I cannot appear to "nail" wooden chocks through steel plates, although I can still place some.
Some Showmans engines were fitted with a basic pole crane for erecting rides. Could be part of that.The agricultural engine would not have the big generator/dynamo mounted ahead of the chimney, nor indeed the rather fancy barleytwist poles, but I guess they’d come off with the roof.
I’m a little puzzled by the thing at the back over the coal space?
there are some prototype photos in Brian’s “Tim Mills’ Photos” thread.
Use or make or buy a suitable sized hole punch and make your own discs . Buy some 5" or 6" sticky back discs of the grit that you want then just punch out your discs. An automotive supply shop should be able to help with the discs , they may even have a mixed pack of grit types .The discs I am using are sanding discs not cut-off discs. They are discs of aluminium oxide paper with a self-adhesive backing, stuck onto to a pliable mount made from some kind of synthetic rubber.

On the left is the one I have been using. It is nearly worn out and I cannot find the spare discs. On the right is a smaller disc with its mount.

The smaller version is from this "Rotary Tool Accessory Set" by Parkside. I seem to remember this set cost less than £10, so about 3p per item!
I am holding the mini-drill in my dominant hand and the brass part in my other hand. You see the cusp disappear before your eyes. The drill speed is I guess around 12,000 rpm.
I don't think there is any great risk of "digging in", but you can remove too much material if you linger too long. I have done this (just once!) and it shows up in one of my photos if you look carefully.

I've got a feeling, an amber light shows for three seconds at UK traffic lights? Re-watching the video, I think he started the stopping process immediately the lights went amber - and it took him three and a half seconds to come to a halt. It's always worthwhile to understand how other people's road vehicles behave, I know this from the way agricultural tractors do steering.I see he SPADed…
I now have a 105 gram wagon carrying 75 grams of lead; and the length over headstocks is 180 mm. Just what the guidelines for weighting say.
The springs are a tiny bit askew but their arms have straightened up on the model.



So I now have a 165 gram wagon instead of a 180 gram one, to make the springs work properly. I don't understand why I have had to do this.
Possibly what is confusing you is that you have one fixed axle.

A while ago, I established there are no kits in 7mm scale for a ploughing engine, and probably only one kit for an agricultural engine. This being an Aveling Porter from Duncan Models. On the bright side, Corgi do a 1:50 scale showman's engine and one of these has just arrived.
. . . a series of kits in 1:43 scale were produced for various traction engines, agricultural machines etc
the thresher is to tall approx 90mm from rail tops, maybe with wheels removed perhapsThank you Martin. The Burrell traction engine and the Ransomes threshing machine look particularly suitable for my layout. I can see they turn up on eBay from time to time . . . I will keep an eye out for them.
