Hi,

Anyone has a good or bad experience with an "Andreas" engine?

http://www.hielscher-dampfmodelle.de/cms/index.php?page=shop.product_details&flypage=shop.flypage&product_id=1&category_id=81&manufacturer_id=0&option=com_virtuemart&Itemid=38

I need a very light engine and very light boiler to power the "Medea", if possible...

Feedback welcome.

Thanks

Gilles

Giles, I have no experience with the engine but it does look interesting and the price is reasonable. I like the paddler version too.  I was intrigued by your mention of Medea. Are you planning to build a steam powered version of the Deans Marine Kit? Is that 870mm long from memory? I looked at the kit when I first read about it but decided it would be too difficult to steam power it so I bought a hull from Kingston Mouldings which he had modified to build a similar type of steam yacht. It is 1070mm long. If you go to his newsletter page http://www.kingstonmouldings.com/newsletter.htm and scroll down you will see a photo. I also bought two books about Medea from the San Diego Maritime Museum which have some useful photos and drawings. I have not yet found plans for her but will keep looking. I just need to find plans of the superstructure. I have powered mine with an SVS double acting twin oscillator and a 6" x 3" (150 x 75mm) boiler. I have had the engine running but have not yet tried it out in the water. I did try a floatation test before I fitted eveything in to the hull and it looks like I will need about 3kg of ballast. I will take some photos of mine when I try it out and look forward to seeing photos of yours. Best of luck with your build. Regards, Ian.

Salut Gilles
I don't have a Hielscher Engine but saw once an exemple running at an exhibition. They seem to provide a very good value for money. Last but not least: Hielscher has a 40-year history with good reputation.

Hi Ian,

Yes that's the plan.  I was interrested by the Peter Boele but Medea was nicer. I thought Medea was same size as Peter Boele, I realized later it was only 12 cm wide  , which is not much. The most difficult is to find everything lighter (boiler + engine + gas tank...etc) as the total weight should not exceed 1,75 kg, the hull is already 290gr empty...

 ... I though a Saphir engine from Anton could fit in the norrow hull, but with the boiler it's already more than 1 kg. The big "?" is the weight of all the cabines etc, I'm going to make these in wood, lighter than the plastic parts in the kit. If I find a reliable engine much lighter I should be able to gain weight and have the hull within its water line.

The Andreas is only 40gr and the Hielscher horizontal boiler is 116 gr + 30gr (water), with that set I gain 880 gr. But the boiler is a very small capacity, so I might order another boiler in between the Anton and the Hielscher in term of capacity.

I carry-on searching for the most suitable configuration.

Thanks for your input Kaspar !

so I might order another boiler in between the Anton and the Hielscher in term of capacity.

Maybe this would be an option. Unfortunately it's only available in vertical configuration, so it might be of no use for your purposes. In a German Forum was kind of a review of this boiler and it says that quality of the boiler is good, but the ceramic-burner rather not. It is also available with fuel paste (or pellet) burner  which I guess will be lighter.
Cheers

Do you know the Kassner engines? They say that  are made for boats up to 75 cm....
