I saw this on e-bay and thought that anyone with an engine such as a Stuart No9 may want to go that bit further and make a steam pump based on this full size small steam pump. I'll pass this time as there is another very sexy shaped pump which I have in mind that may make it to being a model
Any takers?

Wouldn't be this one by any chance would it Jason ? :)

If so have you worked out how that cylinder/trunk guide is supported - both views conflict on that
I did think about it as it would make a nice model but have decided to do another engine if anything

I had been looking for some photos of the original engine but the site was knocked down in 1932 so George Watkins did not get to photograph it :wallbang: Grace's Guide and the Clayton Vale community doesn't have anything either :-\

No it's not that one. I see what you mean, one view has it supported by the trunk guide and the other by the cylinder - artistic licence I think it's known as! The other odd thing is that the area of the pump rams looks like it could well be more than that of the piston, probably OK if it were just used for low pressure pumping but would not feed a boiler.
This is the one, I was sent another image but could not work out how the thing operated. This image along with the Patent drawing makes it clearer with another chance to do a rocking valve engine. It's not big and could almost be done 1:1. Not sure if or when it may get built as the list of future projects grows at a faster rate than even I can build them :-[. The same source also sent me photos of an Wall open crank engine he has just got that is believed to be Elmer Wall's first engine and earliest know to exist and has a few different features to the production ones of which only a couple are know so that would make an interesting project as I have liked the look of that engine for a while.

PS Jo the same e-bay seller has an early Bamford Tulip engine for sale that you may want to copy the photos of for when you get round to doing yours :stickpoke: Oh and he also has a set of Robinson "Chippy" X-type castings for sale for those that may not have a set.

Best give members the link to the castings: https://www.ebay.co.uk/itm/A-E-H-Robinson-X-type-gas-engine-model-Alyn-foundry-half-scale/333750790600?hash=item4db518e9c8:g:KEMAAOSw3nJfgye5

Jo, What would you expect these to go for.

More now she has given the link to a greater bidding audience :LittleDevil:
While on the subject of future projects I cam across this 500page book with a lot of illustrations of steam engine details. Not sure if it has come up here before but a good reference for anyone wanting to add that period detail to an engine or find a complete one to base a model on.

My word that's a bit of a beast Jason - know exactly what you mean regarding lists but as you get closer to the end of the perch the idealism tends to wane a bit ;)
Yes the sketch is what it is - a sketch, but done for a 'model' according to the legend. Obviously he knew what he meant :D.
Thanks for the link - great addition to the library :ThumbsUp: Don't think I'll be printing it all off though

Jason,
I thought that as well. I searched Robinson X type and it did not come up so searched for Bamford Tulip and went that route.

I've seen desperate people pay silly money up to £500 for a set :Doh: which is daft as they are still available through Alyn Foundry for much less than that ;)
The seller has really gone out of his way to present the castings by throwing them on that damp gravel ::)
Jo
-
Obviously in order to top up Grahams special coating. :)
-
Hi All.
I've just received a reply from the seller. The engine is number 186 and was originally sold to a Mr W ( Bill ) Sambles in 1998.
He also informed me that there will be an R.L.E. and a Gardner to follow. ;)
Cheers Graham.
-
Graham, any idea what the part top right is meant to be from?
(https://i.ebayimg.com/images/g/w8IAAOSwFN9fgyfq/s-l1600.jpg)
I wonder if he may have been trying to clean up the castings with some heavy grit blasting rather than enhancing the special coating :thinking:
-
Hi Jason.
I'm assuming a casting for a pulley but the cored hole is way too large. Certainly not supplied by me.
On closer inspection I can see two inlet valve castings, very strange!
It doesn't look as though they've been kept in a dry place as the Zinc gear has taken on some heavy oxidisation. Reminds me of my place lol....
Cheers Graham.
-
Graham, any idea what the part top right is meant to be from?
My guess it should go with the Bamford as it is missing its drive pulley (and the bore is about right).
Jo
-
Graham, Jo,
How many castings make up the set and what are they. Is there a complete set in the picture.
Thanks,
Colin

Hi Jo.
I've just followed up on the sellers other items, the Bamford is an early 20's 1 1/2 HP engine with low tension ignition. I wouldn't think the pulley casting is for that.
Cheers Graham.

Hi Colin.
There's actually more than a full set, I noticed an extra inlet valve chest.
Those are later Buckley Foundry castings apart from the water base. You won't have any problems with the Iron at all.
Cheers Graham.
-
Colin, if you zoom into the photo with the name tag you can read the list of what was originally supplied and the next photo in the picture with the paperwork looks to be of the original line up.

Jo, my apologies.
In retrospect, I think you might be correct in your assumption. The Robinson is 1 1/2 " bore with a 1 1/4" cored hole. That pulley casting is quite close!!
Cheers Graham.

Robinson price is starting to go up, are you still in the running Colin?

Wow what a lovely book ...I want one of those ....Fabulous
Thanks for sharing this

Jason, Hopefully. Losing at present. Will be on way back from RAF Duxford when auction ends so need to do a bit of forward planning. I was hoping it would not go for too much of a silly amount.
-
Good Luck Colin,
All this talk of castings has resulted in Surus nesting :facepalm: He has just imported another batch of boxes for storing his castings and no doubt next he will try to make out someone has been stealing them and be demanding more ::)

Well my flight in a Tiger Moth went well. Bit cool. They struggled to get the DH engine to start up but managed in the end. The guy swinging the prop looked worn out by the time it started. The rein seat Spitfire that was doing passenger flights sounded good.
Colin
-
Never mind the flying, did you win the engine :LittleDevil:
-
At £427.00....
A tad under £200.00 increase from the original price of £235.00 back in 1999.
-
Graham what do you think the current cost of a set would be from the new foundry?
J
PS plenty of sawdust on my CNC ;)
-
I did not win. I went to £417
Keep on looking. Or waiting for Graham to dust off his master patterns

Good morning Jason.
Not as much as the previous one we tried. Just the two main castings would get us over £200.00 right off the bat.
I had a call from the foundry that's making me a batch of CHUK 2's, they're getting close to finishing. It will be interesting to see what their Iron is like.
The Robinson kit was one of the stolen plates but luckily I still have the masters.
Cheers Graham.
-
So not far off what Colin was upto if you said the weight of the flywheel would put it at another £100 based on the other two castings and say £100 for the smaller parts, pinion cost on top of that as I assume buyer would now get that direct so a bit more than Jo thought. Which would put it at the same sort of cost as an Economy or Senior from Eng Emp.
Yes it will be interesting to know how those CHUK castings come out especially as I've got a taste for this pattern making lark and may want to get something cast up for myself in the future.
