Bristol Barrow Road - Roundhouse Roof Trusses

The roundhouse kit of parts provided by York Modelmaking contained 13 roof trusses that were cut from 2mm mdf, but having made the decision to replace the two main girders with metal versions I decided to go the whole hog and replace the roof girders. Now I know some will think this to be foolish but I have concluded that the mdf versions are not robust enough to facilitate removal of sections of the roof for display purposes.   the mdf version of girders and trusses   This decision has no

Bristol Barrow Road - Turntable Pit for 60ft Cowans Sheldon turntable

I have been at Railex all weekend helping to operate our S4 group layout Brinkley. One of the highlights of my weekend was collecting the Turntable Pit for the 60ft Cowens Sheldon turntable used in the roundhouse.   Thanks are due to Morgan Gilbert for all his hard work with the design and the CAD modelling and to Phil Hutfield for producing the turntable pit on a CNC machine out of an acrylic polymer - [brand with-held].   I have attached some photgraphs which show the pit in position. Of n

Bristol Barrow Road - Pete Harvey PHDesign Buffers

Before I show the PHD buffers here are a couple of photos of the nearly finished set of buffers in position at the end of the head shunt.       Two sets of buffer stops on Barrow Road are very similar to the design catered for by Pete Harvey's etch, which consists of a set of suitably shaped brass plates and rail jigs. The following series of photos give an idea of the build sequence.               Two pads of double sided pcb have been added to the beam in order to

Bristol Barrow Road - Hitting the Buffers - Part 2

Having formed and soldered up the two main support structures     the main beam was formed from two pieces of rail each 30mm long. There is a narrow gap between the two rails so I used a short length of 0.2mm nickel silver strip as a temporary spacer during soldering. I also used two additional pieces to join the rails together.   I have since modified this by using a couple of pieces of thin double sided pcb to make the beam insulated from the trackwork - [ Mark, I have taken note of you

Bristol Barrow Road - Hitting the Buffers

I have done some research on the type of buffer stops used on the shed and have identified three different types in five positions:-   The first type is found on the headshunt alongside the coaling tower and has been difficult to identify as photos of this area have usually have a 16 ton mineral wagon blocking the view. I have managed to find a couple of useful shots one of which is courtesy of Patrick O'Brien on his flickr site:- http://www.flickr.co...157625157165429 The buffer stop is to

Bristol Barrow Road - The Four Sidings

I have now finished laying the four sidings which are alongside the roundhouse and workshop, the track over the pits laid using Exactoscale M1 chairs. I have extended the track on the engine release road - in one of the photos there is a section of this track with one length of rail positioned using pins - but this is as far as I can go with this track at the moment as the templot drawing needs adjustment to the south exit trackwork. All the new unstained trackwork is still in need of the additi

Bristol Barrow Road - The engine sidings

More progress on the trackwork this time on the engine sidings alongside the roundhouse. In addition to the two main lines there are five other lines which cross the board joint at the throat of the sidings. Track fixing across this joint, as all board joints, is by positioning ply sleepers adjacent too, and across the joint and inserting 12BA brass bolts into pre-drilled holes in the ply sleepers. I usually do this on two or more sleepers either side of the joint.   One length of rail - 120f

Bristol Barrow Road - Trackwork Update

Most of the trackwork in and around the coaling and ash plants is now ready for attaching the droppers, however my next task will be to complete the approach and four sidings, with their pits, alongside the roundhouse and workshop. I'm very pleased with the progress over the past few weeks as I have got into the swing of producing lengths of track using timbertracks sleepers as exactoscale chairs. Of course the track assembly jig I borrowed from my friend Graham has helped enormously.

Bristol Barrow Road - an interlude

On friday my former LMS crab returned from the Severnside Works paintshop for a test run up the main line. Formerly 2798 it has re-emerged as BR 42763. Here are some before and after photos.         The Hawksworth coach is a modified Hornby with drop in P4 wheelsets and has been weathered for it's owner, Morgan, by Gerry Beale.   Another visitor was a Gresley RB dia 167 in BR rebuilt form which Morgan has started to build for the Bradford train.         And finally a shot o

Bristol Barrow Road - Point Motor mounting

Having decided to use the new Cobalt digital point motors with the Brian Morgan TOUs I thought a few photos would be in order to explain how I have decided to fix them to the underside of the baseboards.   The Cobalt motors are attached using M3 screws fixed into M3 Rivet Nuts, positioned in the baseboards using the rivetting tool shown in the photos. The position of the 4 holes is marked using a home made jig, whilst the hole for each TOU has been cut out using the Bosch multitool.

Bristol Barrow Road - Wagon hoist Pit and more trackwork

Having promised some photos of recent work on the layout I managed to find time today to take a few. Time had come to cut a suitable hole in the baseboard to fit a removable pit to accommodate the wagon hoist apparatus for the 150ton Coaling Plant, so out came the drawings and after taking the appropriate measurements I marked out the outline shape and literally took the plunge using my Bosch multi-tool - what a useful piece of kit.   I then made up a removable pit which is bolted to the under

Bristol Barrow Road - Back on Track 2

Following RMweb taking it's unscheduled Christmas break I realise I have not posted anything for a while. Further progress has been made on the main line with both centre boards now having the C&L flexitrack replaced by ply and rivet track. Limited modelling time over the Christmas festivities has seen all 4 lengths fixed and fully chaired with the ply sleepers stained with Coldron dye. All the main line track is now in position ready for the droppers to be attached.   Here are a few photo

Bristol Barrow Road - Back on Track

It has been a while since I updated my blog so I thought it was time to let you know what progress has been made.   I have finally completed the first batch of 15 turnouts and one double slip. These are all now fitted with Brian Morgan TOU's and are ready to be installed on the layout. I have also finished the task of making a further 8 and a double slip for our Scalefour Society area group layout Brinkley [ attending Railex next year ].   Whilst at the Manchester Show in October I decided t

Bristol Barrow Road - Brian Morgan TOUs for pointwork

As mentioned in previous posts I have decided to use the Brian Morgan turnout operating units for all the pointwork on Barrow Road. Brian has produced some superb etches for B & C switches in P4 which can be obtained from the Scalefour Stores. His main interest is the GWR and whilst the original units were designed specifically for Great Western loose heeled switches he has also produced the other version for non GW railway turnouts.   The TOU etches, one for the standard B, C switch, th

Bristol Barrow Road - Shed STOP sign

This morning I decided to have a short interlude from trackwork and completed work on the shed entrance STOP sign produced for me by Chris of York Modelmaking. After spraying it yesterday with Halfords red primer and finishing with Humbrol 5070 acrylic red I spent around half an hour carefully removing the paint form the raised lettering and lines before fixing it to the front wall of the roundhouse. A rather pleasing result.

Bristol Barrow Road - Trackwork Update

After what seems ages I have now completed the first 18 sets of pointwork for the layout. By completed I mean all trackwork shown in the attached photos are now fitted with Bill Bedford slide chairs, Palatine models electrical droppers, are electrically bonded in the appropriate places and have been fully fitted with cosmetic [ around the track rivets] and functional chairs.....what a job!   The next task is to fit Brian Morgan turnout operating units..................these will be the subject

Bristol Barrow Road

It's been a while since I posted anything about Barrow Road what with holidays and sorting out the garage not to mention helping my son move to London for a new job.   Yesterday evening I hosted an evening for several members of this illustrious community who wanted to see what progress had been made since their previous trip.   What progress? - well not a great deal on the layout although I am making some, if slow, progress with the trackwork. Last night Morgan brought the 8F, now 48079,

Bristol Barrow Road - Back on track 2

More progress this week with the completion of 6 turnouts - droppers; TOU base plate and all the cosmetic chairs in position - what a job Yesterday I stained the sleepers using Colron Wood Dye - Jacobean Dark Oak with pleasing results. I have now started on the three way turnout leading to the shed sidings......... still not half way there yet   Anyway here are a few photos taken before the stain was added.     C8 crossover on the main line with the north exit leading to a double slip

Bristol Barrow Road - Back on track

It's been a while since my last post but I haven't been wasting time. I purchased three magnificent scratchbuilt P4 locos after meeting Graham Warburton at the Taunton members day; a Patriot, 8F and Crab, all of which were in LMS livery. After much heart searching I made the decision to remove this livery and have them repainted and renumbered in BR livery to suit my 1950/60s modelling period. With the help of my friend Morgan all three had their paint stripped and removed and the 8F and Crab a

Bristol Barrow Road - Roundhouse Roof Girders - another rivetting day

I've had a few days off from Barrow Road at Railex with my other layout Sheep Pasture, a Cromford & High Peak subject.   Sheep Pasture at Railex   [ See Kempenfelt photos of layout dated 2nd June - please ignore his earlier post ]     I'm now back on the job finishing the girders, both long and short, by forming all 1400 rivets in the overlays for the top and bottom of the girders.   Here are some photos taken today during completion of all the girders - trial assembly revealed the

Bristol Barrow Road - Roundhouse Roof Girders - Update 3

Having measured the remaining stock of 5mm x 3mm slotted 'T' section I was pleased to find my calculation for the original order was just enough for the 8 pieces required for the top and bottom parts of the short 19ft girders. It did mean that 3 pieces would formed from off cuts - two per girder which is better than purchasing more .   The wall end of each of the four 19ft girders will have downward extensions to form the wall fixings. During fabrication I soldered a 2mm x 0.5mm piece into a c

Bristol Barrow Road - Roundhouse Roof Girders - Update 2

Well it's been a while since I posted anything on the progress of Barrow Road. After an enjoyable day out at the members day at Taunton I returned to domestic duties and have finally managed to decorate two rooms in the house which included replacing the flooring.   I have now returned to more interesting tasks and have made some progress on the girders for the roundhouse roof. I have nearly completed the six 46ft long girders but have run out of 2mm and 2.5mm 'T' section brass so further wor

Bristol Barrow Road - Proxxon Cut Off Saw - Photo request

In response to a request from Tim here are a few photos of the saw. I have just used it to cut the other 5 pairs of 'T' section for the top and bottom of the 46' girders hence the brass 'dust'.   There is a yellow safety cover for use during cutting - photo 2 - but it is removed in photo 1 to facilitate accurate lining up for the saw cut - once lined up the cover is put back in place for the cutting operation. As these 'T' sections are 179mm I was not able to use the stop fence - see photo 3

Bristol Barrow Road - Roundhouse Roof Girders - Update

I purchased a Proxxon Cut off saw a few weeks ago to enable accurate cutting of the brass and nickel silver sections required for the roof girders and eventually the roof trusses [ the likely follow on project after the girders ].   I did send the first one back after discovering a problem with the on/off switch - it tripped the RCD each time I switched it off! The replacement appears to be alright and I have used it to produce all the diagonals for the lattice girder with pleasing results.
