I'm always impressed by the people that can take a piece of roundstock and come up with something not round (e.g. the cylinder with the porting face).

hello Mirek,
are the plans you're using for this available somewhere, or are they your own design?

Looks like an interesting build - I'd like to try it.

Hi Mirek, i am very interested in your cylinder making methods, could you please tell me the diameter of the brass bar you started with.
Regards Terry.

Thank you Mirek i am not an experienced engineer like you and do not have the equipment you have, but i have a ML7 Myford lathe and Chester Mill and i am considering having a go as i think the engine is superb.
Regards Terry.

If you are able to solder then you can build up the cylinder quite easily, infact could probably just stick it together with JBWeld which saves a lot of material and milling time, similar sort of thing below
