I think I would like to build this one.

Re: Lady Anne variation.
ha, by accident I've read yesterday(maybe for the third time, I find it an fascinating design) this topic (and al the related topic like Jane grey,the BIG lady etc), and I also couldn't find the revised dimensions. It seemt to me that te conus from the sparkplug to the combustionchamber is elongated.
Are the inner dimensions of the inlets still 20.5mm?
I just last night calculated about 4 hours to a 20% scaling up of the Lady Jane Gray.
Because the topic was so old, I was planning to contact James or Graham by PM, but because you already did it here, I do it also in this topic u

Re: Lady Anne variation.
For the Snake fuel injector, how thin is the copper pipe? It seems like it would be difficult to get it to ball up on the end to drill the 4 holes.
Have these runs been on gaseous propane?
I read Graham used 1mm stainless and in the beginning James used 0.7 mm.
My local shop has some smaller stock of 314 stainless 0.7mm.
Would you guys recommend something(alloy/thickness) else?
Best Regards,
Cory
(P.S. Graham I tried your email but it bounced back)

Re: Lady Anne variation.
This has Graham mailed to me (I prefer with very old topics to contact the author/builder by pm )
Good luck
I'm also planning to build such an engine, and I think when you're really interested, Graham will send the latest drawings to you.Ensure you have no restrictions between the Propane tank and the injectors.
The fuel pipes are 4mm O.D. thin wall copper made-up as shown in the photographs.
Good luck

Re: Lady Anne variation.
After reading this thread several times over the years, a question surfaces:
James D, what inspired you to add a second intake?

Re: Lady Anne variation.
If the centre of combustion had moved 'south' towards the tailpipe would that give an increase in frequency or is it just likely to be running hotter?
