" Elsa ", is a steam dredge barge built by Buxton Model Boat Club member Dean Ratcliffe.
She is roughly 1.24 scale, approximately 43 inches by 8 inches and is made from recycled and up cycled materials wherever possible. She has a single rudder and propeller, powered by a single motor from a drill, and two 6v lead acid batteries. She is a totally freelance design.
Think I've finally sorted the mixing smoke and water for exhausts problem. Graham has already done his using the same pen / e-cig unit but with some nice electronic controls for the on off system, but not having the electronic abilities I've just gone with a more basic method. Wired up the pen and installed a filler tube (2 tubes are better - one for a breather) these are capped after filling to prevent air getting back from the pump. This system has a water pump, an air pump and the smoke unit, (all adjustable with their own voltage buck) Thanks to Martin for his pen suggestion. I was previously using large capacity elements fitted in various containers for my experiments (truckloads of smoke available) but these pens are great for tight spaces and don't draw much current.
Air, and a small amount of the cooling water are mixed by venturis just short of the exits (the air pushing the smoke and blowing the water clear of the smoke tubes). I've fitted the same system into my ST but am still waiting for the air pump from China (postal system problem there, then Chinese new year holidays with new rules apparently) Get the odd bubble at rest but with the low exhaust you can't have everything.
Latest vid with boat in the tank.
Thanks Peter, took a while to get there, should see the pile of stuff I've collected while doing all this experimenting! Have a smoker for every occasion😁!

You're getting around a bit arencha Ron 👍
Tug looks kinda Springerish.
A pusher tug for barges or logs?
😎
Turns out she's a 'Puller' 😉 A 'Pushmepullu' 😁 http://www.tugboatinformation.com/tug.cfm?id=3524

Here's a short video to show some of the varied and interesting exhibits and features seen at the London Model Engineering Exhibition, Alexandra Palace 17th - 19th January 2020.
Enjoy....😀

Glad you like the video Mike.
As you know from your visit to the show last year there's a lot to see and my video only covers a fraction of it but I think it gives a good flavour of the whole show. My brothers Meccano Missouri was a big hit with the public too, he will be showing it again at one of the Warwick model shows later in the year.

She is back in dry dock for more fitting out by Lee who constructed and owns the model.
She is quite a beast at 1/72 scale about 6ft / 2mtr long. Fleetscale kit/parts i think ?.
Special significance for me that my son has served on HMS Iron Duke.
Hi Phil,
Wonder if your son was on board when I had a look round Iron Duke during the Exponaval in Valparaiso naval harbour many years ago?
When not at the exhibition discussing the COMMS fit for the OPVs Armada de Chile have since built I was on the other side of the dock doing some upgrades to a 1kW HF transmitter on a Leander frigate. Took longer than expected to upgrade the SW so I nearly ended up sailing with her. Might have been fun😉
Cheers, Doug 😎
Just for fun ! an interesting project for the new year ! - RC Sailing :- Mississippi Steam Boat from BMBC member - electric conversion with original steam / boiler setup .
Happy 2020 to all !!
Remindes me of berthing alongside just down from the Crescent city connection bridge, near Canal Street - I`m sure the "Precedent" steamer used to be there 45 years ago ?.
I like your paddlewheel “Mark Twain”!
The boats namesake is quite a prolific writer, and in his book “A Connecticut Yankee in King Arthur’s Court” he talks about his time in England. I don’t know if you smoke cigars, but an interesting paper he wrote is more about the nature of people, “Concerning Tobacco”....this is a short paper. Funny, but oh so true!
I like the Calliope!
Crew posting to Tug, still in dry dock and more crew to be completed and fixed to deck, limited room, but at least 2 more to go......still to be maidened, happy with subtle weathering....not over the top...fender soaked in some tea bags for a week....satisfactory end result...
JBRC, thanks for the compliment, figures sourced from Shapeways, just search online, Merchant Navy set No3, any scale can be achieved, within reason....I've been really happy with them so far...
Gave up trying to fit a smoke device in the HSL due to lack of room so decided to try something else. Set up the twin small air pumps (1 per exit) and made some y joints to link them to the pump and exhaust outlets,. Works reasonably well and not too noisy. Breaks up the flow a bit and gives it an 'exhaust flow look'.

Hi Mike. I used 2 mini air pumps (3v) same as the one you are using, (1 per side) Drawing is of method used but without the smoke (as mentioned,- no room) and just running an extra line from the cooling pump instead to the smoke/air exit. The larger 12v pump I tried (see latest smoker attached to exhaust pipes vid) works a lot better and is quieter if you have the room.
John
Well done.
