Coles Models Holt 75 engine model

Post by Rwilliams » Wed Apr 03, 2019 7:59 pm

Long ago Cole's Power Models offered prints and a casting set for the Holt 75 motor. I considered building the model more than once but never did. A friend bought the casting set but was not a machinist. He had a machinist begin working on the castings, but the parts were never completed and returned to him in a box without the prints.

Is it still possible to get a set of prints?

Is there anyone out there offering the crankshaft and camshaft finished and ready to install for this model engine?

The friend stumbled onto a early Samson Iron Works 6 inch centrifugal pump and scaled it down and had castings made. The plan is to bolt the finished engine on a bed frame connected to the 1/6 scale Samson pump when completed and have it appear like many of the vintage water pumps used to pump water from the rivers years ago for irrigation in the San Joaquin Valley of Ca.

If we can find the drawings and a source for the cam and crank it will make for a beautiful model like never seen before.

I am also very interested in a set of drawings for the Holt engine.

Coles was sold and is now defunct, I spoke with the current owner about two years ago and he told me that he would sell the entire business for $100k.
