Coles Worthington Model Steam Pump

My build of the Countess

I have a Keith Watson Worthington duplex pump casting set that has full plans and I started machining the main body .
Not sure what scale it is but its quite large probably to suit his 2.5 scale engines he has done over the years , the body measures about 9.5" long with I think 5/8 bore pistons i'm sure it moves quite a bit of water when required .
Keith was a very good salesman and he convinced me to buy it off him for the challenger as I was going to put it in the tender which will not happen now as I have SS injectors .
If any one is interested I will dig out the plans and the rest of the castings , postage may not be cheap this is a heavy casting set .

it takes very little work to modify a bill van brocklin vertical pump to be a horizontal. i have one under the cab of my 3/4" hudson - looks like a stoker engine but is actually a water pump.

runs fine and a proven design requiring no castings.

For something similar to the Coles Worthington pump look at the Mich-Cal No2 pump drawings in Live Steam Oct 1986 and Dec 1986. This might be what you want. This uses no castings.

Dave:
What's left of my memory thinks someone in Australia has some nice castings for a similar pump. I don't remember where but you might try contacting these:
sales@ejwinter.com.au
sales@dncsystems.dynalias.com
warrick_sandberg@hotmail.com
I know for certain that there was an article about it in Australian Model Engineering magazine. You can contact them here: https://www.ameng.com.au/contact_the_au ... gazine.htm

The castings I have are Australian ones from Keith Watson ( Wato Loco Works ).

Also there is a similar duplex pump from the UK - Southworth Engines in Chesterfield UK and a build series in UK model engineer magazine -

June 93 and Jan 94

There are articles in the Australian Model Engineering back issues 113, 114, 115, and 117 but they used castings to build the pump
