New Steam Pipes on William

Here are some pics of the steam pipes I fitted to my William that go from the up-turned exhaust ports on the slip valve blocks through the chassis, round the new boiler band and into the back of the smoke stack - real steam now comes out of a William's chimney!!

Looks great MD! A real improvment!

Very well done. Look forward to a video of that in action.

Are the pipes just a push fit into the valve block or have you soldered them in?

Another variation I see from your photos - my William does not have that slot cut into the false smokebox fairing.

They are just push fit, works ok.  I thought I would leave un-soldered as it would be easier to remove pistons for servicing, etc.

You have the very latest version.  The slit was one of two, the other being in the cap floor. It was intended for a remote control option, but Mamod never got round to it.  The other differences on your one is the boiler band is fitted inside the smoke box rather than the outside, and you have a different knob, made from brass, but by the sound of it just as bad and prone to failier.  My one unscrews when you don't want it to.

I never realised that the steam didn't exit out the chimney, it needs to do that, a simple but well needed mod. Good one.
CCairns

tmuir You've obviously forgotten your posting on my William review where I asked would Titan's idea of piping the exhaust steam to the chimney not introduce a back pressure problem.

Mamodevon Thanks for your prompt reply to my queries. It seems incredible that this loco has gone through so many changes in such a relatively short time. Mine does have the slot in the cab floor, but what was this R/C going to control as the regulator is mounted on top of the boiler? Were they going to fit a regulator within the steam block at the front of the chassis, which is what Cheddar Models did with the 'Iver'? My boiler band goes on the outside of the smokebox fairing but is rivetted to that fairing and not the running plate like yours ( see my photos in this posting again http://modelsteam.myfreeforum.org/about7103.html ). And mine is not the latest version, as Titan's has a different steam block and lubricator fitting between the chassis (see his posting here http://modelsteam.myfreeforum.org/about7304.html ). My block is the same as that fitted to an SP6 that I got recently.

I understand that they had a few problems with the very early ones.  My first William Jubilee is number 004 and needed some help.

On the proptotype of this new vervion loco, they had what looked like the old boiler, with whistle near the cab end. This suggests it may have been intended to have a regulator in the cab? Also, if you look at the prototype pics on my website page on locos, you can see some large brass thing in the cab, which may have been a gas tank, or maybe something else??

Who knows, possibly

Ah, when I removed the aluminium band, there where two holes on the side about where your rivets are.

And mine is not the latest version, as Titan's has a different steam block and lubricator fitting between the chassis (see his posting here http://modelsteam.myfreeforum.org/about7304.html ).

I saw that, I wonder what inprovements it has made, or if it is just a mire economical method of production?

Chris Cairns.


Another slight change I have just noticed is the extra chassis spacer you have behind the rear wheels. None of mine have that.  Also, my two earlyer Jubilee locos don't have the red tube sleave between the gas valve and the cab hole, yet my green william does.

This green William came in a set, which has a green passenger coach, whilst all the adverts and box photos show this coach in red.

I have another two williams and another Jubilee coming over from a trader in Germany soon.  One of the Williams is new, so it will interesting see if any changes have been made for the German market.

Excellent job there!

Must be the new craze for Mamod, no exhaust to chimneys  
CCairns

Yes the SP6 does not have the exhaust piped to the chimney, but it uses the SP5 baseplate which has holes under the chimney so I assume the new style SP5 does have a piped exhaust.

Chris Cairns.
steamyjim

I dont think the new SP5 does
Chris

neatly done, good work.
Lewis

who said sp6  

yeh the sp6s worst problem is that it has got an exhaust to the chimney its just a hole in the bottom of the block. This then results in crap spraying everywhere.  

The new sp5 is the same no exhaust but the old sp5 does have an exhaust to the chimney and even a little sponge in the best to soak up water.  

Anyways nice mod on the loco bet it atually has some sound as well now  

Did it have an exhaust before or did the steam just come out of a hole like my sp6 ?

The new SP5 doesn't have the exhaust   so no idea why the base is drilled?

another one of mamods little things bit like why they put 2 rivets in the engine frame on an sp2

The brand new one?

Dunno, only thing I can think about is to stop the engine frame turning so the solder joint can't be broken. Looks pretty poor on mine, neither is the soldering any good at all  

Apart from that i'm sure it's fine  
Lewis

just makes no sence to me

remember those mm2s which are just held on by the strap

Yup! you have to be careful with them  

I don't think not having exhaust is a problem, but on a loco it is a must!

great mod well done Titan

Excellent job. Very neat!

Actually its Mamodeven's mod, and very neatly done too. I may have had the original idea, but I have not implemented it just yet!

And I am not likely to get it done before STIA, as there are many things I want to do with the portable layout, as well as a couple of outstanding jobs on Titan.

I also want to do a bunker/cab back for William, but that will have to wait too!

There have been quite a number of mods done to William in the course of production - I understand that originally it was to have an in cab regulator and a whistle. However it seems that it is unlikely to get further mods - not in the near future at least. It sounds that Mamod have spent too much time fiddling with the loco to get it reasonable, and that now most of them appear to be running OK out of the box it is time to sit back and start making some profit from them.

My assumption that the SP6's baseplate was used on the SP5 is wrong. Having just looked at the SP6 & SP5 on the Forest Classics website their photos quite clearly show that the SP5 engine frame is smaller than the SP6 engine frame, so hole for flywheel is in different places.

Has anyone in the Forum got a new SP5?

So it looks like the SP6 has been subjected to the same change process as the William. Indeed on my SP6 box it states that there will be a gas conversion, but this does not seemed to have surfaced yet.

Looks great Chris!

On my sp6 box box its says theres a mamod SP7  

i emailed forest classics about it a while ago and he said to watch this space
CCairns

Yes my box also has the instructions for a SP6 & SP7 as well.
Lewis

hope they do bring out an sp7 because it will certainly be on my list
