G scale locomotive.

I have done the master/mold/cast on several occasions. In the past if I had good rubber I would make just the one good master and then do several castings so as to have good casts for what I needed. I did this with the 32" Millennium Falcon that I was building to add multiple small details that were all the same, and did so with some tiny details that were on the 5 inch guns on the 1/200 Arizona I was working on. Be aware though that there can be some shrinkage of the resin as it sets up.

I'm looking into the casting thing

Making the valve gear. It's a generic design, like those that could be seen on the turn of the 20th century steam locomotives.
Mine is roughed in right now. Making sure everything is straight and

has clearance from moving parts.
The valve rod was controlled by the engineer from the cab for throttle and direction.

Man y'all got to get down to Kennesaw to that train museum. You can see the casting molds for the parts you're making.

I know we do. The Great locomotive Chase ended around Ringgold, Ga. The spot is just a few miles from us.

Got the valve rod assembly basically done. Now for some detailing. The whole thing needs to be removable to get to the motor if need be. It looks the part enough to me.

Marvelous construction Tim! Where are you getting the pattern from?

Thanks Bob. There were so many different designs used. I based mine on photos (from what you can see in them) of a smaller, earlier type. Again, they were all different. Mine was pretty much made up, governed by what would work on this model. All I'm after is...does it look like it would work...haha.
