Printed the plans off, including the missing pages. making this 1:1 scale as per the plans as I had some 1/4 brass plate just the right size.

A bit of milling, sawing and filing.............

Plans show tapped holes as 2-56 UNC ~ mine are 8BA. Cylinder in cast iron

Hi David, the brass frames look smashing. I made one with aluminium frames in 2x scale - my eyesight couldn't cope with the tiny fixings. I also changed to metric fixings. I built mine as a sort of learning project to give me a focus for trying to learn all the various techniques needed. Seemed to work although my engine shows many of the mistakes I made along the way!

It's all your fault Wheeltapper !! Took my inspiration to make this engine from your post
 
 
and yes at plan scale it is like watchmaking (I guess having never done any) but it is a good way for me to improve my model engineering skills and accuracy having worked in heavy (steam) engineering for the last 30 years, and it means I can buy more workshop miniture tooling !
 
Hugh ~ love the video and really like the "air supply manifold" ~ guess what my next project is when I'm struggling and getting frustrated with 10BA and fancy a rest from the OBG beam?

Sorry about that
 
I thought when I first saw it that it would be a unique build but it seems everyone and his uncle has made one, plan size, twice size ,half size ,one and a half like me.
 
It certainly is a popular model.

Got a little friend to help me keep motivated, seems along time since doing any of the "OldBoatGuy" beam
 
Just one little mistake in the second cut out "bling" ~ oh well hopefully it will blend in with a little riffle file

I must admit, the beam looks a lot better with the recesses in it. I might take mine to bits one day and have a go.

I must say, I managed to build mine without the missing pages by enlarging the plans to full size and measuring straight off them.
 
it seemed to work.
 
I really must try to get a video of mine working.
