Mayner Posted August 7, 2019 Posted August 7, 2019 One of the challenges in designing kits/models of the smaller long lived GSR/CIE locomotives is capturing the many variations between individual members of a class that arose following the Amalgamation. My kit of the GSR/CIE 650 class covered 5 different variations of the class but excluded the locos in their original and superheated state with Attock-flyaway cab and the Y Boiler version with Belpair firebox. I am building a Y boilered version of the class as a commission & it was simpler to produce a new version of the kit than scratchbuild a new boiler firebox and smokebox and new spectacle plate. I expect the Y Boilered version of the loco to be available to order from September 2019 for $250 NZ + $20 shipping please P.M. if interested The Belpair boiler and heavily riveted smokebox of the Y boilered version gives the loco a more massive appearance compared to the locos with round topped fireboxes although boiler diameter and overall length of boiler,firebox and smokebox are the same for the two varieties. 6 Quote

Mayner Posted September 22, 2019 Author Posted September 22, 2019 A bit more progress with the Y Boiler 650 Class following an amendment to the design of the smokebox-wrapper. Unfortunately the engravers managed to add an error or two to my own in updating the photo tool delaying release of this particular variation of the class. The dome and chimney were just plonked on the loco and require further fettling and adjustment before final fixing in position, some tweeking is required to the handrail at the firebox end. MGWR 1918-1934 superheated version for comparison. The GSR & CIE maintained both the Belpaire and Round topped 650 Class boilers in a common pool, with a number of spare boilers available to speed up the repair and overhaul process. GSR developed its own utilitarian style of loco detailing during the 1930s, quite distinct from the styling of the 1920s. 5 2 Quote

Mayner Posted October 12, 2019 Author Posted October 12, 2019 A bit more progress with the Y Boiler 650 Class. The chimney appears to be high despite having reduced it in height. The modified chimney will be used as a master for a cast brass chimney, I also need to produce a master for the valve that sits at the back of the smokebox behind the chimney. The loco and tender is on chassis borrowed from the test build for the original kits. I suppose if there is sufficient interest the next step is to design a fly away cab as an 'add on" for the original kit for those that want to build the loco in its original condition, resulting in a potential 7 different variations of a class of 19 locos in GSR days. 5 3 Quote
jhb171achill Posted October 12, 2019 Posted October 12, 2019 Looking good - can't wait for mine! Great to see so many variations possible. Maybe a D16 "Achill Bogie" or a GSWR D14 or D17 next! 2 Quote

Maybe a D16 "Achill Bogie" or a GSWR D14 or D17 next! Careful what you wish for JHB! A Midland Standard goods is next on the list ( I need 2-3) once I have completed the 52 Class, possibly followed by a Cattle Engine and a Connemera Class 4-4-0 to round out the fleet for a Mayo/Sligo line layout. An Achill Bogie or D14 are not currently on the list, though the Bogie shares a lot of common parts with the Standard Goods & 650 Class JMD GSWR 52 Class loco designed to run with SSM GSWR tender & detail castings. Loco is modeled with raised round topped firebox and cab can be assembled in its original stylish GSWR format or extended CIE form. Recently arrived test etches for 52 Class. Next step test assembly (once I have completed the 10 locos currently on my workbench) check if everything fits together and make any necessary corrections. Test etch is in nickle silver rather than brass, which has the advantage in terms of strength, ease of soldering and paint base, downside more difficult to curve without annealing. Chassis is designed for OO or 21mm gauge rigid or compensated with (non working) inside valve gear. Edited October 16, 2019 by Mayner 3 1 Quote
leslie10646 Posted October 16, 2019 Posted October 16, 2019 Careful what you wish for JHB! Ah, but be careful what you say, Mr Mayne! "I suppose if there is sufficient interest the next step is to design a fly away cab as an 'add on" for the original kit for those that want to build the loco in its original condition" Well, I'd prefer one, so there's ONE! As for a Class L 0-6-0, well ........ Probably not the best time to tell you that I've had to replace my 13 year old Smart Car (its DCC chip wasn't reliable any more) with a five year old one, so I'm impoverished! Keep up the good work, John! Quote
DiveController Posted October 17, 2019 Posted October 17, 2019 (edited) The class 52 has fairly long lives maybe not to the end of southern steam but certainly into the late 50s. Not sure if I missed the announcement but I'd take a Class 52 also. The L class had pleasing distinctive look with that flyaway cab. Edited October 17, 2019 by DiveController 1 Quote

Keep up the good work, John! I am sure we can sort out a K or Ks with a flyaway cab for you Leslie! Its more a question of whether there is sufficient demand to justify producing a set of etched parts rather that scratchbuilding a flyaway cab in connection with a one-off commission. I am planning to produce the 594 Class or J19 version of the "Standard Goods" in GSR/CIE condition with X superheated boiler rather than attempt to incorporate the three distinctive variations of L Class in the one kit. The Cattle Engines and rebuilt Celtic and Connemara Classes are a lot more straightforward than the re-built Attock engines. Rebuilt L Class 603 with GSR X Superheated Boiler and slotted valences. L Class 600 rebuilt by MGWR c-1913 with saturated Belpaire boiler conventional cab, sandbox splashers Stirling tender. L Class 67 Dublin original (pre-1903) condition Edited October 18, 2019 by Mayner 1 Quote
Mayner Posted October 28, 2019 Author Posted October 28, 2019 Completed the final patterns for the Y Boilered 650 Class today, short GSR "built up" chimney and turnings for vacuum relief valve and whistle, these will be used to prepare moulds for brass castings. The model is based on a loco running in the late 1930s which still retains the mountings for the original laminated springs on the leading axle. Rather than produce a complete new master for the chimney, I cheated by slicing the top off and existing chimney, reducing the height of the straight part, turning an insert to fit inside the chimney and re-joining with loctite Sliced and diced chimneys.
