3D printed dome saddles for my Forney

Posted by Gerd on Wednesday, 12 August 2015 (Comments Closed)


last summer, I made a test run with 3D printed parts for my large-scale Forney and today, I like to show you the results.

I’m into 3D printing for some time now, but used it mostly for smaller scales. When I was going to add the missing dome saddle on boiler of my Forney, I got the idea to test this part in 3D printed steel. First of all, I didn’t had a piece of metal to work with and by using 3D-printing, I could spare a lot of time and work which is needed to make such a saddle. I ordered the saddle at Shapeways and got it 2 weeks later and it fits perfect.

One can determine the stepping on the bend, but with some paint and weathering on it, it’s hard to see anymore.

The walls are just 1.5mm thick and the material is stainless steel. The price was 53,-€ and okay for me. Remember, otherwise I had to buy a piece of metal and spend several hours on the mill and lathe.

I was very happy with the result and just ordered another ring to install the sand dome which is still missing. This will cost another 37,-€ and should arrive in 2 weeks. This time I also added the fittings for the sand pipes. The rest of the sand dome will be made from pipe and steel.
