Building Ginnerbeck viaduct for the Rylston Light Final Part.
The last instalment opened with the reveal of whether the newly assembled viaduct would fall apart on its first lift. Spoiler: It didn’t.
This instalment opens with whether I survived after the debacle of the expanding foam in the dining room. Spoiler: I did
At this stage the major part of the build was complete. The final result of the expanding foam was disappointing in terms noise abatement but there was a separate benefit of doing it. The overall rigidity of the piers was improved and I would do this again.
The joins between the arch-side panels were adequately hidden by the triangular block strips, but that portion of the wall above track level was still visible as a plain butt joint with non-continuous stone courses. These needed to be blended in with forming stone courses across the joints using U-pol filler. The following (poor) photo shows the effect achieved.

I felt that the triangular strips were a little too visually prominent. I had an old Siligum mould for a tie-rod anchor-plate that I had made for the buttresses of Lygibeck viaduct some time ago. I cast 16 anchor plates figuring that they would shrink the impact of the triangular strips.

These were fitted to each side panel with dollops of U-pol. I filled any remaining gaps with U-pol.
Side note: over half a 3L tin of U-pol was used just in assembling and filling the viaduct.
Still another hour before the local forecast predicted rain, so into the garden for some undercoat. I’m always amazed how a unifying coat of one colour dramatically pulls a project together on a new level. It took 3 large rattle cans of plastic primer, and then a light spritz with the very little flat khaki I had in stock before the final photos for this opus.

Now if you have followed this somewhat detailed account to the end then I thank you. Obviously I need to paint the viaduct properly and weather it, then there is the no small matter of building the miniscape into which it sits. I will post a final picture when it is weathered but there will be some delay before I can finish the paint job . . .
I have to de-goop the dining room first.
Hope you all enjoyed the ride. Andy
