Torr Giffard LSWR 1951-71 Posted February 27, 2012 Author Share Posted February 27, 2012 Sage advice received from the manufacturers of the Green-lee slugbuster cutter used to create the 1 inch holes in the aluminium end plates to house the em gauge society locating dowels. Apparently, they are not designed to cut through 7mm of aluminium in one go and this is the reason for the failure of the main bolt in mine. I now need to come up with an accurate method of cutting the holes one at a time. This will probably involve centre drilling them as a pair, separating them at that point and slug busting them individually. 2 replacement bolts ordered (1 spare) at £9 a go. Time to experiment! Whilst waiting for the postman to deliver the new bolts progress can be made on designing the adjustable feet on the 3 supports per baseframe. Given the overall length of 58 feet for the layout considerable adjustment needs to be available within the supports to compensate for uneven floor surfaces at the planned exhibition venues. The current minimum adjustment value that I'm working with is 6 inches, achievable with the use of threaded bar and locknuts for adjustment as the layout is being erected. Tracked baseframes will be equipped with permanent spirit levels as required to ensure that they are absolutely level prior to the scenery baseframes being added.

Torr Giffard LSWR 1951-71 Posted March 1, 2012 Author Share Posted March 1, 2012 Evenin' all, Here is the latest progress video showing the prototype baseframe support of which each frame will have 3. Each 2ft support will have 6 inches of vertical adjustment to compensate for uneven exhibition venue floors, uses T section aluminium for strength, the long hexagonal nuts through which the M10 height adjusting thread passes are studding connectors with the lower one loctited to the thread for spanner adjustment, M10 nylon threaded bar is on order to screw into the lower half of each of these so that each support has nylon in contact with the floor and won't mark or damage it. The L brackets holding the adjustment mechanism in place are simple corner braces secured with M4 countersunk machine screws and Nylok nuts. The top of the support uses similar techniques with the corner braces but the male half of an EM gauge society dowel is mounted on top and locates in the base of the aluminium angle of the baseframe. The male stud had a flat filed onto its side so that I could drill a 2mm hole through it and secure the support to the baseframe with a simple wire nail, reducing set up and dismantling times. A baseframe table will be an important part of the kit, just high enough to allow each frame to have its 3 supports fitted and secured or else removed at packing up time. The weight of the baseframe will be equally divided between 3 supports with the dowel acting as the contact point between the two http://www.youtube.com/watch?v=CTR78Db_rsM&feature=youtu.be The replacement bolts for the slugbuster also arrived this morning so more progress with the baseframes should follow.

andyrush Posted March 1, 2012 Share Posted March 1, 2012 Hello Dave My main modelling interest is supposed to be BR (ER) 1956 - there is a somewhat defunct thread entitled 'Twenty Feet River' about it, but the last 18 months or so have been largely devoted to helping to produce the Great Eastern Railway Society Journal and playing with big trains in the garden during the summer. Oh, and operating other peoples train sets at exhibitions. Meanwhile, I follow about half a dozen interesting threads on here which will hopefully inspire me to carry on with my own project. Keep up the good work. Andy Link to post Share on other sites More sharing options...
Torr Giffard LSWR 1951-71 Posted March 19, 2012 Author Share Posted March 19, 2012 Aft'noon all, Normal service resumes after a couple of weeks off the south west coast of Florida.....brrrrr, its a bit nippy back here! The M10 nylon studding lengths arrived from ANIXTER of Wimbourne and the first section has been loctited into the base of the prototype support. The principle of this type of support appears sound and it has easy (spanner) adjustment through 6 inches. The other 2 for the first baseframe are now underway. The website below has had a good number of useful and relevant (for any North Devon modellers) images added recently http://www.cyber-her...2028.11.86.html Cheers Dave Link to post Share on other sites More sharing options...
Torr Giffard LSWR 1951-71 Posted March 23, 2012 Author Share Posted March 23, 2012 Aft'noon' all, The rolling stock for TG is being added to on a regular basis with a Beattie well tank by Dapol being ordered from Kernow this morning. Nick Allsop (one of our group of 3 for this project) has promised a Hornby 'West Country' from his collection too, these accompany the Hornby T9. Where possible these will be re-wheeled with Ultrascale wheelsets. The diesel fleet is being steadily added to as well with 2 Bachmann Warships and a Heljan Hymek standing alongside the 2 Dapol class 22s. The forthcoming reprint of 'The North Cornwall Railway' by the Irwell Press will also be an automatic purchase. Cheers Dave Link to post Share on other sites More sharing options...

RMweb Gold Oldddudders Posted March 23, 2012 RMweb Gold Share Posted March 23, 2012 Hi Ian, Thanks for the gen. I have a copy of the original version and that it is proving invaluable so the 2nd reprint should be something special. Are you modelling at the mo? I should be, but ain't. Getting ready for major works within the house which start in earnest on Monday and go on for a couple of weeks at least. We may have to move out for part of that time, as the kitchen will be destroyed (partition walls down, new floor etc) and even getting to the loo will be a challenge!

Torr Giffard LSWR 1951-71 Posted March 24, 2012 Author Share Posted March 24, 2012 Ian, Hope that they go well and that all is completed to your spec asap. Sorry to read of your wife's accident. The Beattie arrived today and is exquisite, the P4 conversion may be a challenge but I can't be the only one contemplating it. Regards Dave Link to post Share on other sites More sharing options...
Torr Giffard LSWR 1951-71 Posted April 3, 2012 Author Share Posted April 3, 2012 Evenin' all, Another solid day put in on aluminium work by Colin and myself. We now have 3 complete adjustable supports and 2 pairs of end plates. The slugbuster is working well with its replacement bolt providing that single aluminium end plates are 'punched' rather than pairs and the thread is lubricated e.g with coppercrest grease. Pairs of end plates are aligned on the plate glass surface, carefully G clamped then centre drilled at each end to allow M4 machine screws and nuts to clamp the pairs together for accurate drilling ready for the slugbuster bolt to pass through. Once the finishing touches are applied to the 2nd pair of end plates then work will begin on the T section logitudinals which will connect them. The first baseframe tackled is likely to be one of the 6 x 2 feet fiddle yards, each of which will be equipped with a turntable capable of turning a West Country pacific and an end traverser to 'release' locos arriving on inbound trains. Current space saving thinking is that the turntable can be mounted within the traverser on each board. One of the 3 adjustable supports per baseframe is likely to be located amidships to counter the unlikely issue of sag or deflection esp. on the 6ft fiddle yard boards.

Torr Giffard LSWR 1951-71 Posted April 4, 2012 Author Share Posted April 4, 2012 Evenin' all, Whilst the construction of TG progresses consideration is also being given to the storage of its various components. The layout will need to be stored on a form of shelving/racking along each side of the workroom in which it is being created. A layout of this size is going to need a well organised storage system in order for construction work to continue alongside partially complete and completed frames. The most efficient use of space possible may be able to allow for pairs of train running baseframes to be stored in an operable state so that testing etc can be done on a routine basis in situ, the purely scenic frames will then occupy the other available spaces around them. A further consideration is that adopting largely 6 feet x 2 feet baseframes will reduce the number of baseframes/end plates/supports etc needed whilst speeding up the project and making the completed layout even lighter and less bulky to transport. Also, it may be possible to design adjacent frames to overlap their neighbour and thus allow locating dowels to be used longitudinally as well as laterally, resulting in a pattern of interlocking frames holding each other securely together in exhibition mode. Additionally,it is important to look at where the pointwork falls relative to baseframe joints on the Templot trackplan so that baseframe lengths can be adjusted if necessary to ensure that joints occur beneath plain track.

Torr Giffard LSWR 1951-71 Posted April 13, 2012 Author Share Posted April 13, 2012 Evenin all, Current progress is dominated by the design and construction of the racking and storage system for TG which will enable the baseframes to be given a home as they are produced. The same 'T' and 'L' aluminium sections are being used as for the baseframes themselves. All parts of the layout will need to be housed within the same 17 feet by 8 feet by 7 and a half feet room. I'll do some camcorder footage of progress thus far. Dave Link to post Share on other sites More sharing options...
Torr Giffard LSWR 1951-71 Posted April 24, 2012 Author Share Posted April 24, 2012 Mornin' all, Work continues on housing the layout and constructing the first pair of baseframes see video The plate glass reference surface and careful construction techniques are paying off with the baseframe sections aligning perfectly first time.

Torr Giffard LSWR 1951-71 Posted April 29, 2012 Author Share Posted April 29, 2012 Aft'noon all, The final version of the Plymouth/Barnstaple end fiddle yards is still being considered, one possibility is this linked version which will prevent the china clay opens appearing sheeted or empty in both directions. A design for the traverser has been drawn up and will allow for the 2 x 2ft turntables to be wound along the 6ft x 2ft baseframe (which will be mounted at right angles to the other frames) to meet amidships and facilitate stock transfer as well as the usual reversing of locos and shunt release. The moving parts of the traverser will use T section aluminium sliding within 2 L sections and the turntables will use a further 2 centrepinned L sections arranged to form a cradle again to protect stock. Full length studding sections locating into studding connector nuts and operated with handwheels will provide for accurate sliding of the traversers. Precision positioning of the turntables wil be achieved using sprung centering bolts. The fiddle yard roads are at 50mm centres and will provide ample storage for many years of stock building. Considerations for the length and speed capability of the faster fiddle yard roads include receiving and holding 9 coach formations at a scale 40 mph. The 4 faster/longer routes are likely to be central on each frame whilst the shorter and slower roads will have fanned out to the sides. Electrical considerations are foremost with this design with isolated sections adjacent to the traversers to prevent stock damage due to loss of concentration. Push and hold power supplies will then ensure concentration on the final approach. The next section inboard on each road is likely to have continuous low voltage to reduce the speed of any move approaching the dead section and provide a mandatory speed limit in risk areas. Current challenges include balancing the creation of frames with that of suitable storage locations whilst maintaining the necessary workspaces.....oh, and fitting in a full time job as well.

Torr Giffard LSWR 1951-71 Posted April 30, 2012 Author Share Posted April 30, 2012 Evenin' all, Another days work on TG see http://www.youtube.com/watch?v=whvWLSKFlfA&feature=youtu.be the 2mm aluminium sheet even when slitted at 2ft width proved more robust than necessary and added considerable extra weight to the 1st fiddle yard frame (an opinion revised once the 1mm sheet started to deflect under load) so 1mm sheet has now been ordered instead and the 2mm will be used in pieces between various frames as work progresses. T section stretchers at 1 ft intervals will support the sheet deck of the frame. Narrow tabs will be slitted in the sheet and folded down for securing to the stretchers, this should prevent distortion of the flat sheet surface on which the cork sheet then track will be laid. Sufficient support frames are now in place for the 2 Plymouth end fiddle yard frames to be erected together or else the linking traverser frame and adjacent Plymouth end frame. The fiddle yard frames will be the heaviest due to the full width of track (11 roads) needing wide stretchers and full width sheet, the narrower track bed of the other frames will allow the T section longitudinals to be closer together with scenic polystyrene filling good percentages of each frame.

Torr Giffard LSWR 1951-71 Posted May 4, 2012 Author Share Posted May 4, 2012 Evenin all, The P4 wheelset conversions for the 2 Dapol class 22s arrived back from Ultrascale today and at first glance they have done a superb job of turning the original aluminium wheels and fitting steel tyres. Next in line with them is an order for wheelsets for the T9 and its 2 coach Maunsell rake. A full day on TG today with Colin saw the stretchers for the first fiddle yard frame produced and fitted whilst a sizeable aluminium delivery mid day allowed the slitting of the first 1mm aluminium frame deck see http://www.youtube.com/watch?v=53TxToL41Ps&feature=youtu.be . This still requires some fettling and for the tabs to be cut and located onto the stretchers. Once the sheet is secured absolutely flatly across the frame and stretchers then the end fences will be added to protect the stock. The sheet finishes just short of the frame edge to provide space for the end fences to be bolted to the frame. Current considerations include which style of station buildings to adopt: a broadly similar Crediton style approach with corrugated goods shed or else given the rocky and wooded river valley setting of TG adopt a local stone approach similar to Torrington. Any thoughts anyone? Cheers Dave Link to post Share on other sites More sharing options...
Torr Giffard LSWR 1951-71 Posted May 5, 2012 Author Share Posted May 5, 2012 Aft'noon all, Further Templot work on the linked west end fiddle yard of TG has resulted in this interim stage the adjacent Barnstaple end yard will be similar. The length of the proposed Plymouth end yard is around 19ft which adds to 19ft of scenic section and a further potential 19ft at the Exeter end for the fiddle yard.....the potential max dimensions of TG are currently 57ft x 10ft.

Any thoughts anyone? I think the stone makes the railway seem more permanent, as your chosen location of a key junction would still be, actually. Stone isn't the easiest finish to get "right" but there are several exponents on RMweb who have shown how to succeed. 2ManySpams has done excellent - but different - stone on Treneglos and DITD, for example.

Torr Giffard LSWR 1951-71 Posted May 5, 2012 Author Share Posted May 5, 2012 Hi Ian, The oft heard logic of using what is to hand would also support the stone approach. I've seen some of the lovely weathering and realistic representations of natural materials on others sites and readily agree that it'll take some serious concentration to be comparable.

RMweb Gold Oldddudders Posted May 5, 2012 RMweb Gold Share Posted May 5, 2012 How is Halwill progressing? Well, the builders left yesterday, our mate will be back from honeymoon on Weds, to tidy up a few more bits and pieces, so all is set for life to be a bit more relaxed. I hope to get serious on Halwill in the next few days. I haven't been entirely idle, with some detailing work on French railcars for another project, but Halwill does deserve the effort. After all, the track is laid, the electrics are in place, I have a couple of really nice buildings plus some more ordinary ones - just need to get a**e in gear!

Torr Giffard LSWR 1951-71 Posted May 6, 2012 Author Share Posted May 6, 2012 By the way Ian...happy haircut :-) Kings Nympton station buildings are attractive, have plenty of character, are of stone and less frequently modelled. We have plans for 2 of the standard wooden SR signalboxes which tie in with this area too. When do we get to see some progress pics of Halwill...or have I missed where they already are?
