Knadgerhill - the long slog

Making a curved tunnel roof from mountboard

 and cereal card

Lining it with Scalescenes brick paper using a unique/hand crafted/artisan template 

and adding stone voissiors (?)

There are a few gaps that need filling, and the whole thing is going to get so thoroughly weathered that the brickwork will be almost invisible, but it has been satisfying (and time consuming) to make.

Attempt 1 at using (dry) weathering powder (with a paintbrush). Conclusion: not very good. Cotton ball might do better.

This is turning into a far more 'occasional' series of updates than I hoped.

It has been back in the garage working on the final baseboards when I could put up with the temperatures recently. This board has a unique issue in the form of 3 points where  the track leaves the board at a very much not 90 degree angle. I am addressing this  by adding triangular wedges outside the board. It has been a learning journey. Version 1 was a simple, solid triangle, to be attached using the two slots, glue and a couple of horizontal screws.

I decided this may have something to recommend in potentially being able to sacrifice the wedge if damaged without destroying the whole board, but not sure about the strength of the join. So for version 2 I cut the main board side down so that the wedge rests firmly on the board side, to be held in place by glue and horizontal screws. Better.

Version 3 is more integral to the main baseboard, with the edge strips continuing into the baseboard and attached to deeper supports.

I feel that version 3 is the better choice, and more likely to retain vertical alignment with the mating board. So version 1 is getting amended to reflect what I've learnt.

PS. I cannot explain where the underlining in the above post came from.

Next in the occasional updates...

For a while the garage was habitable. Then around Easter the night temperatures dropped and I had had enough and retreated indoors to play with card.

 

Here is the second half of the urban viaduct. I always feel less like a planned engineer, more of a bodger, adapting things as I go along when the first idea doesn't quite fit. Here I am using an amended way of sticking the arch skin to the side walls after I felt the original technique was too weak. I just hope the width is the same as the first half.

View from above gives away my card source. Other boxes may be equally tasty, tasty, very very tasty.

One problem I have had is the join between the viaduct arch barrel and the wall.

 

 

I've tried a few different methods

 

 

More to follow.

Phew, just scraped in less than a year since my previous post. Various excuses, family, work, exercise. Scouting means that I have two hobbies that expand to fill the time available, as a result trains barely got touched from summer to Christmas. Back doing bits and pieces, revisiting boards, building the remaining 2, but keep jumping from task to task so everything is permanently half-done.  When I can remember my password on a device capable of taking photos I will start posting visual updates again.

So I have been pottering away with the usual slow progress, but have not bothered adding any updates for a while as nothing seems to get completed. Tonight is tunnel design, and I seem to have got about the right combination of curves. Clearance is not huge so I will probably expand everything by a few mm. The second photo is the Engineer's Toolkit - from L to right the source of the 3 curves involved.
