Brad when the box comes up to type your reply just under it to the left is "attachments and other options"
If you click that more will come up and you will see a box "chose file" click that and then select the image on your computer (there is a size limit)
Alyn Foundry:
Hi Brad.
You're obviously well versed in the Sterling "art " !!
I'm looking forward to seeing some of the engines in your collection and in particular the 55Kw generator.
I used to have an agent in the USA, Cliff Schroc? I'm not sure if I've spelt his surname correctly, I heard he'd had some health issues and wasn't trading anymore?
The posting of pictures is fairly easy but as Jason has pointed out there's a size constraint, if they're too big they are disallowed.
Here's a photo of a machined Robinson platform that was cast for me late last year. They're possibly the best that were ever made!
Cheers Graham.

Again, thank you for the help. I am attaching a pic of the Alyn Foundry Robinson, in it's current state of construction. Yes, the top plate is a masterpiece, with the great cores. It is a pleasure to work on. What I like most about this engine is it's accuracy to the full sized engine. I have operated two of the full sized engines that are in the US. Nuff said about the accuracy, compared to other Robinson models.
On one of the other message boards, someone has built a Robinson engine that overheats. that shouldn't happen. It should run all day and not overheat, as I am sure this one will.
In the past, I have built my own burners. I use Propane for fuel and have a difficult time buying a burner, such as a backpacker's camp stove burner that is small enough. They put out way too much heat, so I modify them by fitting a thin brass ring or washer to the top that blocks all the holes except the inner ones. But recently, I have been using a gas furnace pilot light to run my engines. I can buy a model that comes with both natural gas and propane jets, although it no problem to modify the jet hole size.

Regarding my other engines, I will take pics and post them here. This one, I finished this Spring, in time for our N.A.M.E.S show. It is the Poly Models, Anthony Mount, upright Bailey. There are two of the full sized engines existing. One in a museum in Great Britain and the other in the hands of a collector in Australia. It is a beautiful runner, that runs all day at the shows. I now have a pulley mounted to the shaft and will run something with it. I found that an engine that is doing something attracts more attention than one just sitting on the table, running. Especially the ladies can then visualize what these engines were used for. This engine was a dream to build. The drawings were fantastic. I wish I could say that for their Bailey Bee, which is presently under construction. And yes, the hot cap has a copper bottom and I use a choked down camp stove burner that only heats in the center. The engine runs all day on 0.5 of 1 psi. One other thing that I did to this engine is to use no gaskets, but every seal has an O-ring sealing it. Brad Smith, Franklin, WI
Dave Otto:
Nice looking engines Brad.
I had a set of your Bremen walking beam engines that I let my good friend Max talk me out of; it turned out a very nice looking and running model. He wasn't too fired up about the factory color scheme so he did his own thing. I CNC machined the two steel plates for him and made a second set for the other Bremen castings that I have.
