jukebox Posted December 17, 2012 Share Posted December 17, 2012 Ah, now thats the view you need! If you look closely, the side wall actually projects beyond the "column" towards the bottom of the mouth - although when modelled this may not "look right", so perhaps you could use modeller's licence, and have the toe of the retaining wall end in line with the tunnel mouth edge of the stone column. Let me know if that doesn't make sense and i'll sketch what I am bumbling about... Also, I do agree with Michael on the capping stones - esp. now I can see then from this angle. (Trust me, I'm no engineering genius! But some of this comes from what you can I have talked about before - things "looking right", be it thickness of bridge spans, angles of wall etc... like a lot of what we do, it comes from observing real life buildings and structures and wondering 1/, how they did something and 2/.why they did it the way they did. I explained to my son the other day I could never be an electrcal engineer: if I can't see what is happening, I often struggle to understand it. That makes me a natural as a civil engineer!)

RMweb Premium Physicsman Posted December 17, 2012 Author RMweb Premium Share Posted December 17, 2012 Where does the water go? It certainly makes it down to the formation on the left hand side (through a 90* turn in the wing wall) but the right hand side is a little more difficult to see. Do they just go into culverts heading towards the river bridge seen in the old photos that I linked to about 20 odd pages ago? Thats my guess, as the stream or whatever that is there would probably be the easiest place to get rid of it. Maybe Jeff you could have a 'gusher' coming out of the side of your drop board by the viaduct? That would look quite impressive! Andy G That's a perfectly feasible and brilliant idea - especially as this tunnel mouth is adjacent to the viaduct, with its attendant river. Yes, I'll consider that! Water in a river isn't too bad to model: a material like Woodland Scenics "Realistic Water" - a gel-like substance - is very good. I've never modelled a mini-waterfall before. So? There's always a first time. I had an aversion to scratchbuilding - didn't know what I was missing until I started this layout. Ok, I'm off to do some more ply cutting. Thanks again for the info and some great ideas. Jeff Link to post Share on other sites More sharing options...
RMweb Premium uax6 Posted December 17, 2012 RMweb Premium Share Posted December 17, 2012 Jeff, having just studied your portal photo again, the top parapit wall of the original has quite a curve over the top of the arch, whereas yours is flat. Maybe when you add the stonework you could make the top centre of the parapit wall about 3-4mm taller, with a curve down to the sides? Sorry If I'm being pickky again, feel free to use rule 1 (or as we say on the railway a Form 1 (discaplinary form!)) Andy G Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted December 17, 2012 Author RMweb Premium Share Posted December 17, 2012 Thanks Scott. One reason why I don't want to model the prototype to the n-th degree is because, with limited data via photos, it's easy to "get it wrong". so I'll go with overall trends - so it "looks ok". Please forgive me if I overlook something that's obvious! The shame about this construction is that its location/angle near the viaduct doesn't make it a prominent feature. BUT there are two other tunnel mouths to do... I'll see what I can come up with there ... another S&C with a bit of character. Jeff Link to post Share on other sites More sharing options...

That's an easy thing which I've already incorporated into my plans. No problem Andy - it's good to check things over. Ok, I'm off for now, though I'll check back here in an hour or so.

Andrew P Posted December 17, 2012 Share Posted December 17, 2012 Hi Jeff, 3.51AM and I am up, could not sleep so checking on here and then to look at some N Gauge stock ready for Project Glenfinick. I already have the new Dapol 26 in Green and a Blue one put by, just a couple of 37's a Black 5, B1, and poss a Jubilee for the Rail Tour Specials, Whoopee cant wait to get going. Emjoy you Cricket, never a game I could get into, with silly mid on, that sounds to much like me. I enjoy F1 and I used to do Motorcycle Trials and Motocross in my teens untill I fell off too many times and spent on Sunday afternoon in Reading Hospital after a tumble in practice. all great days. I will be back. Andy. Link to post Share on other sites More sharing options...
RMweb Premium Physicsman Posted December 17, 2012 Author RMweb Premium Share Posted December 17, 2012 Morning Andy. I went "to bed" at 2am, was up at 4am for the cricket, then dozed off. My god, man - you've bought yourself an N gauge fleet already!! Either you're a lottery winner or your wife is very generous!! Time for COFFEE, then more work on the tunnel mouth. I'm going to my dads this week, but I'll be taking all the gear so I can get on with the job. Anyway, more "steps" to cut...another 60 of them.

I'm off to Barbados with that. hehehehe My Wife, Mother, and my FOUR WONDERFULL Stepchildren all know I like MONEY for Christmas and Birthdays. any way it's only the same as you do, a dream list and then sit back and close my eyes, BUT not at 4 in the Morning, ho ho ho How many steps to heaven are you expecting sunshine? I can just picture you and your Dad on Christmas day, you cutting steps and him cutting the Turkey and saying, Come on lad itll be cowd, and you can't eat it with a Stanley Knife., he ho ha ha he he .

RMweb Premium southern42 Posted December 17, 2012 RMweb Premium Share Posted December 17, 2012 Jeff and Andy. Cricket. I only remember playing cricket a few times. The first was one summer when one of the other kid's dad got us sorted on the footy pitch up the road. Another was on the beach on a summer holiday. Then there was the works inter department match some years back when, despite my incompetence, I received a match certificate for performance - my poor bowling got a credible batsman out! Anyway, we won the match but these days I think I'll stick to modelling. So, what's the loco, jukebox? Is that the one going north? Polly Link to post Share on other sites More sharing options...

A tenner!! it was only a fiver last time, I think you must be saving up for that loco you want LoL. Just a quick visit this as I have a few things to sort out on the domestic front before normal service resumes. The tunnel portal is looking great though Jeff, especially those steps.

RMweb Premium Physicsman Posted December 17, 2012 Author RMweb Premium Share Posted December 17, 2012 Update: I've fitted the drainage "steps" to each wing of the portal. The wings have been thickened up and a cant put onto the inside faces. The PVA is currently drying. The glue should have set by 10pm, so I'll post a couple of photos then. There's an eerie calm about the forum today. Maybe some people are exhausted after having a good "Hornby revelation froth". The P2 and Duke of Gloucester look nice, but I've plenty to keep me going in the meantime. Now where's that rogue Andy P with his plan to buy out the entire N gauge stock of Hattons?!

Jeff Im ear guv, just looking at those steps, Whats this about me buying up all Hattons stock of N, I was only dreaming . I will have to see how much money Santa gives me at crimbo, AND HOW MUCH OF IT I DON'T HAVE TO SEND ON OTHER FOLK, ho ho ho, me mean no , just a little tight acording to my good lady. BTW I don't know if you know but ther is a real Andy P on the web, that's why I couldn't use it. I bet he gets really worried when he sees he is buying N, O and OO, next it will be the NARROW STUFF.
