Title: Small dynamo for sale on ebay - any info on what it is ?
Post by: Gas_mantle on April 16, 2018, 10:45:51 PM
I came across this that I may be interested in :-

https://www.ebay.co.uk/itm/6-volt-Dynamo-for-live-steam-engines-much-larger-than-the-Stuart-Turner-dynamo/323208091939?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2055119.m1438.l2649

Does anyone here know what it might be etc ?

It looks fairly hefty compared to the Stuart, I asked the seller and he says it gives out 6v at 350 rpm but doesn't know anything more about it.

I thought it looks about the size to go with a replica Stuart no4 I'm about to start building, I have no specific use in mind other than something for my engine to drive but I'd be curious to know what sort of power it may deliver  :)

Cheers
Peter.

Hello Peter,
It looks like a dynamo made up using aluminium castings that I used to see for sale at model engineering shows. I made one up using the fan motor from a Ford Sierra. Driven fast enough mine will produce 12 volts.

Hi Graham, yes please.
Reckon it's worth having a go with one of these armatures being offered on eBay http://www.ebay.co.uk/itm/130824-12-VOLT-12V-22-AMP-LUCAS-C40-DYNAMO-ARMATURE-UW100-UWB102-227271-26212754-/281815295225?hash=item419d8024f9:g:-GYAAOSwj85YL0Hf
These folk in Solihull have a range of armatures for C40 dynamos, can you recall whether a specific armature was required?

I only saw the 'Manchester' dynamo castings when my late friend Ted bought a set when we called at Tuttle Street in Wrexham to buy my RLE castings from you. That may be 20 years ago, I vaguely remember a rectangular base, perhaps two bearing caps and I think there were plans.

This afternoon I remembered that I made up a dynamo using the heater motor from a Ford Sierra and 3 aluminium castings bought at a model engineering show in Wembley. The Sierra motor is quite capable of producing over twelve volts when driven by a cordless drill. I had intended to drive it with my model Gardner 0 type but the engine didn't take to it.
I attach some pictures of it, Naturally  I did get a much higher voltage driving the dynamo belted up to the flywheel but it made the engine difficult to start.

Here's a video of my Gardner 0 Type driving the dynamo at a very low speed..

Thanks Andy, it hadn't occurred to me that it could be a home made item.

I like the retro look of these kind of dynamos, the one you made looks great.  :)

To me the Stuart kit to make one seems too pricey at nearly 200 after VAT and the PM Research version looks a bit small so this one seemed to fit the bill.
