Some generatorsets made in the Netherlands.

I'll stick my head above the parapet here! I think that small generators have to go really fast to generate any sensible output. I seem to remember that Tubal Cain (TDWalshaw) many years ago described a model Gramme ring generator in ME, he later admitted that he never got any output from it.

Having said that, some of the models shown in previous posts are really nice to look at.

If Google translate is working correctly those kits are casting sets inside which you can fit a motor to act as a generator.

I would like to build a model of a Alldays & Onions steam / air hammer someday if i could find drawings of it,in the meantime keeping myself busy with a Hunslet in 5in.

So, basically playing dress-up with a motor? I thought the idea was you built the whole thing.

Where's the fun in that?

Excellent Johan, thank you for sharing those pictures.

Neil

How about this (1/1 scale) set that I saw on a visit to Crich Tramway Musem in 2014? 

Unfortunately the Brush gear was not on there..

I have put some more images in my album.

I seem to remember seeing a nice Generator Kit in the Cotswold Heritage adverts.

Stuart Models also make a Generator kit.

It's a megger!.... grasp the two handles s-s attached to the binding screws of the dynamo, your pal winds the pulley & wallop you get quite a few volts through your proverbials, providing it's way less than 30 milli amps  .Got caught with that one when serving my apprenticeship.

We use a Canning generator ex an electroplating shop similar to this one on the water turbine at our museum. It's 12" to the foot scale, so 6 volts at 600 amps is what the specs plate says, we run it into a couple of 12V incandescent light bulbs.

the turbine it's self would make a good model, I have built a fairly rough model that we use on site to explain the working of the full size turbine.
