Double Diagonal Engine - errata?

[8thscale]

Maybe I am wrong but I found the following...

Detail 8: flywheel
pg 30 "drilled the 18 (dia)10mm holes" perhaps this should be (dia)6mm?
this produces 4mm wide spokes (otherwise they are 0mm wide!)

Detail 10: crosshead
There should be a radius (R2 ?) on the upper drawing.
There is no radius on the drawing to the lower right.

Anybody else?

Hello Dave

I are absolutly right, I put an error in the text as I read my drawing as Ø10 but it is Ø6 holes divided in a R10 circle at center (and R24.5 at the outer circle)

About the crosshead I see now that I have been combining 1.st and 3.rd angle projection in that on - and no I was not trying to see you all were awake

Sorry for any trouble you might have due to these errors

Thank you Mogens.

I am currently building this as a 3D CAD excercise.
I have enjoyed your article as the mill work was done on a lathe.

The diagonal steam engine is a very interesting arrangement, and the article is a nice project. There is an excellent photo of a prototype engine on the web at
