Mamod firebox assy and lorry chassis. All rolls etc are scratchbuilt 2.5 inch front and 3 inch diameter rear from 1l4 inch wall aluminium tube. Disc on rear roll is the handbrake drum.
That is going to be a BEAUTY.

Agreed!

Love the steering on that one
that's clean ,long and beautiful I'm glad I opened this this thread 👍
That's an impressive build.
Marvelous steering. I am surprised that I haven’t seen that in practice on big steamers. Very clever.
Where did you get a ready supply of chain?
That is shaping up into an awesome build.
Great work!

The steering, bit of a challenge, is as per full size. If you google Robey Tandem Roller you should get full size machines.
The chain is stainless from Meccano Spares in uk --

Thanks to all for the favorable comments.
I googled as you said. Wow!
On the to do list for visiting the UK: go to a vintage steam event! So many cool machines and it's neat time see the different manufacturing.
That is really well done - a very nice piece of craftsmanship!
Good looking project, hex head bolts in frame are a nice touch, have you checked the gearing, from my experience with TE's it may have to be geared down a bit more.
The RPM's are pretty high on the Mamod oscillators, so for what it is worth I find a 20:1 reduction is about right for a realistic speed on the TE's, you are working with smaller diameter driving wheels so that will have to be taken into consideration.

I had overlooked this and it is now an area of concern but well pleased you mention it.
I will try it now but suspect you will be proved right.
If so, as I want to complete my 4 inch before I pop my clogs, I shall have to find it a new home.
You were right, gearing far too high, so good it was mentioned at this stage.
