Hot air engine

Greetings, I found this video of a hot air engine and I attempting to reproduce it. I have all the materials to start. The main problem is I do not know how to cut a 9 inch large diameter hole in 3/16 or 1/4 plate steel. What is the best tooling and method for the procedure? Thank you for any info received.

A good quality jig saw, the best quality keyhole saw blade and  some patience. My 2 Cent.
Or a good contact to a local water jet, laser or plasma cutting company.
Kind Regards

The old fashioned way, chain drill, saw, file (this may be MEM but we are still allowed to work with our hands ) :)

Hi, thanks for the info. I was thinking about it after I made the post and I may be able to fabricate a simple rotatory jig and use me mill. It is nice to have options, thanks again.

If I can get the project to work, I plan to use it to drive a permanent magnet alternator.
