Am I off my trolley?...... A new Project!.... No another!!

[monkeyhero97]

Hello all again
Most of you after reading the title are probably saying oh dear... hasn't this teen got enough on his m.e plate. Well, nothing seems to surpress my need for steam and m.e so here goes my thoughts:

I've already got some projects on the cards/ on the go. I have my running chassis of a rail motor, but with a scrap boiler, some serious spending is needed to get a new one, so i've put that on the shelf for the time being. I do have my simplex to be getting on with maintenance.... some basic fiddling such as repairing smokebox hinches , and I also received a Stuart 10V  for my birthday. It seems like the ideal project for me, it will introduce me to many aspects of engineering, and help me learn how to use my mill and lathe. However, once it's done, it's done and I will probably be forgotten about and become a mantle piece. This seems such a waste to me, a small 10V.. what could I do with it..... 

I am a huge industrial tank fan, loves the hunslets, pecketts, barclays and hudswell clarkes........... and also Sentinel's. I know Sirena, a 5" sentinel was published in m.e during the 60s... no one really seems to me building them. Mainly probably because I should imagine they are useless at a club... i.e no power. The engine they use is the Stuart D10, a twin 10V.

My idea is this, bore out the cylinder as much as I can on the 10v ( within reasonable limits of course!) and stick it on a sentinel chassis, not the larger Sirena Sentinel, but the smaller 80HP shunters, like the one used at Cadbury's... such as these ones. So it would only have one Stuart 10V... now this is what I call an under powered loco. Even a 3.5 Tich might have more pulling power. It would like nice though, and introduce me to loco building ( i.e starting a project from scratch and it will introduce me to milling horn blocks, turning wheels etc.... and boiler making). I do not think it would be that complicated as a novice project ( apart from the boiler). 

What are your thoughts? 
Cheers
Marc

Any ppast experinces with sentinel's anyone?

No experience with Sentinels, but some experience with Stuart engines! To be honest I don't think a Stuart 10 will do the job. There isn't much room for extra boring out, and I think you'd be lucky if it pulled itself round the track, let alone you as well. Don't forget, Tich has 2 cylinders, and if memory serves me, they are much bigger than the Stuart 10s cylinder. I don't remember 'Serena', but I suspect that the reason that there are not many (any) about is that they didn't perform very well.
Yes, the prototype is a pretty little thing, but I think you'd be disappointed in the end.
Many of us started with a set of Stuart castings, and as you mentioned, they serve their purpose by teaching you how to use your machines. Build it, learn the lessons, put it on the mantlepiece, thats what mantlepieces are for!

I agree entirely, but i still think it would give me extra experince, even if it could only pull an empty coal wagon! Turning wheels etc.... or maybe I could add another 10V.... and attempt to ride behind it.

Just checked... tich has 11/16" bore, 10v has one 3/4" bore... so slighty larger
I have a bit of hope

Hello,

I like industrial locos too.

Gearing is your friend. A disadvantage of being a single you won't be able to guarantee it will restart where it stops but I guess some small amount of footwork will see to that! I'm coal fired through and through but for this personally I'd consider something like a primus burner.

Regards,

James.

Hello Marc, you would be much better off building the 10v to start. Then you could admire it on the masterpiece whilst getting stuck into a tich Juliet or something similar. You would have to build the 10v anyway. The 10v would be unsuitable in a loco even if it had enough power as being a single cylinder it would not always self start which is why they are not used in marine craft.

Sorry, my mistake. I was thinking of Juliet which has 1" cylinders.

[monkeyhero97]

Hmmmm... what about one eletrically powered axle... with battery in a trolley.... a hybrid ?

[monkeyhero97]

It would really make it an unusual and unique loco! My asthetically, a sentinel!... mechanically... a bit of a mix

[gingerneer]

I have thought along similar lines, about the tiny French vertical boiler loco built by Cockerill. I don't see why it would not work, it might need a nuge to get it going. Give it enough weight for adhesion, my Canterbury Lamb does well and that's just a boiler and a pair of cylinders. A boiler like the GLR vertical boiler (a good start in boiler making) would make more than enough steam. While it would be a 'fun' engine, you could set it up to double as a test boiler. See the bottom of the page for the bista loco

It may make an effective loco if you used a double 10 engine and maybe a reduction gear or chain drive to the axle of around 1.5 to 1

[monkeyhero97]

The problem is the fact I've already got the 10V kit... And unfortunately it is not just a case of buying a second one.. Proportionally I think the small sentinel model with a widen 10V single cylinder would have around the same proportions as the real two types..if you get what I mean . The bigger version ( sirena is model world) has a D10, so widen 10V small version is about right. Whether it's useful or not, probably not but then the full size one of pretty useless.
Boiler wise I would like to have a go at the sentinel sirena boiler, I like the idea of having a vertical chute to fire it, I must see if it is really hard to build.

[monkeyhero97]

Btw, the cockereil are Belgian. But more importantly, they have normal valve gear... So I wouldn't be using the v10, but Yes I do like that loco too, it does exist in 5". I have seen it before

[monkeyhero97]

Thanks for the idea though!
I would plan to get it chain driven, for simplicity
Marc

[monkeyhero97]

A Clayton boiler from the lorry might be simpler. I would have to check and seek advice

Hmm, vertical engine, vertical boiler, gearing, small, that sounds like an 0-4-0 dewinton.

[monkeyhero97]

haha yep! although SG not NG
