Especially as I've just discovered the ply fascia is only 3mm. Oh dear, I wonder if it will drop off in the next 200 years?!! J. I'm sure that 1mm will make a great deal of difference. 1 Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted May 10, 2021 Author RMweb Premium Share Posted May 10, 2021 I wasn't entirely happy with the occupation bridge I built yesterday. So I've built another one. Pics later. J. 2 Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted May 10, 2021 Author RMweb Premium Share Posted May 10, 2021 The proportions of the bridge didn't look quite right, and I thought the centre piers were just a little bit too close to the track (about 6mm for each pier). So I went back to my 3mm ply sheet and 12mm birch ply and made another. The pics appear to show 2 different ground colours. Pics 1 and 3 were with the DSLR, the rest off the phone.

Thanks for that, Jonathan. I drew up my initial plan about 2 years ago, using images of the structure at Kirkby Stephen. I went back to about a dozen pics last night and decided I could stretch the central width a little - so I now have it at 27 feet (108mm) rather than the 24' (96mm) previously. Whatever the "true" value, I think it just looks better. I also made some detailed measurements of the central arch, and the curve is a bit different to yesterday's. Both changes make it easier for locos to get round the point where the curve is the tightest on the layout (30" for about 2 yards) . Jeff 3 Link to post Share on other sites More sharing options...

The situation needed to be resolved, whatever the track radius. It's just pure coincidence that I'm using the bridge at the point of tightest radius. Anywhere else would have been around the 36" (91cm) mark - or larger. And yes, I'd worry about a 9F, Brit or class 40 struggling round there. Hopefully not!

RMweb Premium Popular Post Physicsman Posted May 11, 2021 Author RMweb Premium Popular Post Share Posted May 11, 2021 An update on today's proceedings - work on the Occupation Bridge... Pics 1 to 4 show the fitting of the brick arch liners. Ply supports were fitted to the bottom of the road deck and the Slaters brick sheet cut to size and glued in place with evo stik. Pics 5 and 6 show the beginnings of work on the fascias. The brick plastikard is only 20thou (0.5mm) and needs "packing out" with cut-to-shape 40thou as the arch rings will be made from 80thou, and mustn't stand too proud. Both front and back faces are at this stage. Pic 7 shows the (strange, partially covered) structure in position. Further progress tomorrow.

RMweb Premium Popular Post Physicsman Posted May 12, 2021 Author RMweb Premium Popular Post Share Posted May 12, 2021 A few pics showing today's efforts, so far. I've spent around 3 hours cutting arch rings out of plastikard sheet. Always fiddly, but the tedious bit was scribing grooves into the ring surface to represent layers of brick. It's much easier fitting bricks and stones onto a ring if you can do it individually, but in this case the bricks are far too small. Only one side done so far, so I'll have the joy of the other side tomorrow. Maybe read a popular bestseller tonight....The Joy of Sides. Sorry, couldn't resist. A demolition job was done on the cutting areas in proximity to the bridge to facilitate access for the farm animals - and future wall positions sorted. Image 1 is a reminder of what the bridge should look like. Plenty of weathering, painting and general grotting-up to go yet! Jeff 19 3 Link to post Share on other sites More sharing options...
RMweb Premium John Besley Posted May 12, 2021 RMweb Premium Share Posted May 12, 2021 Just close your eyes... It's a warm summer's day in late '67 in the fells.. the air is full of the sound of insects buzzing, in the distance sheep are grazing and the sound of a skylark is carried as it climbs higher and higher before dropping back to ground... Faintly at first carried on the breeze can be heard a loco working hard, the sound fades and comes back stronger as the train approaches... suddenly bursting into view under the bridge comes a Brittania with a long train of boxvans, she surges past with the Van's rattling behind brought up by the guards van... the Brit' climbing hard heading to Carlisle.... the sound fades leaving just the fragrance of coal smoke and steam oil... The sheep carry on grazing, and the skylark carries on with its song as the silence of the fells return... 7 3 Link to post Share on other sites More sharing options...

RMweb Premium Physicsman Posted May 12, 2021 Author RMweb Premium Share Posted May 12, 2021 I remember the film very well - Stanley Baker was always one of my favourite actors. If I get chance tomorrow - in between fiddling with plastikard on the bridge arches - I may be able to put something in place for those British troopers to hide behind.... We will see. If Jonathan looks in, he'll accuse me of being a "tease" again! Jeff 1 2 Link to post Share on other sites More sharing options...

RMweb Gold Donw Posted May 14, 2021 RMweb Gold Share Posted May 14, 2021 Well we have been a bit lacking on the sound of trains this year and the number of skylarks seems to be less. The crop in the fields behind us is corn this year perhaps not to their taste. Not bad when it is your garden and maybe I might be able to lay track this year for the live steamers.

RMweb Premium Physicsman Posted May 15, 2021 Author RMweb Premium Share Posted May 15, 2021 (edited) Well spotted, David. Building walls is a slow process - I think I averaged about 8cm an hour - a cm has about 30 stones in it. KL2 ended up with about 25 metres of walling and I salvaged around 10 metres during the demolition process - all straight pieces from relatively level terrain. I've managed to use around 2 metres over the last day or so, matching and linking some sections together. Those 2 metres have already saved me about 30 hours work. However, I'll have to build all the walling that goes up and down slopes. I made a batch of DAS strips last night, so - if they are dry - I can do some building later. Work continues on the bridge. It has all 6 arch rings and I'll get back to that shortly. Jeff Edited May 15, 2021 by Physicsman 8 1 Link to post Share on other sites More sharing options...
