Nice collection!
I have two of the Tonka kits, but no skills to build them yet :D
I also want to make a little 3 legged stand and a burner for it.
The Buckman stands are usually made with the legs attached to a ring that the boiler lifts in and out of (tight fitting), not permanently attached

Thanks for all the comments guys.
I did run this on steam yesterday, but my video turned out really bad, so I won't be posting it until I redo my steam test on it. I also want to make a little 3 legged stand and a burner for it.
That turned out great 8)
By the way, do you have a steam Tonka?
Nick, here is my story about that;
Many years ago at a garage sale I found this original "American Edelstaal" kit for the Tonka Steam truck.

It was this set of plans that I based the little oscillating steam engine on. Building the first engine exactly as on the plan, and the 2nd a little beefier and inverted.

At the same sale, I found the kits for the Open column launch engine, and the Hudson River Paddle Engine.

As I am sure you know, these kits were put out by American Edelstaal to be built using the Unimat lathe. As a 10 year old back in the mid 60's I really wanted one of these lathes, but we were poor, so of course it never happened.
I have made up for it now..

Just like the others, I also want to see the little beauty run. Really very well built. Congratulations!
-
Very well done Jim!!!
Looking forward to see it run as well :)
-
That is cool , anxiously waiting to see it run.

A doorknob boiler ........ what a brilliant re-purposing!!!

How wonderfully clever and very very creative! I really like it! Well done on the build and design.
Now we all need to see it in action of course :)

woke up and thought, What should I do today? My answer for today was Build a Steam Engine!
I actually started this a few weeks back before I went to Colorado for 10 days. Inspired by Nick's small Buckmans I decided to build a small engine and boiler. Here is what I came up with;
[attachimg=1]
As you can see, I used a brass door knob for the boiler. I machined and Silver soldered a bushing into it that I threaded to accept a plug upon which I intended to mount the engine. I then started looking for plans for a suitable engine. I decided to use my set of plans for the Steam Powered Tonka truck (designed by James Senft) as I figured that would be about the correct size for this project. I initially made the engine exactly as designed, but struggled with how to get the steam up to the intake port.
This morning I redesigned the engine so I could mount it upside down. I machined the entire engine today, assembled it, mounted it to the boiler, and gave it a test run.
Here are a few more pictures.
