Ron Heggs Posted January 6, 2015 Author Share Posted January 6, 2015 To fix the third cladding strip to the train shed roof, sixteen clamps will be needed for each longitudinal edge (one for each span beam fixing point). Therein lies the problem - with only a 25mm x 20mm x 15mm triangular space to get a clamp in, and with a clamping height (open jaw height) of 24mm, it appears that such a clamp is not available, and I will have to produce a suitable clamp. The clamping pressure required is fairly low Have drawn a possible solution based on 60thou styrene sheet - Assembled view Exploded view Jaw depth - 15mm Jaw Opening Max - 40mm Post/Handle - 75mm x 10mm Jaw locking by tapered peg It is possible to lower the Top Jaw with the Post/Handle down through the triangular opening from above, thread the lower jaw from below, and tighten the clamp using the tapered peg .... off to do some styrene cutting, assembly and testing 2 Link to post Share on other sites More sharing options...

Or just face the clamp faces with a bit of tin foil. OzzyO. Link to post Share on other sites More sharing options...

hayfield Posted January 6, 2015 Share Posted January 6, 2015 Ron I have a couple of plastic clamps much the same but a little larger which came from model aircraft store Link to post Share on other sites More sharing options...
artizen Posted January 6, 2015 Share Posted January 6, 2015 Can you not use sticky tape? Add the cladding strip and hold in position with blue tack or weights etc and then feed tape up and over the strip and pull down to pin into position? Might not be possible given the dimensions you have posted. Link to post Share on other sites More sharing options...
LongRail Posted January 7, 2015 Share Posted January 7, 2015 Ron I have some clamps which would fit the bill and which were brought quite cheaply form local diy store and cheap shops depends if they are available in Spain will post a photo later. I use them for all sorts of purposes and at them moment mainly to hold components during spraying Link to post Share on other sites More sharing options...
runs as required Posted January 7, 2015 Share Posted January 7, 2015 Los mejores deseos para 2015 Ron. It is my first visit to the project this year and it really is uncanny to see the lighting and interior atmosphere of that great space re-appearing. I have a question for you. As a frequent user of the old Central station I was forever disappointed with the improvised timber weatherboarded main elevation facing across to the Midland Hotel. I'd like to ask whether you have ever considered conceiving and modelling an alternative "what ought to have been" facade? It could be interchangable to the actual elevation that Cheshire Lines promised would be 'temporary' but which turned out to be permanent. In my mind as I approached, I always pictured something like the gothic arcades to Tiviot Dale with fenestration to offices above in brick and stone, with the great arch of the train shed and its clock oversailing everything behind. dh Link to post Share on other sites More sharing options...

Thanks for your suggestion, Ian The 'strip' is 129mm wide with black card upper surface, needs to be clamped to the curved span beams along the length of both edges. Couldn't easily achieve that with tape, but possible with lengths of string 1 Link to post Share on other sites More sharing options...

LongRail Posted January 8, 2015 Share Posted January 8, 2015 Ron, This is the clamp I was referring to the top can be removed and replaced which would help it fit through a small gap. They are very useful little items and find all sorts of uses. Link to post Share on other sites More sharing options...
LongRail Posted January 8, 2015 Share Posted January 8, 2015 Ron, A quick search of ebay £3.21 a pair plus postage you would get a combined rate for 8 pairs http://www.ebay.co.uk/itm/6-150MM-QUICK-RAPID-Light-Weight-RATCHETING-BAR-CLAMPS-x-2-/290778793750?pt=UK_Hand_Tools_Equipment&hash=item43b3c44716 Link to post Share on other sites More sharing options...

Ron Heggs Posted January 14, 2015 Author Share Posted January 14, 2015 Simple ideas are usually the best - have discarded the small clamp idea (to save time & material), and gone for a simple long clamp made from two pieces of wood strip and two machine screws and nuts Working out just fine. Two more bays to go, then it's the apex vent to build 16 Link to post Share on other sites More sharing options...

Ron Heggs Posted January 22, 2015 Author Share Posted January 22, 2015 (edited) The Correos delivered a couple of packages this afternoon - expected a couple of weeks ago, but the poor weather conditions in the UK recently must have had an effect on postal deliveries just after Xmas Package 1 - The missing two etches for the Castlefield Viaduct Overhead Span Beams Package 2 - Styrene and glazing sheets for the Train Shed May be able to make some progress now - If I can find the time from painting the villa and redecorating one of the bedrooms Edited January 22, 2015 by Ron Heggs 1 Link to post Share on other sites More sharing options...
Horsetan Posted January 22, 2015 Share Posted January 22, 2015 Happy New Year to All Just managed to fix the first seven spandrels in place, after a long day in the garden clearing leaves, weeds, pruning last year's growth and picking a few oranges. Now posting the pictures with the sun just setting behind the mountains at the west end of the valley - ... and it's only the first day of the New Year In the railway room all is quiet and the only light is from the overhead fluorescent fittings - with chocolates in one hand and a beer in the other, now is the time to press the shutter ... and that's the last of the poetic ramblings, on with the modelling IMG_1961.JPG View from platform level IMG_1962.JPG View from eaves level IMG_1963.JPG The gable transom comprises two span beams, and therefore has two spandrels, just about visible The walls definitely need more detailing before being fixed, and the eaves glazing constructed Phwoarrrrrr!
