A point worth mentioning is that I believe that when Jason converted his drawings to metric the engine came out slightly bigger than the original and so suitable commercially available flywheels as noted in his build log are available.
I found the drawings easy to follow and there were no errors (that I found, anyway), also Jason's build log on here will help if you need a little guidance.
I would encourage you to give it a go.

Hi

Thanks for the replies, I've had another look at the drawings I bought and yes they are imperial intended for castings. I hadn't thought much more about it till seeing Jims engine running but now I have a tad more experience I'd quite like to have a go at making a metric barstock version.

Jason, are the drawings online for anyone to see ?

Thanks
Peter

See Jason's build log in Engines/your own design/Jowett Mk 11 Poppet Valve Steam Engine, currently on page 3 with the last post dated Sept 2016.  (I tried to post a link but failed miserably  :old: )
The build log has each drawing attached to the posting describing the manufacture of the component.

Peter, its also available here as well as ME forum, drawings can be downloaded from the links to Dropbox in ME or just copy the pdfs from the site below

It would be quite easy to scale it back down by letting 1mm = 1/32" and then you could use Stuart 10V/H flywheels or if a glutten for punishment do asI did and also make a mini one by halving my sizes.

That sounds suitably industrial. Great work.
Don't confuse activity with progress
