Mamod piston valve traction engine videoFinally, with the help of some compression software and the use of a better connection its uploaded
Hope you like it, it willl at least show you how it runs. Cheers, Wyvern |

I'm sorry guys, but I really like that 
Far better than I first thought!!! Must buy one if I see one second hand! |
||||||
| syrtismajor |
Very cool!
Where does the exhaust steam go? I know it doesn't vent up the chimney, and it can't just vanish! Will still carry on with 'Sovereign' though, but may buy one if I see it cheap |
||||||
| wyvern |
Sounds like you are one of the converted!
Seriously though glad you liked it, its simply a joy to watch ticking over. I am surprised mamod doesn't video their models. |
||||||
| wyvern |
Unfortunately the exhaust steam goes out the bottom of the valve block like lewis' sp6. I may at some point in the future connect it to the chimney with 3mm pipe. When you start the model up you have to remove a bit of condensate 6 turns of the flywheel. I guess its much easier to remove it without an exhaust. I have had to improve the sealing on the regulator using carbon string wrapped around the regulator spindle to improve the performance of the model, and it now goes like a dream
|
||||||
| syrtismajor |
Sounds like a great engine! Strange with all the rubbish that Mamod seem to be churning out, they pop up with this! Is a shame about the exhaust though. Would it better to use larger than 3mm for any pipe you may install? That way it will be easier for the condensate to travel and reduce any possible effect on the performance? It may look a bit daft though 
Either way, that is a very nice engine you have there! |
||||||
| wyvern |
Yes, actually I think 6mm would be better so as to minimise the effect on performance. When I recover from the injury to my thumb I may also make some tubes to sit around the piston valve and keep them better lubricated (it would be a removable modification). Also If I were to add an exhaust I would get a second valve block and tap some screw thread holes M2 possibly and join the pipe with two m2 nuts and a gasket. Unfortunately this would mean I would have to drill into the smokebox. The other option is to pipe it through the original TE1A holes, but that would most likely leave the condensate stuck at the bottom of the pipe.
It is interesting to note it has two superheater pipes at the bottom of the boiler There are certainly improvements that could be made, but overall its great!

I really dig (dig=like) it too. I can't wait to try my Mercer Type 2!!!!!!!!!!!!
well done Mamod ! 
|

| IndianaRog |
Wyvern, a very impressive little TE you have there, nice to see the new version in video form...I've just seen pictures up to this point.
Could be Mamod has a winner there!! |
||||||
| tmuir |
Thats great to see. Runs much more smoothly and at a more realistic speed than the standard Tes. Guessing it will be a while before I can get one second hand though. 
Definately a step in the right direction. Shame they didn't just put a set of drain cocks on it to let you open to drain condensate and then they could of put on the exhaust pipe but all in all a winner I would say. |
||||||
| Wallace |
Ok, I just replied to the other post of it.
But that is a fantastic runner, and certainly seems to have more power than a oscillating type. Just great!! |
||||||
| Graham-Jilly |
Wow what a stunner of an engine. why didnt they come out with those years agao
Love it want one 
|
||||||
| wyvern |
I kind of hope mamod does well with this one, it would be good if the company could remain in the UK. With regard to putting on drain cocks it would be really good but would simply be too expensive for this model.
I have to admit I do feel like a mamod salesman! Thinking about it I dont think the William locomotive would exhaust to the chimney either as it uses the same cylinder and valve block. This is certainly alot better than "Harry" what were they thinking
I think what mamod really need to concentrate on is quality control |
||||||
| Wallace |
Wyvern, I think you did a great job with that video, ie, you showed it in action.
Way back ages ago, I think from memory I wasn't a fan of the engine. Only cos of the look, bulkiness of the cylinder. But mate, that vid certainly changed my opinion of it. It was just great to watch, and nice to see it running. I think very differently of it now. Nice stuff |
||||||
| sparky |
very smart, i definatley want to get one

Mamod are BACK!
What a great TE! I may get one

Right, in the past I have been a critic of the new slide valve TE.
After seeing your video, my view is completly different. Mamod are onto a winner with this one. |
||||||
| wyvern |
It certainly makes a difference when you see it working.
When I was talking to a guy at mamod they told me the Showmans model would probably be out in october this year and may have headlights as one of the new features. Hope they give it a dynamo bracket attached to the smokebox as it would look much better. Mamod are back! now all they need to do is throw harry in the bin and start producing more like this. The engine would be perfect for a steam wagon but it is too big to simply replace the oscillating cylinder on the SW1. On the vid so my brother could follow it I didn't run it at full speed. But at full chat because of oil that often collects between tyres and the rim when running in a circle on my floor they tend to slip off because of the g-forces. Sounds a little crazy for a traction engine
|
||||||
| tmuir |
Yes I agree with you Wyvern. Dump Harry, it has to be the most ugly thing they ever made and make a few more models with the valve engine fitted.
I would like to see it on the roadster for a start. |
||||||
| wyvern |
I have always thought the valve engine perfect for a roadster, I'm sure you could get some serious speed out of it. Ideally a RC gas fired roadster now that would be good.
|
||||||
| tmuir |
Now that would be nice. I have a near new roadster, I've fired it 3 or 4 times and previous owner I would say only twice. I love the look of the Roadster and wanted one for 21 years before I finally got a chance to owner one but was a bit disappointed by it performance mainly due to how heavy it is. Mamod's new engine could solve those problems. |
||||||
| wyvern |
I heard that the lemans rc car stalls very easily if it is cornered too sharply. It would certainly stall less and have far more torque with the pistonvalve unit. A gas burner would help it to operate better out doors, reducing the effect of the wind on the burner, which was a problem a guy know as "crabfu" (the guy who made the turbine snowmobile) experienced when he tried to operate his outdoors. | ||||||
| Mamodman123 |
the Lemans racer should be better as its a twin cylinder! I would like to see the DV1 or the bus have one, i think they need it more
|
||||||
| Lewis |
nice vid mate
jsut shows the mamod slide valves arent that bad after all (i have the sp6 stationary slidevalve) also it is more powerfull becuase in a slide valve almost no steam leaks out of the cylinder but in the ocsliators they do
a great engine
|
||||||
| Mamodman123 |
You going to get one Lew! would be good next to your SP6
|
||||||
| Lewis |
maydo someday now i have seen how good they are id get the roller though
|
||||||
| Mamodman123 |
Yeah they are good! we underestimated Mamod to be honest. I'm the first to admit I was wrong about some of their new stuff! I'd get the TE, but the roller looks good too
|
||||||
| Lewis |
id say the only bad models mamod make is the sp5 | ||||||
| Mamodman123 |
Possibly, although I want to see one for myself to pass judgement
|
||||||
| tmuir |
Mamod should of sent you one of their new traction engines ages ago MM you may of personally turned thier business around for them.
Thier new slogen could be "MM says its ok  '
|
||||||
| Lewis |
MM aproved
|
||||||
| Mamodman123 |
Aye! MM's stamp of approval  only the best, forget the rest
|
||||||
| wyvern |
Cheers Lewis. I don't think the TE is as well thought out as the SP6 but its still great. Now with Mamodmans' seal of approval they should fly of the shelves!
|
||||||
| Lewis |
aye
does mm give my sp6 the seal of approval 
|
||||||

I absolutely love it Wyvern. I was going to ask for one for my birthday, but the opportunity arose to get a SW1 (which I've always wanted) so I got that instead. Although I now know what I'll be asking for nearer Christmas! | ||||||
| steamyjim |
apsaloutley amazing. when i saw them at the factory i thought they were terrible but that vid has changed my mind. seriously considering getting one.
bit of news on the piston valve showmans i got when i met forest classics on the weekend. its out now but its going to be so bloody expensive about £230-£250 or was it £330 anyway something like that.
|
||||||
| wyvern |
Hi steamyjim, do you mean that they have finalized the design and will be releasing it shortly (do you know when?). Do you have any idea of the features (headlights etc). You say it is expensive, and it seems it will be, that is a massive hike of £90 over my goliath.
Well, if the model is impressive enough collectors/ steam enthusiast will pay that kind of money. After all Dr mercers sell, all be it at lower volumes I would imagine mamod wants to achieve. I was going to wait for the showmans, but I simply couldn't wait a year so I bought the goliath. Can't say I regret it, but I am REALLY looking forward to the showmans, I just hope they don't do too much cost cutting and do this flagship model really well. |
||||||
| steamyjim |
not sure of the features sorry
i only asked him when it was coming out he didnt give me an exact date but he said it may be out already or very soon (mamod arent good at information ) email him about it
|
||||||
| Stitch |
mate, that is excellent. I didn't realise they ran so fast! | ||||||
| wyvern |
I appreciate that this isn't a video but it is related to the topic of this thread:
I have just got an image of the new showmans model , which Phil from forest classics informed me can be obtained within 10 days. It seems to be part of a mamod "Specials" range. As I expected it is the piston valve tractor with the showmans bits, still an improvement, but I would have liked some extra bits (dynamo perch bracket attached to the smokebox.
you can see it here: http://i201.photobucket.com/albums/aa184/wyvern2007/CCE00000.jpg |
||||||
| steamyjim |
quite like that
very expensive for what it is if you think about it. i mean a dynamo and a longer canopy ect doesnt cost that much wouldnt it be cheaper to do it yourself and you could make a better job of it aswell |
||||||
| wyvern |
I have been thinking of making my own showmans engine for a while, with the idea of taking a standard TE1a and adding a dynamo perch bracket attached to the smoke box. I would probably purchase a flywheel from mamod. and put a reduction pulley shaft on it behind the whistle to gear its drive to the wheels down.
Although really the model would work better with a TE1 as the base, I couldn't bring myself to cut one up unless it was in a real state. I would probably only use it as a stationary model. The other option would be to go the whole hog and produce a model like soveriegn being built by syrtismajor(double acting cylinder, gear drive etc). |
||||||
| syrtismajor |
Insert the phrase 'attempting to produce' in there somewhere! I'm doing it to a TE1a as I couldn't bring my self to cut up an old one either, the good news is that I think all my plans may work. . . |
||||||
| Chris |
I've been away so only just seen your video of the new TE. Very nice indeed.
A great runner. I have been waiting for someone to post a video of it. Would be good if the steam came out of the chimney, but it is still a very good runner. |

| SillyBilly |
That sounds like a PROPER traction engine! | ||||||
