STUART MODEL ENGINES

[lancelot]

Hello Tel and Ron,
advice followed to the letter, after tweaking a few fiddly bits and bobs, it is now running like a sowing machine on 20 lbs air pressure, great to watch after all the work, will now have a look round for castings to build a much bigger one.
Thank you again for the help.
All the best for now,
John.

Hi John
Excellent, it's great when they finally run on air [it's even better on steam!]
If you're looking for a bigger one, I've just about finished a Victoria, it's an impressive model and different enough from the smaller engines to make it an interesting project, worth considering.

Great John - nuthin' beats that buzz eh?

While we're on the subject of Stuarts - does anyone have the drawings of the reversing gear for the 10V or Twin that they could scan for me? I 'ad it, but someone must of needed it more than me

[ron]

Hi Tel
I'm pretty sure I've got them, if I can find them I'll e-mail it to you.
Ron

[Tel]

Thanks Ron, that would be appreciated

[ron]

Sorry Tel
It's a scan of the building instructions with photos and diagrams but no drawings with sizes I've got.
Ron

Hello Tel,
do not have the drawings myself, nothing doing on the net, thought some one might have downloaded them somewhere, but what I spotted, if you do manage to get them, apparently there are ''ERRORS'' in the drawing, ckeck out ALAN STEPNEYS site,...

All the best for now,
John.

[Tel]

Thanks blokes. I dare say I can figure it out from the engine with a bit of trial and error.

Tel
I've found a set of reverse gear plans if you still want them.
Ron

[Tel]

Yes please Ron ;D

[ron]

Tel
It's on it's way, I'm just back from holiday,
Ron

[Tel]

Arrived safely squire - thanks again

Hello all,
finally decided to run my engines on steam...10v and Score...I have a S/T Babcock 504 boiler set up and piped to both engines for a trial run...HILARIOUS...steam flying out of every possible orifice it could (a FEW leaks) both engines gave a bit of a kick but would not turn over... boiler was developing 65 lbs. pressure...So would I be right in that the timing needs adjusting so as to run on steam, and how do I do that ? Is it a must to run on Steam Oil with a displacement lubricator for each engine ? Would it be advisable to fit a steam pressure control valve at each engine intake ? Last question... in the pipe working from boiler to engines the internal diameter is reduced i/e large outlet at boiler smaller inlet at valve chest on engines...may this affect the running of engines ?
I hope some one can answer,
All the best for now,
John.

Come on John, let's have a picture of your leaky kettles oozing steam

[lancelot]

Hi Paul,
much as I would love to demonstrate my cleverly executed silver soldering, and it is...I would more rather that it looked the part at least. I am awaiting with anticipation the collective wisdom from our readers on the subjects of ...Valve timing adjustment for Steam...the LAY mans approach...Lubricators and Steam Oil and those sorts of things...If and When I manage to obtain the answers, Then I hope to post some photos Worth showing...That is of course after I have cured all the leaks ;D
All the best for now,
John.

[paul]

I like engines that leak at least a little steam

[spurley]

Hi John

I'd like to come and have a look at the new 'plant' when I'm free however everything is conspiring against me at the moment. I am getting home at the weekends but will be flying to Gatwick Sunday evening for the next two weeks so time at home is a little short at present.

Maybe get a chance this Saturday?

Cheers

Brian

Hi Brian,
a welcome voice in the wilderness Of course, ... Sent you a personal message,
All the best for now,
John.

Congratulations John, I can still remember the buzz I got (and the engine made) when my ST 10V first ran on air way back then (about 1980). The engine is still running fine after many, many hours of heavy running on both steam & air and it has done quite a few 8 & 10 hour non stop runs.

Since this old thread has been revived, I thought that I'd ask you about this: for your non-stop runs, how did you keep your crankshaft properly lubricated? I have a Score that I am in the process of setting up to use, eventually, for the somewhat eccentric purpose of powering a small computer, and, as such, it would need to run at high speed for a long time; how would I keep the crankshaft properly lubricated without regularly stopping it to oil it? Where the crankshaft sits in the static part of the engine, there are oiler cups, but there are none where the crankshaft meets the rods from the pistons or the eccentrics, and these, I imagine, are the parts that would wear the most.

TEL,
Are you still in need of reversing gear drawings for the 10? I have two to select from . . . those originally published by Mssrs Stuarts, and a gear published in ME, Vol.131-No.3266 (01 Feb 1965) by Cdr. Alwayn Greenhalgh (RN Ret.) for a tug power plant. The only difference appears to be the way the reversing arms feed their motion to the links. I haven't compared the two to see if there is another significant difference. Unfortunately I have no way of scanning these at the moment.
