The secret is in the art work and processing the base image. The actual test piece was the first off the machine today. It was the subsequent 'improvements' that didn't go as well.

What are you thoughts on this sample?

very impressive!
I feel that the "mortar lines" are a bit too deep, but I haven't seen the original! And, if "deep" is required, it's fine; if not, a wipe over with a waterbased filler will make them shallower in short order, or careful pointing would do the same in rather longer but without risking losing the texture in the faces of the stones.
And the potential for moss & general grubbiness is huge.
back to the earlier photo - presumably you would want to take the photos with the sun at a very shallow angle, to highlight the 'umps & 'ollers?

Getting back to pressing commission work, the NER Signal Box is going through its test build.

A bit more done this morning of the test build and the snagging list is getting a longer...

To show the versatility of the laser and how fine it can work with the right tweaking, here is a weighbridge plate designed for 3d printing by Nikki Wilkes and adapted by me for laser engraving. The laser made short work of this taking 12 minutes from start to finish after my setup time in QCAD/CorelDraw17.
The 1947 date is less than 1.5mm high

Phil,
If you come across a rail weighbridge plate I'd be interested.

I have thought about that. Have you got a picture? I'm sure I could run one up quick quickly. Would you want to use my lasercut chairs or do something else?

I've been looking at these just recently.
Old style cast iron plates with provision for rail use seem to be uncommon - here are a few:
Denison (taken over by Avery) - this in an Australian sugar mill. Note the two different length plates for outers and inners, and separate rails - the cast plates would not take the load of a wagon:
I think this is an early Avery bridge, at Greenock Charcoal Works:
And another similar Pooley 30T (location unknown, found on a shotblaster's website so one of their jobs I guess!):
Now here's a rarity - an old cast plate 'bypass' bridge where the weighing rails can be bypassed when not weighing to save wear and tear.
The connections to one set of rails (I guess the non-weighing bypass line) have been removed.
I haven't yet worked out how the mechanism and the two sets of rail supports are laid out.
Again this one is in Australia, at Ballarat - see:
Photograph - Colour - Ballarat Railway Station Weighbridge, 2011 - Victorian Collections
Other than that they seem to be quite dull flat plain steel plate bridges with FB rail bolted on (e.g. NCB installations).
More as and when.

I have a stack of 1950s / 60s /70s plates from old bridges (don't ask...) - they are not so pretty as the earlier cast plates but if you want I can photograph them when I next move them.
I don't charge for brass rubbing
The plates were typically in 6ft -10ft lengths, used in multiple to create whatever length bridge was required.

Here's a link to an early rail wagon bridge:

That would make a great feature on a layout that I’ve never seen modelled. Someone must pick this up and build this.

Hayle Harbour North Quay - from Hayle Wharf.
And another image here:

You could easily adapt your Avery plate for this.

I want to know how to draw that up in Templot

On the subject of Templot, see here for a drawing of a typical track installation:

The link to the 7mm Cadbury layout on RMW is worth following.
This is the drawing for double track - Australian:
