Jo. Did you ever get to make your G30 engine run? If so, how did you do that? I ask as, as well as me, a friend "Down Under" who sent me the plans could not get it to fire either. He had the benefit of build instructions and castings, I did not have any instructions and built it from bar stock not castings.
The design in the videos Achim posted is based on the Barr & Stroud published in SIC. There seem to be a few working examples of the Barr & Stroud on the web.People build what they know, and can get information for. I've spent a lot of time looking for information sleeve valve engines. There simply isn't much in the public domain. It's no surprise there aren't many models built. I have prints for the Barr & Stroud and G30.Other than sealing two rings making a thin sleeve round, what else would be problematic? Which components remain to be made? Do you have sleeve cranks and sleeves? Materials are a concern if there is to be significant power and/or runtime.
As was mentioned, the last issue of SIC has a sleeve valve engine build. Below is the port layout used in most aircraft engines from Sir Harry Ricardo's book The High Speed Internal Combustion Engine.Lohring Miller

Quote from: Laurentic on January 24, 2022, 03:02:48 PMIt is interesting that Ageless engines could not get their 9 cylinder sleeve valve engine to run, but I thought they had got a single cylinder trial version to run......??Chris. Lee at Ageless does not understand why his 14 cylinder (not 9) Hercules look-a-like will not run. He did get the single cylinder test rig to run. There is a video of it running on his website. You may have to dig down to find it.Have you tried a soapy water bubble test, to look for any obvious external air leaks, on your G30 Mike
