Three Stirling engine plans with complete part drawings (CNC & glass syringe needed)

There are three Stirling engine plans with complete part drawings on a website named "Stirling Engine Home Page".
This site is made by Dr. Koichi Hirata/平田 宏一, he works for National Maritime Research Institute of Japan.
The last update of this site was in 2002.09 and luckily this site is still alive.
Here's the link to its English version:

There are three building plans I want to share with you guys.
All of them have detailed part drawings, including parameters and materials of each part.
You can make them with CNC and glass syringes.
I attached a small portion of these drawings and photos in this post.

1. LSE-01, a basic Stirling engine which was used in a course in Saitama University/埼玉大学.
http://www.bekkoame.ne.jp/~khirata/english/mk_l01.htm
Under "More Information" banner, there are links to drawings and assembly guide.
To see part drawing for each part, go to " Assembly Drawing of LSE-01 (1) " and there are hyper-links to each drawing.

2. ESE-03, a simplified engine model which boasts of a short assembly time.
http://www.bekkoame.ne.jp/~khirata/english/mk_t03.htm
I suppose this model will have performance similar to educational models on the market. 3. A small rotary Stirling engine
http://www.bekkoame.ne.jp/~khirata/english/mk_rot.htm
All parts drawings are listed in this page and you can get full-size picture by clicking on them.
Rotary displacer Stirling engines are quite rare.
Both footage videos and research papers are not readily available.
So I think this would be valuable for those who want to build one themselves.
I still do not fully understand how they work and what are their advantages.


Dr. Hirata even offered instructions on how to buy and cut glass syringes:

There are also some other valuable resource on this site.
A complete tutorial of Schmidt theory: http://www.bekkoame.ne.jp/~khirata/acad ... chmidt.htm
A simple performance prediction calculator: http://www.bekkoame.ne.jp/~khirata/acad ... implee.htm

As I previously mentioned, this site is very old(20+ Years !!!).
Some of the links are broken and that ESE-10 Stirling engine model was never fully documented.
If you are interested in contents of this site, I recommend saving this site as local file in your computer.

Downloads from that site were hosted on Yahoo and are no longer available there, but if the site URL's are browsed using the Wayback Internet Archive the zip files can still be downloaded from there.

Thank you Tom.
I have noticed many missing files in that ZIP file list.
I'll use Wayback Machine to discover some other sites that I previously considered lost forever.

Here are some questions I want to ask people who had experience in CNC or Lathe:

1.How much does it cost to make parts for each model?

2.Are these drawings complete enough to make engines shown in the pictures?
(I am sorry that I lack basic knowledge in metalworking...)

3.Are these parts difficult to make?
