Is this what Geoff Malins should have made?

I have been having a play in the workshop again
SillyBilly

I LOVE IT!
rangerssteamtoys

Thats a great model that you have made. very nice but my question is since I'm not to smart with mamods is, was that ever a real mamod model? it would be a nice one if it wasnt.
Mamodman123

I do like that Ian, very quick and smooth runner

Looks kind of strange but in a good way. Two disc cranks, far too crazy for Malins
Chris

Wow, are they going to go up for sale too?

How about a twintandemtwin next?
Steve_S

Beautiful engine!

No, the one that Mamod made is this one, well this is one of my reproduction MFTwins but it is exactly the same

Does that mean FOUR cylinders, now there's a thought

That is the idea, combination of the twin and the tandem.

This was the original Mamod model in 1939

Sigh, I now know what to save up for. I hope they are still available next summer.

Four cylinders would use up the steam much quicker...might need an extra wick. What a sight it would be though!

i've looked at that picture a few times, that is the one that inspired my prototype

As you say MM, its runs very smoothly, i doesn't run with as much vibration as the twin.
Mamodman123

It's the most famous twin MM2 on the net it's the first one I saw anyway

Do you know where it is now Ian? I see that one has the bent frame but some others have the bent piston rod

I'm running this one with a two wick burner but with very small flames. I think you are right about steam consumption so the flame would have to be higher

It has disappeared, it has not been seen at any shows, nor has anyone boasted about owning it.
I know of 5, one person owns 2!
They are all different, some have bent frames others dont , one has bent frame and bent rod. Bases and connecting rod size are also different.

What a sense of satisfaction it must be to pop into the workshop to play & come out with something like this
Beautiful craftsmanship as ever..........."The Mamod that never was"
SillyBilly

I await the 4 cylinder model eagerley !

Its the long lost Post War Prototype MM2, it would sit along side the Prototype SE4 very nicely.
Mister Occlusion

Now *that* is cool

Just needs a PTO in the middle and a really tall lineshaft
Wallace

That's great MF. Very smooth runner
steamyjim

COOOOOOOOL!!!!

I want one! Have you got plans for it?

You want a 4 cylinder one next

Ive got a headache even thinking about making that

No drawings as such just a photocopied twin drawing with lots of scribble on it
steamyjim

Can you scan it for me pleaaaaaaaaaaaaaaaaaaase

The engine mount sketch is a load of workings out with no real picture, just looking at it now it does not make much sense and i did it.
Minor1PJG

Now that is very nice. Don't make it otherwise that will be another one that I'll have to add to my wanted list.

Once again a credit to you Sir! !
Graham-Jilly

very nice MF but where is the drive pully ???
wyvern

Very nice piece of work, I look forward to the 4 cylinder model that will be crazy . you would probably have to use a few more wicks to create enough steam output but then you could always turbocharge it by using a gas burner
Mister Occlusion

And then, at that point of having 4 cylinders and a bigger burner, you'll probably need a bigger boiler too, to have a decent run time.

Hardware upgrades become a vicious cycle

A couple of pics

The 'MM3 MFQuad'
johnreid

Excuse me for my ignorance, but are there no drive pulleys on that?
I run my steamers without driving things, but think that would be a big part of the fun.
tmuir

He only made that engine as a one off for a bit of fun and didn't ever plan on using it to drive anything.
MamodFan

Ok I give in, I will sort some sort of drive out for it.
johnreid

I suppose one could cut a small groove in the flywheel. No big deal, that sure looks like one that I would be happy to just sit and watch without driving anything. It sure is pretty.
oldstuff

Wow! That's just awesome, MF. What an appealing little engine!

The shaft could potentially be the PTO. A spring type band might not fit,
but there looks to be enough clearance for a thin rubber band. You'd have
to be able to take down the shaft to install the band, though.

I like that engine, MF!
Mamodman123

Groove out one or both of the disc cranks, then you'll have the drive
MamodFan

There is enough room to run a standard MM1 pulley in between the engine frame and still have clearance on the chimney
SillyBilly

Very clever yet obvious, nobody ever looks at the simplest answer.
Roly Williams

Now that I really like. It's good to see someone take an established classic and improve on it. Well done

The 4 cylinder version would be a bit gimmicky but good for a laugh. If the cranks were 90 degrees apart, it would be quite smooth (although not perfectly balanced because there would still only be two crank pins).
barry1946

C O N G R A T U LA T I O N S
That is a truely awesome model!!!
I think it would spoil the absoltute poetry of motion you have achieved to stick a pulley on it. The symetry would be ruined and that is a great part of it's beauty!
And like everyone else - I WANT ONE! So off to the workshop - sit about and fantasize!
