6” aveling Porter roller drawings ???

[The Pirate]

I wouldn't bother with the Haining designs - like all his stuff - very vague and full of mistakes.
Use full size and scale down.
Alan Davenport, pattern maker has built a 6" Aveling roller - the later pattern AD I think, single, slide valve. Not sure if it's quite finished, but nearly.

That is one of the best models I have seen in a very long time. Not forgetting a certain ploughing engine the other side of the world.
