 A more sober question     your throttle valve the elliptical bit does it tend to close or open,  e.g. does it point towards the gas flow like a car carb. blow shut or is it the other way

one way it will be gas assisted to shut and the other it will be blown open

looking great now

Stew, it looks spot on that ... shame you've made it so the valve closes more the slower it goes ....

Didn't know ther was two spellings  , but they both give the same result:- drink too much and you fall over 

Stew

Thanks Pete/Nick

Glad you brought that up, I've bin trying to get my head around that for some time, and keep thinking my way in and out of which way to mount it 

I quite like the idea of it working against the flow that way it will self close and I may be able to do without the spring, it will be quite easy to change it round by just simply flipping the valve over, so I'll probably try it both way.


Stew

[lordedmond]

I have activated the single brain cell and gave it more thought with it assisted shut by the gas ( steam/air ) it may not reopen or the other way round it would not open


Whisky  try some http://www.glenfarclas.co.uk/en/pages/78,105_Cask_Strength.html


it is very good, dark like rum and undiluted from the cask about 14 degrees proof 


That must be why only one cell is active

Interesting one this
In respect of the butterfly valve-
I would have thought that if pivoted in the middle, air flow would neither open nor close it being the same area on both sides.
But... just playing about I now have come to the conclusion it would always try to close it, at least until it were nearly shut.
It's the same both ways though so turning it round will make no difference , again if, as I assumed, it is pivoted in the middle?

If I've got my head round things right the spring is needed to hold it open then the balls flying out against the resistance of the spring close the valve, so, spring strength varies how much it closes at a given speed.

Nice build anyhow 

Steve.

[sbwhart]

Thanks for your input Steve/Stuart it's a bit of a brain teaser  .

Stuart i've never had a liking for whisky or whiskey, I'm a beer and wine man myself  .

Thought I'd go   and post a few pics of Islay

There's lots of Gray seals about the Common seal are not so common

They like to lie on rocks just under the surface and look like huge black Bananas.

Back on topic I changed the spring on the governor for something a bit lighter and made a video the shot looking down is a bit out of focus but you can see the butterfly valve working.

Enjoy

I can't stand the stuff.


Quick question Stew relating to my flippant comment before; in your video it sounds like you've got the valve closed by the spring i.e. when the balls are in? If that's the case, the faster the engine goes, the more the balls will swing out and the more the valve will open which will make it go faster. Shouldn't it work the other way around so as you put a load on the engine and it slows down, the balls move inwards due to less speed which opens the valve more to give the extra power necessary to drive the load?

Sorry if it's me getting my knickers in a twist. Can't quite see down the hole whether it's opening or closing./

Cheers

Hi Nick

Sorry I missed your ? before,

I've had the same ? asked on HMEN the valve does close the faster the engine goes, you can't see this very well on the video as your looking down a hole and its not in focus, I'll have to do a bit of experimenting with it regards to pully size, spring loading, and input air pressure via a control valve, and running speed.

This morning I've just completed strippped the engine down for painting and a rebuild, I'll be adding a control valve, oilers, and bling as I build it back up, I have an head ache in the crank to fix as well: I'm also going to build it a brick wall  

Stew

[Bogstandard]

Stew,

If you would like to make your 'brick wall' out of some hardwood (you could cut the mortar in with a ball end cutter), I have a load of thick and wide planks of oak here that would do the job admirably.

It wood be dead simple to simulate and do using your dro.


John

[sbwhart]

That sounds like a good idea John.

I'll have to be carfull with hardwood as I've developed an alergy too it, but I may be OK with good old English oak.

Hi Peter thanks for the scale brick link, unfortunatly I think they will be too small a scale the engine is approx 1/3 full size.

Stew

[klank]

Hi Stew - just saw your video - are you a master watchmaker or what?

I don't know if this might help - I "bricked and stone floored" a small plant using real brick/stone materials from "Richard Stacey" - http://www.richardstacey.com/
They do stone/brickwork/slate in all kinds of scale sizes.

If its ok to put this photo here? - I used their products to "brickwall" a Stuart H10/Boiler plant :-


Potty Over Crank Wall Engine

I don't want to go "off topic" - this is just to show what their stuff looks like. I used cyano to glue each brick onto wood, coated in Plasticard plus a thin wash of white glue, let down with water.
Courses were "pointed" with Stacey's own mix.

With all respects

Peter

[sbwhart]

Hi Peter

Thanks for your kind comments and link to the brick supplier, I think they will be too small, the engine is 1/3 full size.

I've stripped the engine down and started to paint it, for the wall I,m planning to use chip board with scale bricks cut into it with a radius cutter I'll then paint the bricks different tones of orange and paint the pointing a dirty grey, I'm hopping that will look OK.

I'll post some pictures in a few days.

Shop time is a little scares at the moments as I've got my 86 year old father seriously ill in hospital.


Thanks again

Slowly making a bit of progress.

Made a start on painting the engine up, got some cans of spray paint and acid etch primer for the none ferrous bits, and made a start masking parts up.

Potty Over Crank Wall Engine

I also spent quite a bit of time rounding the sharp edges off, paint hate sharps corners it just pulls away from them, and giving stuff a good clean and a degrease in my ultrasonic cleaner, the bits that were too big to fit in it went in the dishwasher.

I used the milliput to fill the corners of the base in so that it would look like a casting.

Potty Over Crank Wall Engine

The non ferrous parts were primed with acid etch using an air brush, this is nasty stuff so be sure to read and understand the instructions.

Potty Over Crank Wall Engine

These are the bits sprayed up I'm going to leave them for a few days to harden off before I do anything to them.

Potty Over Crank Wall Engine

Made a start on the stop valve' turned the body up and milled a flat to take the input flange with a small hole to line the flange up, turned the flange with a small boss to locate in the hole.

And silver soldered the two together.

Mill the flange to width locate on its centre drill the air way and the clamp holes.

The holes in the top and bottom have a different orientation, so the flange was used to get the orientation correct.

Her we have the body finished.

Forgot to add the PDF drawings for the butterfly valve and the stop valve.

Very nice Stew, I cannot wait to see it finnished, Dont forget you now a sand blasting facilety close to you, they even give you drinks while you use there machine, nice case it is in. have you been there latley?

peter

[sbwhart]

 

I just missed out at giving that sand blaster a try, Pete, all the bits were masked up and primed when I found out about it.

Stew

[HS93]

It's a handy place to go that , the owner is a bit Grumpy but his dog is great.

Good choice of colour stew 

sure looks great ,,,,,,impressed at the way the base has turned out 


Rob

[NickG]

Yep, really looks the part Stew.  Everybody is nearing completion of projects - this is depressing!

Very nice
