Hi Barry, Thanks for you prompt reply.
I know where you are coming from re the pumps being finniky.
The 6" Southworth designed pump I built was a couple of re workings before it was reliable and that is with the outside valve gear. (Although the 12" tall version worked fine from the word gobut even that need some mods to the original design)
I guess I'll have a go at building a Westinghouse style with about 1 1/2" to 2" bore steam cylinder and see how it works out in the larger size as a water feed pump. There are a few post on the internet by people who have built them, apart from the commercial guys, but they are mostly photos of the components and text but no drawings. The principle is the same I suppose, a valve driven from an extended piston rod driving a shuttle valve controlling steam to the piston.
If I can find a "roundtuit" I'll have a go though at four score years and a bit I'll have to get a wriggle on.
Cheers
John

Don Young described a single cylinder Westinghouse pump for air, basically to the Van Brocklin design, for his 7.25"g Terrier. It appeared in one of the later editions of Locomotives Large and Small. If you are interested, I can look out the reference or scan the articles and drawings for you.

Hi Malcolm,
That is a very kind offer.
I bought some drawing from a firm called C.A Street and Sons in the USA and it says on the drawing
des. by W. V. B. I take that to mean Van Brocklin. The drawings were not very good and I never really got started, instead building two vertical Southworth pumps (6" and 12 "), both from very good drawings and both of which work well.
I wonder if Don Young got a better take on the original V. B. design which by all accounts was not particularly successful.
I will of course be pleased to reimburse you for any costs involved, postage etc.
Cheers
John

I have many LL&S mags but not the complete set and I am certain I do not have the pump drawings issue. llewellynbikes@powerup.com.au |

No problem Darrell. It won't be for a few days as I have to use the office scanner and am working off site until Wednesday!

Hello Malcolm
Ref yours of 13th Nov at 5-59 and 14th Nov at 11-27 (and mine of 14th at 7-28), , I wonder if you have been able to scan the Drawings as mentioned, they would be extremely well received I can assure you.
We are not a million miles apart, I am in Maldon and my family all live in St Ives area. We built a LYN and a TAW in 7 1/4" for the Railway at the MUSEUM of POWER at Langford (www.museumofpower.org.uk).
Cheers
John

Hi John,
Yes, I have scanned them and sent you a PM asking for an email address I can send them to. Once I have that, they are one click away!
Best wishes
Malcolm

The owner of 5035 decided to weather it after i finished building it. It looks good but i couldn't do it myself.  |

I love the little extra details like the water bag hanging on the side of 5035's tender. Little details like that bring models to life for me along with lots of happy childhood memories them bringing goods trains up the grade into Katoomba or stopped at the Brakes Landmark waiting to descend the mountains to Sydney.

I'm really enjoying this thread. I know you've built a lot of locos but I haven't seen most of them.
Do you have any photos of wagons you've made?

I have a few pictures of wagons and a lot more of engines but they are all on printed photos and i will have to scan them and then post them.

3821 was the first NSW 'C38' that I made and the other engine 3901 was built at the same time. It was never built in full size and is a hypothetical upgrade on the 38.  |
