Horsetan Posted June 24, 2014 Share Posted June 24, 2014 ....Have decided to install a suspended ceiling over the whole railway room to reduce the dust filtering from the concrete ceiling - this is going to be 'interesting' - 'sky hooks' anyone Hopefully it won't collapse later under the weight of the dust Link to post Share on other sites More sharing options...
RMweb Premium jamie92208 Posted June 24, 2014 RMweb Premium Share Posted June 24, 2014 Hi, Gary The ceiling has been painted, but the dust is definitely from the concrete ceiling. The ceiling is beam and block with the living accommodation above there is always going to be some slight movement due to temperature and loading changes The incoming ventilation air is filtered, and even with the vents closed there is still an amount of gritty dust accumulated Ron One idea for the ceiling might be to use floor paint on it. Concrete always seesm to produce dust, whether at the bottom of the room or the top and I know that a good thick floor paint stopped a lot of dust in the garage where we restored a horse tram.

Jamie Hi, Jamie The concrete under surface is sealed by paint, but the vertical mating joints between the blocks and the beams would be better sealed, as it appears this is where the dust is coming from. Sealing all the joints is impractical Ron Link to post Share on other sites More sharing options...
N15class Posted June 24, 2014 Share Posted June 24, 2014 (edited) Hi, Gary The ceiling has been painted, but the dust is definitely from the concrete ceiling.

When we were paint spraying it was better to suck the air in from outside through filters. This pressurises the room slightly and all the dust goes out through the cracks not sucked in.

unclebobkt Posted June 25, 2014 Share Posted June 25, 2014 Have decided to install a suspended ceiling over the whole railway room to reduce the dust filtering from the concrete ceiling - this is going to be 'interesting' - 'sky hooks' anyone Ron., Surely suspended ceilings, and their installation, are nothing new, are they? Were I considering such a problem as excessive dust from the original ceiling then I might want to install a couple of extractor fans in an exterior wall, and an adjustable damper in the suspended ceiling at the end/side remote from the extractors, so that there is a slightly NEGATIVE air-pressure between the original ceiling and the suspended ceiling. Adjusting the damper will ensure an OUTGOING airflow through the extractors, (wch., of course, will need cleaning from, time to time.), and this might handle the problem of the original ceiling's shedding dust. But I'm sure that, as the man on the spot, you'll devise a better and a simpler solution. Link to post Share on other sites More sharing options...

RMweb Premium PaternosterRow Posted June 25, 2014 RMweb Premium Share Posted June 25, 2014 'Sky Hooks' - now that rings a bell. I didn't half feel stupid when going into the foreman's office asking for them one day! Almost as stupid as the 'long wait' I had outside the works office on my second day at work. Do they still play the newbies up like that anymore? Love these layout progress shots Ron. Keep them comming. Fabulous rate of work and nice to see the speed is no barrier to perfection either.

Ron Heggs Posted June 27, 2014 Author Share Posted June 27, 2014 As a great deal of printed brickwork was/is needed for the viaducts, I ordered new colour ink cartridges from Amazon.es. Hey presto, the yellow ink was delivered yesterday, the cyan ink is promised for today by the courier, and the magenta is on extended delivery ... and guess what - the cyan has just run out - now await the sound of a diesel engine struggling uphill to our villa Luckily, magenta and black are all ok for now Pictures of progress on the viaduct tonight Ron 2 Link to post Share on other sites More sharing options...
Popular Post Ron Heggs Posted June 27, 2014 Author Popular Post Share Posted June 27, 2014 A little progress on the CLC viaduct - The inner viaduct arch walls will be fitted when all the wiring for the trackwork has been routed through to the underside of the baseboard. Track components await in the hidden blue box Awaiting the additional brickwork prints for the upper wall sections. Landscaping will take care of the lower level terrain The camera is standing where the loco depot/shed will be - in lieu of the track to/from Deansgate/Oxford Road/Piccadilly. The MSJ&AR track under the Cornbrook Viaduct bridge #1 runs towards Seedley/Salford. On this layout it will be towards the Carriage Sidings. The MSJ&AR track to Altrincham runs to the left over the 'to be completed' bridge Ply sleepering awaits on the track base Multiple crossovers on the approach track. The trackwork for this was built back in 2008, and will relaid in its proper location 27 Link to post Share on other sites More sharing options...

Ron Heggs Posted June 28, 2014 Author Share Posted June 28, 2014 The whole layout is now covered with thin plastic sheeting whilst the first section (30m2) of suspended ceiling is being fixed - definitely no pictures of me stretching over the layout, one foot on ladder and one foot in space with masonry drill in hand - isn't DIY great The cyan ink hasn't turned up - if it doesn't get delivered on Monday, may have to drive to nearest outlet some 30 minutes away, and pay over the odds Ron Link to post Share on other sites More sharing options...
Phil Howe Posted June 28, 2014 Share Posted June 28, 2014 stretching over the layout, one foot on ladder and one foot in space with masonry drill in hand I don't think I could watch that, sounds like the ultimate load test waiting to happen!

sir douglas Posted June 29, 2014 Share Posted June 29, 2014 you could hang over the layout from a rope like on those spy films regards, Sam. Link to post Share on other sites More sharing options...
Ron Heggs Posted June 29, 2014 Author Share Posted June 29, 2014 All the ceiling panel support structure is in place, and the first three panels fixed. Tomorrow, will relocate the lighting below the new ceiling, and continue fixing ceiling panels .... then it's back to modelling, before tackling the remaining 26m2 of the railway room 1 Link to post Share on other sites More sharing options...

Ron Heggs Posted July 1, 2014 Author Share Posted July 1, 2014 How many cans were used on this test? OzzyO. Edit, just seen post No 2215. Hi, Ozzy No cans were subjected to damage - these are reserved for bridges, etc. The suspension points were 6mm screw eyes with plastic plugs into concrete block ceiling, then using 1mm dia wire as the suspension dropper fixed to a test load of 200mm x 200mm x 200mm concrete block - no problems The suspension points support 21mm x 45mm timber runners at 750mm centres in their length, with timbers at 650mm centres - the plastic ceiling panels are 375mm x 2600mm x 8mm hollow rib (Grosfillex) - compared to the test load the suspensions are hardly carrying any load. Better to over engineer this structure as sits over the whole layout Cheers Ron 1 Link to post Share on other sites More sharing options...

Pete Hi, Pete At this stage not proposing DCC or computer The point motors will be Seep, and operated via CDUs and with diode matrix route setting - the CDUs have already been built with expansion capability if needed. The diode matrix for route control has also already been designed, and all the components are in my stock box awaiting time to build the circuit boards, and the display control panel Will post drawings and diagrams nearer the build time Cheers Ron Link to post Share on other sites More sharing options...
BR(W) Posted July 1, 2014 Share Posted July 1, 2014 I, for one, am surprised that you haven't constructed your secondary ceiling in the form of gothic fan vaulting - made out of styrene, naturally, and persuasively reminiscent of the cloisters at Gloucester cathedral. And all built within forty-eight hours, of course! Cheers, BR(W). 2 Link to post Share on other sites More sharing options...

Wouldn't want to take anything away from the layout Think the ceiling height above the train shed would be a problem at only 400mm - couldn't quite execute the vaulting in that space Cheers Ron Link to post Share on other sites More sharing options...

Ron Heggs Posted July 4, 2014 Author Share Posted July 4, 2014 The first section of suspended ceiling has been completed. The relocated lighting below a white ceiling, and which is also now 475mm lower gives much better illumination over the layout - almost like a sunny day in Manchester No pictures as the layout is still covered by plastic sheeting Now it's back to modelling for a week, then the remaining area will be tackled 3 Link to post Share on other sites More sharing options...
Ron Heggs Posted July 8, 2014 Author Share Posted July 8, 2014 Back on the viaducts. The upper track side walls are being completed First the south side wall between the CLC Deansgate bridge and the Cornbrook Viaduct bridge #1 - Looking towards the Cornbrook Viaduct bridge Looking towards the CLC Deansgate bridge - Plastic sheeting still in place beyond the bridge and across to the train shed Wall capping to be added ... then the north side wall between the CLC Deansgate bridge and the GN junction - CLC Deansgate bridge on the left GN junction on the right Buttresses, brickwork and wall cappings to be added The north side of this viaduct will need to be completed before tackling the GN junction viaduct because of the acute angle of the two viaducts at the junction little room will be left to gain suitable modelling access The supports for the viaduct track bed are displaced from the viaduct arch buttresses due to the position of the turnout motors on the trackwork above, but this isn't visually important as the viaduct arches were closed off by timber and glazing frontages 11 Link to post Share on other sites More sharing options...
