First Engine. A successful Sterling engine

[DOC123]

Dear All
I purchased a 9x20 lathe to make parts to use on my telescope but decided to try to make an engine as practice. I bought a kit of bar stock with plans and the result was a little sterling engine.
I am not an engineer but a medico so this has been quite a learning process.
Some images are below.

This is turning the central block from a cylinder of aluminium.

Milling the pillar on the lathe using a little end mill from a dremel tool.

making the piston shaft.

the finished engine.

Also I have a video of the little engine going here.

Thanks all.
The telescope parts I've made are pretty boring so far. An example is below. It is used to accurately attach a camera to the scope.

The kit came from here
http://cgi.ebay.com.au/A1-3-Stirlin...U_Toys_Hobbies_Model_Kits&hash=item3f02ac95bd
It has a book of quite good drawings. The kit is complete except for screws. I needed to buy the cap headed screws etc separately.
The aluminium and brass pistons and the hot chamber for it come prefab but the rest is all bar stock. I found the brass piston wasn't quite round and it didn't seal well enough in the cylinder that I had made. This meant that the engine wouldn't run. I made a duplicate one out of bronze that sealed better and now it works.
The other modification I made was to the brass stand under the flywheel. The kit comes with a sheet of brass about 1mm thick. The plan tells you to bend this to 90deg to attach it to the base. I stuffed this up so got another piece of flat brass as the vertical part of the stand and screwed a length of ~8mm square brass to the base of it. I then could attach the square brass to the ally plate under the engine.
