    Obviously some of you guys have never made it plain to the partners in your lives just where they stood in the pecking order. Before I got married, I took The Boss on a Portrush Flyer, then didn't sit with her so that I could get a milepost seat. The honeymoon was two weeks behind the Iron Curtain bashing very obscure steam, followed by a week in Vienna so that she could visit her many friends there (and I could bash Austrian steam while she was with them). It wasn't my fault if she hadn't got the message by then? Getting back to paying for the locos and the stuff I'm producing this year (just a hint, you realise!). The Church had a solution - join the Total Abstinence guys (The Pioneers?) or become a Methodist! Either way, NOT drinking 3/4 pints a week will pay for everything that comes out this year! Just remembered, Lent's starting - give up booze for Lent and that'd pay for an A Class, at least. Get your partner to give up chocolate for Lent and you can have a rake of Ferts as well? No charge for the advice!

    Hi Dave This in a Gauge N baseboard module which is the same construction design as the one above except;- it was constructed in cheepo 6mm ply with the 40mm insulation for the deck but has no laminated internal frame like the one above. The flat gusset piece in the corners are glued to the frame and to the underside of the insulation, the insulation is glued in with 'No More Nails' glue on the 40mm edge which makes the board fairly rigid in all directions, each module weighs in at 2lb. These boards fit end to end. The end plates are doubled up with a rectangular slot to take the support system, fixing two boards together involves sandwiching the support leg between the two boards in the slot and using a C clamp to hold in place. These units can go on a table or use their own support system! but I found it was to light and liable to be knocked over so had to add Lidl lifting weights to the leg bases. Eoin

    Hi WRENNEIRE, I'm new here and have spent hours reading through this fascinating thread. Not least it brought back memories of pipe smoke on Sunday mornings in Monk Place and of the Southern Model Railway shop as I remember it in a basement in Leeson St. Anyway my question is, would you consider it appropriate to include here items not specifically produced for or aimed at the Irish market but regardless may well be appropriate for use by Irish Railway modelers. A particular example I have in mind is the class A Esso 4 wheel tank wagons produced by Heljan, their catalog no. 1153, albeit the running numbers may not be correct. There is also a weathered version no longer available. Thank you

    I am thinking about doing Cobh Station, in a sort of Generic way so that I could run steam or diesel in it and it would still look ok. The buildings would all be correct but in a hypathetical era... if that makes any sense 🤔 for example, there was a fine water tower/ coal shed and a turntable, long gone now but I would still include them even though on the odd day, there might be a DMU motoring past .

    Oh thats an impressive baseboard. Strong as an Ox for N and yet weights nothing. There's always more than one good way of peeling an orange! PS. Sealing the plywood with a good sealer/primer coat of paint IMHO can do more to aid moisture resistance and warp stability than anything else, especially the underside of the boards as well as the topside.

    Noel. The most problematic construction, in my experience , is dissimilar woods , In far too many cases Ive seen the 2"x1" being stabilised by the ply and not the other way round. Then to compensate for what is a fundamentally bad approach , the thickness of everything is beefed up, ( and gets corresponding heavy ) While this " solves " the issue , its really a poor way to go about it . This is even truer today , as commonly available deal is often forced growth, poorly dried and inaccurate. Th timber and ply commonly available in local builders providers is invariably rubbish and is the cheapest around type of stuff as most purchasers dont care about warpage or humidity issues That method of construction largely evolved because it was what people could easily get in their local hardware store, getting good quality ply is still very difficult to this day and requires use of a specialist provider , glue and tape construction is not common to the average DIYer or railway modeller, ( nor is laminating or other specialist methodologies ) hence we have the Deal and ply construction Its easy to make something strong and heavy , its easy to make something light and weak , the trick is strong and light. Note that many construction systems will allow you to " walk on the boards", the issue is what is the resulting deflection !, and more importantly over time how they react to moisture and changes in humidity and temperature . Everard Junction has an interesting discussion on what went wrong with his baseboards over the years. IN my opinion , ply on ply construction ( however you approach the particular construction ) using good quality ply is the best approach while still avoiding terribly exotic materials or advanced construction techniques . Laser cut , all ply boards ( which we tested for the O gauge and discounted ) makes exceptionally light and strong baseboards, but requires all the baseboards to be accurately designed in advance. The use of interlocking tabs in laser cut , makes the joins very strong and in fact the test boards we made up ( which can be seen in the club) didnt need tape and glue. There is a multitude of baseboard methods, and many will " suffice " , some are " good" and a few are class leading. Again it all depends on what you want as the design goal, cost, weight , strength etc This leaves aside discussion on other forms of compressed sheet , other then ply as, thats another ball game entirely , or composite sandwich foam types ( which I did consider for the O gauge and still feel has promise Dave

    Now, Leslie, we can all do with a good bit of advice from time to time, especially in the realm of those female women of the opposite sex. We could all even become Methodists, if it meant cash for a new loco. But ye can't be serious about giving up three - or even FOUR - pints! That's a bridge too far....

    As the person who designed the O gauge ply and glue construction , it’s true the method works best with fibreglass resin and fibreglass tape However our experience with the O gauge is that while the main baseboards are resin and are effectively bomb proof , the pva baseboards are surviving the rough and tumble more then adequately the sides are not designed for lateral loading, their primary purpose is to stress the top and keep it flat the end cheeks are 15mm ply ( all ply is high grade birch ply , either MR glue or WBP glue , I would reccomend staying well away from cheaper grades of ply ) The biggest stress area , can come on the end cheeks as they are dismantled , any vertical movement with the steel dowels still engaged effectively causes one board to act as a lever on the end check joints . Roughly abused the pva units will fracture , however interesting the hot glue is so strongly bonded it usually rips the surface lamination fron the ply in the process. Hence in the pva /hot glue variant a lot of strength comes from the hot glue it would seem in the original fibreglass design ( my own layout is all resin ) there is appreciable additional strength from the fibreglass , the ply will completely fail before the joint releases. The pva variant is a compromise albeit a good one and it’s difficult to badly apply pva whereas fibreglass laminating resin needs some experience and a room temperature over 15 degrees C , not to mention the all persuasive styrene monomer smell that lingers and really requires breathing filters having said that I glassed mine in my back spare bedroom , during a winter !! ( I have a tolerant wife ) i put one test board in my outside steel garden shed for 6 months of the winter braced at an odd angle , no distortion or delamination was observed the primary advantagous of the method are (1) exceptional ridigity combined with low weight due to the use of 6mm ply yet fast construction , an experienced person can assemble a 5, x 2.5’ in 40 minutes fully glassed (3) if diagonally braced , good resistance to torsional stress , tests show on a 5’ X 2.5’ board raising the opposite corner 4mm will lift the diagonal opppsing corner (4) the use of computerised cuting delivers dimensional accuracies without resorting to fully designed up baseboards like laser cut (5) no on site specialist equipment is needed nor any carpentry skills other then a couple of squares and a few clamps , a decent chop saw is useful but not essential (6) no screws or nails used in the main body of the board (7) the hot glue method means the board is instantly transportable and can be glassed in another location , brought home in a car etc (8) the design is such that variations can be accomdated without recourse to more computerised cutting ( ie curved baseboards ) , lift sections (9) the construction method can produce open frame variants (10 ) did I say it’s strong , a 5’ by 2.5’ supported just on its bare ends exhibits 2mm sag when a 10 stone man sat in the middle !! , yet such a baseboard can be comfortable carried by one person There are some disadvantages (1) the use of legs fixed to the sides is not really supported , as the 6mm ( 120 mm deep ) sides are not designed to handle significant horizontal loading ( as opppsed to vertical loading ) the design is optimised for self standing trestles (2) the same issues arises with structures that leverage the side frames , like lighting supports and pelmets , these really need to be free standing from the floor even if tied to the sides for stability (3) not everyone is comfortable with polyester laminating resin The design was subjected to some limited finite stress analysis in fusion 360 . If anyone would like to discuss the construction method , the O gauge layout will be at Easter WMRC , Belfast , august 2019 and Dublin ( Blackrock 2019) dave

    I would suggest you consider extruded polystyrene rather then expanded Also I would be interested to see how the torsional rigidity works out . I found that without diagonal cross bracing , the ply construction was rigid both across and along the horizontal axis , but exhibited considerable diagonal movement , now this isnt such an issue where boards are levelled before the layout is used , but we did add diagonals to our O gauge boards ( which are a good bit bigger the 1000x 500) and to all other ply and tape boards we have subsequently made up ( Over 40 at the last count ) The layout is so rigid when erected that the certain mal adjusted trestles often don't contact the floor , rather then the layout sagging I had considered a extruded styrene base , and also experimented with a lamination of ply/extruded styrene /ply using 3mm ply and 100mm extruded XPS300 , It has much promise , but really needs a vacuum bag , which I dont have . But this type of composite construction doesnt even need side supports for a frame ( other then for cosmetic reasons and joining boards together ) ) I would like to see your boards once they are finished Dave

    The door panels in the ferts were a sort of very heavy plywood. Whatever was in the fertiliser didn't seem to cause any unusual amount of corrosion on the metal parts - I saw them close up all the time. The plywood tended to get quite weatherbeaten towards the end, and I saw a few unpainted panels a couple of times. Livery note, now that I think of it: pre-1987 they carried the CIE roundel, originally on the 2nd door along, looking side on. Towards 1987 doors were getting mixed up and while most remained as described, occasional variations became more common as door were replaced in different positions. On at least one occasion I saw one with two logos, on the 2nd & 3rd doors (beside one another). Naturally, logos were applied in white like on all CIE stock, but if modelling with logos in different positions, or none at all, as also happened, heavy weathering to a "brake-dusted" shade of "off"-white becomes obligatory. As with most types of wagons, after IE came along in 1987, no logos were applied at all.

    I would say however that the method is not suitable for cheap Malaysian ply , my experience with it suggests the layers are not well bonded , and the surface tends to be more dense and less absorbent then birch ply.

    Wow fabulous live scenes. You can just imagine all the industrial noises, clanking, banging, flange squeal, horns, station announcements and the back ground murmur of LPPs chattering on the platforms, a group of nuns in full habit floating gracefully down the platform as if they were on castor wheels, a late student running down the platform in a total flap pushing their full size bicycle, as a guard blows his whistle, prefacing the build up of air in the door closing system and brake system, the loco horn toots, will she make it, will she manage to get the bike on to a standard open coach that has no bike racks, folks on the footbridge cheering her on with encouragement, the kindly guard delays waving the green flag at the driver 200m away, she leaps on, drags the bike on, clunking and banging it as she get clogged in the corridor with American tourists and their King Kong sized luggage. Grid lock, but the door closes, the train ever so quietly start to inch forward as the loco engines 200m away notch up on the launch pad, echoing tumultuously off the station roof as, relief on the students face, she has 3hours to find a seat and plan her route back to Heuston from Claremorris to get the cork train she though she was on. The bike was smiling though on route to the Atlantic greenways. Seriously Noel, those layout scenes are alive with busy plausible activity. Top class. 👍 best IE/IR layout that never ceases to entertain.

    We kick off the March gallery with: Saturday 2nd March 2019: Dublin - Cork services were suspended between Charleville and Cork on this day for panel relaying around the 133 milepost. Mallow passengers were bused to/fro, Charleville while Cork passengers were bused to/from Thurles. Click https://goo.gl/9xAEJM to view.
