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

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 View from platform level View from eaves level 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

Have fixed the three lengths of cladding to the roof structure, ensuring the appropriate locations using temporary card spacers. This also helps in maintaining the correct dimensions for the glazing Have to now order the clear plastic sheets (the sheets in my stock are too thin for canopy and roof glazing, but ok for windows, etc.) and of course more styrene, as none of this is available in Spain. In the meantime whilst awaiting delivery, will sort out the spandrel fixings, eaves glazing bars and apex vent, then it will be back to the trackwork

The last of the Xmas Concerts and Carols in the Local Church have been done, and the Xmas Presents to the local charities distributed - ... and inbetween times the second cladding strip has been completed, and placed temporarily on the train shed roof. The first cladding strip is 38mm wide by 2045mm long, and the second strip is 56mm wide by 2045mm long - The train is still on Platform 6 Closer view of the two claddings Closer ... and closer ... the third cladding strip is wider and stepped to provide greater glazing area over the concourse

Hi, Ozzy The Spandrels were etched back in September 2011, and have recently been painted ready for mounting The spandrels are shown in the bottom right corner Drawing of a typical Spandrel Edit: Just remembered my post http://www.rmweb.co.uk/community/index.php?/topic/28293-manchester-central-clc-gn-warehouses-castlefield-viaducts/page-39&do=findComment&comment=502778 , and following relevant posts, with some pictures of the etches

David, here is a quick picture of six Mk1 carriages (in no particular order) and a Britannia loco - the external canopied platform extension would allow at least another five carriages The rolling stock is placed on the platform, as not enough straight track is available yet, and the platform hoist is not in place Ron

The roof has been 'blown' with vintage 2012 spray paint, and the first of the cladding placed in its location at the roof eaves. Will fix when all the cladding for one side of the roof is complete Looking South along East Wall Closer view Closer still Looking North along East Wall Closer view External view over cladding

Plasticweld is DichloroMethane is OK for Styrene, but not ABS. MEK can be used for both by capillary action. There are definitely variations in styrene extrusions, strips and sheet Can now only obtain MEK in Spain. It's used to clean the joints of uPVC pipe and fittings before using jointing cement Have finished the new tie beams, and they are all fixed in position with no problems Ron

Using black card for the outer cladding, and white card printed with timber planking on the inside, both fixed to a 40 thou plasticard core. This is then edged with 2mm RSJ styrene extrusion to enable the whole to be fixed to the roof structure. Additional styrene extrusions are used to carry the glazing strips From experience the styrene strip only shatters when using MEK, but only infrequently. Have found no common cause The shattered beams have been dumped along with other household waste in the local disposal skip. If it happens again will post pictures of the damage Ron
