Yep,
very nice. I am frequently browsing through this really interesting forum. Obviously in Germany our hobby is in many cases carried forward by young mechanical engineering students trying out their ideas. Unfortunately no drawings for this nice little pump

Yes, Florian will post the drawing when he has finished them - he obviously worked the other way around :D I'm hopeful about the plans, because I hope he is incouraged by all the interest :)

Is that a steam powered water pump? I have toyed with the idea of building a steam powered water pump to look like an air compressor. This looks pretty close, but the big square valve boxes would have to go.

Hi,
the builder of the tiny steam operated water pump got in touch with me. He considers building/selling a mini series if he gets 5+ orders. If you are interested, please send me a PM, I'll forward it to him. I am in no way connected to him, I just act as human mail server...
A video clip of the pump mounted on a loco can be seen here:

Is there a photo someplace that would show the size of this pump? I can tell from the photos on that site that it is "small" but I really cannot tell just how small. Is it appropriate only for something in the 1:20 scale or larger or could it be even smaller? I AM interested, but not sure at what price my interest might wander off.

Henner:

Could you ask him the price assuming he gets orders for 5? What price if he got orders for 10+?

Very interesting ... I've been relegated to thinking much smaller lately (pondering bit and pieces)
and re-reading Yoder and Wharen's "Locomotive Valves and Valve Gears". Making something
like this is more within my time/labor constraints....

I have to say I found the google translation of the first post fascinating:

From: http://translate.google.com/transla...iewtopic.php?t=7545&hl=en&ie=UTF8&sl=de&tl=en

"The following figures show the final stage of the disease. Anfälle von Konstruktionswut und
Verkleinerungssucht begleiten die Krankheit und führen zu immer neuen Ideen und Lösungen.
Konstruktionswut and seizures of narcotic reduction accompany the disease and lead to new
ideas and solutions."

Yep ... live steam widgets like this are definitely a contagious disease leading to new ideas.

The size of the pump:
Height 47mm not counting the screw heads (49.5mm incl. screw heads)
Diameter 15mm.

I just feel I "must have" one of these! :-D

I don't think the demand will be less than 10 pieces... but would it really be enjoyable to make any more than 5-10 pieces?!? Also, unless the builder uses CNC operated machinery, and does a much longer production run (100 pieces or more), I guess there will be no discernable decrease in production cost.

When this discussion started at the buntbahn forum, I mailed Mr Regner, suggesting he pick up production of a steam waterpump. However, he doesen't like writing mails, so I guess I will call him up and ask what he thinks of the idea. He's more of an action man, so so I would not be surprised if he allready is constructing a steam water pump ;-)

As to cost, in my view / guess, the pump is technically comparable to Regners smallest twin ossilating ship machines, with a list prices of Euro 200 (=USD 315). One may have to add the cost of a lubricator, adding between 12 to 40 Euros (=18-65 USD).

Although I will presumably not be a cheap accessory, I still think it would add enough operating fun to justify the cost! After all, you would now operate a second steam engine at the same time, so that ought to give twice the fun?!?! :-D
