V twin double acting oscillating engine.

[Mark P.Participant @markp]

Hello all, I am looking for a set of drawings/plans for a small V twin double acting oscillating launch engine. I have trawled the internet to no avail,I seem to have gone round in ever decreasing circles. Can anyone point me in the right direction please?

There is probably a Malcolm Beak design on Paddleducks otherwise if no responses here ask on Modelboatmayhem.

Hi Mark,

The Model Engineer magazine (Jan. 2003 to Nov 2003 IIRC)ran a series of articles by Colin Pape on oscillating steam engines. One of his engines was a twin V double-acting.

You can just enter the authors name here and search for the relevant issues.

Reeves do a V twin double acting engine, unfortunately it does not always self start in forward and reverse the V is not wide enough. Mine powers a small radio controlled Victorian steam launch.

Lots of designs on the internet. Try john-Tom.com

[Mark P.Participant @markp]

Thank you for the replies, I tried John-Tom David but there was nothing suitable there. Is there anywhere where I can buy plans from have tried myhobby store.

I have the Stuart Models stationary steam engine, twin oscillator plans,they relate to the castings kit and were bought from them when they were on Guernsey.

Why not just take the design of an existing double acting single and modify it into a twin version ?

[Ian HewsonParticipant @ianhewson99641]

Blackgates do a vee twin reversible engine.

[Mark P.Participant @markp]

Hello, I have thought about that Peter and that is one option.but I would like to build a tried and tested one. I don’t want to buy a kit as I wish to build from scratch.

Can I suggest the article "starting in steam" by Peter Arnot , in Model boats magazine commencing in June 1988. Just as a matter of interest, there is also a four cylinder version with both boiler and boat design.

I am building both the two and four cylinder versions myself.

Couple here but not sure if they are double or single acting, first one could be as it says "duplextype"

Here and here

What about Brunnel's 'Double Diagonal' drawings (£23).
**LINK**

[Gas_mantle.Participant @gas_mantle]

John,

That's a useful link I haven't come across whilst looking for something to have a bash at, I'm tempted by those drawings myself but try and simplify it a bit to suit my own skill level.

Has any one built that model and able to comment on it's suitability for a beginner ?

[JasonBModerator @jasonb]

Peter, Mogens Kilde did a simplified version of a double diagonal from barstock that started in ME 4383 that would be an easier build

[JasonBModerator @jasonb]

Truck loads? only one is a double Vee which teh OP wanted and I have a feeling they are single acting

[Neil WyattModerator @neilwyatt]

They can all be made as single or double acting, I presume that the 'vee' requirement isn't absolute, as long as it's self-starting.

I can confirm the Reeves Pop is a DA steam engine….

I have one and the plans ……just need to build it…

Edited By John Rudd on 20/07/2015 19:35:18

[John RuddParticipant @johnrudd16576]

I should add that the engine can be built single or double acting….

[steamdaveParticipant @steamdave]

Does it have to be a Vee configuration? If not, here's one for you:

[Nathan SharpeParticipant @nathansharpe19746]

Jason B,

Didn't Tel do a write up on MEM? Or am I mixing it up with another type of engine?

Nathan.
