About 2 years ago i had a Cheddar Pintail that i was having problems with. I took it to John Hemmans who quickly identified and corrected a gas tank problem and the plant worked perfectly thereafter. Visiting John's workshop was amazing. I spied his magnificent steam plants and vowed to aquire such a quality item before I retire.
Recently I obtained a hemmens steam engine and boiler although not originally purchased as a matched set and without a boiler certificate.
I took the box along to John and asked him to check and certify the boiler, replace / service the unit and fit it onto a plate unit ready to fit into a hull.
Today i picked it up and it was amazing. Looked as good as new. John fired it up and briefed me on how to operate the plant and provided spanners,steam oil ,fill up syringe and instructions including a brand new certificate.
Excellent job John.

Very nice. How much does the whole unit weigh?

gyronuts · « **Reply #2 on:** August 11, 2010, 07:13:56 pm »

sorry I have been away on business. Will try and get it weighed by the weekend. Do you want the weight with or without the gas tak? Bill

All inclusive, please, to know how big the hull needs to be.

Hi,
Will do. I am fitting it into a Krick Victoria. I have removed the superstructure and it seems to fit fine. Shortening the propshaft as well. The krick is 1077 x253 or 43" x 10.12". . More pictures tomorrow.
If you look at John's website www.steamengines.co.uk you will see that his hulls for the plant are 43 to 47" long.

superstructure removed and steam plant in temporary position to check balance of boat.
Boat as seen with plant + gas tank weighs 5Kg. The smaller launch is 38” long, by 12” wide and weighs about 3kg.

I know the union jack is upside down!

The plant looks very nice in the hull. What are you planning to do about the old cabin? I would scratch build a new one, as I never liked the standard Victoria cabin.

Thanks for the data!

gyronuts · « **Reply #10 on:** August 14, 2010, 07:34:57 pm »

I am going to lave the hul primarily as it is rather tan build a new cabin. But we shall see.
I have replaced the propshaft and set it up to a greater angle from the hull than the original.

Well sailed the victoria today. What a wonderful sight. The steam plant operated faultlessly and was like a sewing machine with control over the RPM so fine that you could go from the pistons moving slowly in forward motion to the same in reverse seamlessly.
Miraculously, the propshaft and connectors appear to be in line as if an engineer had built it!!!
Now that I am happy with the setup I will remove the plant( 4 screws) and do up the interior of the launch.
Sailed about for nearly 20 + mins on about 2/3rds boiler capacity.
I have some video but not sure how to download it..any ideas?

I will see if I can take a better one. Bill

Works very well and looks very good on the water, congratulations.

gyronuts · « **Reply #16 on:** August 20, 2010, 12:17:21 pm »

I took some better video today so will post it later. General discussion amongst club members is whether to reinstate the cabin behind the boiler. Any thoughts? Bill

Bunkerbarge · « **Reply #17 on:** August 20, 2010, 12:33:22 pm »

Not for me. I have an old Victoria and have had a play with a couple of steam plants but not really been happy enough yet. I've now seen two though with the cabins removed and they look so much better and make an excellent work boat. I would keep the bench seats and put in a steering wheel somewhere, just like a Borkum, but leave it at that.

I would vote for a cabin. But not the old one and not in the same place.
Actually I would like a cabin in the back, leaving the engine free, and a cabin in the front, with the steering post behind it

Here's a couple photos of a Victoria I've been currently building without the cabin.
