waterloo traction engine .29 scale

[sawyer massey]

We started a groop build a waterloo 25 HP side mount
The reason for the scale is a 10 inch pipe works out to boiler diameter so scaling the rest from there

Did you use 3D printing to make the pattern?

Cheers,

If you’re doing cast iron then more info on the melting and casting process, PLEASE.

We are working from a friends full-size engine
5 of us are building them
The drawings I am making up as well as the patterns

As for the casting it is iron
We use an a10 or an a 20 crucible depending on what we are going to poor
I use green sand and spay it with graphite and alcohol
Helps with the chill and the finish of the casting
The foundry is fire on oil

 

[sawyer massey]

That's what the full size engine looks like
Thanks
Todd

This is as far as I am right now

I would love to try my hand at casting, but aluminum is as much as I have hoped for. I am impressed that you are not only casting iron, but getting such beautiful results!

 

[sawyer massey]

Coming along ...goveners are finished 90 % of the main frame one eccentric one in rough cast as well as the strap and crosshead

 

[johnmcc69]

Beautiful castings!
