Galloway Castings

(1/12) > >>

PatJ:
I started making a bar-stock Galloway, not to any particular scale, but with flywheels about 10" dia.
As I recall, the 1/4 scale was smaller than I wanted, and the 1/3 scale was too big, so I think I was between those sizes.

This was a few years back, and just learning 3D.

I have since got into backyard castings, and so I will revisit this engine and try to cast a one-piece frame and cylinder from cast iron.
I don't really care for the bolted frame/cylinder kit designs since that is not how the originals were made.

I think I have enough photos to go by, and my dad had two that were 7.5 hp, one being a round rod.
I remember the simplicity of this engine, and how well it ran.

Here is a piston I made from gray iron bar stock, but I need to cast this to make it lighter.
And my first attempt at a 3D flywheel, which is only partially correct.

PatJ:
My dad's forged-rod Galloway.

Jasonb:
Pat the 10" flywheel is about right for a 1/3scale 5HP engine but if you are going for your Dads engine then as you say something like 3/10 scale. You will have some fun with the cores if you do a single casting to get the water jacket around the cylinder.

Here is a challenge for you, cast wheels for a Hand portable cart :LittleDevil: Those 5/32" dia spokes won't be easy to get the iron to flow down. Should be able to post my finished wheels next week. ;)

PatJ:
I am not really trying to match a particular engine, just trying to find a convenient size that will fit the lathe and not have fiddly sized parts.

I noticed that the galloway has a bolt-on water hopper, and I would make mine that way.

Many of the hit-and-miss engines did have the water hopper cast as an integral part of the cylinder and frame, but I would have to think about that core.  Obvioiusly if they use to make them that way, then they can once again be made that way.

For those wheels, I would use steel rods, and cast the hub and rim around the rods, as was done on some of the old John Deere tractor wheels.

PatJ:
Hey Jason, I found your Galloway thread:

Great work as usual.
