Coles Worthington Duplex Steam Pump

Would your 1" scale pump be too small for a 1 1/2" scale

are castings needed with the grabcad drawings?

No - guy was just showing what he can do with 2d to 3d.

Kinda thinking no - would not look right

[Odyknuck]

My thoughts also, just thinking out loud I suppose.

I am working on a 1' Mountain and the duplex pump was badly buggered, so I mounted a Coles in its place. Seems to look ok, the Coles sure runs nice.

I am stil searching for the water seal cups for this Cole's Duplex pump.
Any available for purchase?
Thanks

I believe you can get the U-cups you need from Precisionseals.com. Their catalog is on their web page with piece price. I think their minimum order is $20. U-cup part number 005-003 is .375 O.D. x .125 I.D. x .125 long is $5.12 each.

Good luck, Dave
