Thread: Designing Model Boilers (Thermal Design) |
24/07/2018 17:37:02 |
HI Martin Thank you for posting this work. I build and run in the smaller gauges of 2 1/2" and 3 1/2" and am looking at way to improve the locos i run. I have been concentrating most of my efforts of late in to the exhaust set up, although i have been tinkering around the fire box end, with stainless arch and rosebud grate. Reagrds Will |
Thread: Austerity Locomotives |

Hi Jon Nick Feast in a member of the local club, and his fleet (he has 3 Q1's!) all run well. It is a good size, in that its not too heavy to lift into the car/work bench or track. I belive that he has updated the drawings to remove any errors. I am building one in 5" gauge (thats the link to it at Model pro boards) Its worth dropping Rob Spears a email a Bulleid builders group, there is a lot of information on them. The Myford should be fine for the 3 1/2" gauge loco. I remachined the wheels on my Drummond with no problems. Cylinder block could be machined between centres or on a Keats angle plate. Will |

Homebase of all places sell small braised link chain. I picked some up last year for my 2" Fowler. I think this is the chain: https://www.homebase.co.uk/brazed-oval-chain-chrome-plated-1-5-x-2000mm_p807579 Will Edited By william Powell on 20/03/2018 14:17:17 |

Just a reminder of the event, and a video of Canterbury Lamb running on the little down track on Easter Monday. |
Thread: 3 1/2" Gauge Discussion Group |

Neil has mention about the Bournemouth Rally on the 25th April. I started building (and still need to finish it!) a 5" gauge Dewinton. Its not a large loco but still a large lump, even for a young (just past 30) person. I picked up a part build slip eccentric Juliet (i have since sold her) finished her and run her for 2 years at the Littledown track and visting other clubs. She was simple but a fun engine to drive and taught me a lot. To take her place i upgraded to a Canterbury Lamb, i don't think she is even half the size of Juliet! I really enjoy driving her, she keeps me on toes when steaming around the Bournemouth track. Next in line on the work bench is a 2 1/2" gauge Ayesha, the loco that showed it was possible to pull a adult and help shape the future of ME clubs. I do enjoy driving the club Speedy when passenger hauling, but there is something about running a smaller loco even if it just you who is being pulled around. Also these day with the ever increasing costs of materials its value for money. Interestingly not a week goes by with out parts or a complete small loco is on ebay, there always seem to sell, are people finishing them? Will |

Thread: Titch or Juliet |
17/01/2014 14:41:10 |
Hi Bob I run both a 3.5 "Juliet and a 5" Speedy. Apart from charity and open days were Speedy is working hard pulling loads, i much prefer Juliet. She is easy to carry, and lives under my bench, were as Speedy has a trolley to move her around. She has managed 2 adults and a child around Bournemouth's Club track pulling our large 7 1/4" passenger trolley. She makes plenty of steam,and she would pull more if i could add more ballast. See a clip of her below. http://www.youtube.com/watch?v=epAcvROR7XA She was built by a beginner and a bit sloppy in places, but she steams well. She is not any more difficult to drive and fire than the Speedy, although things happy more quickly on a small engine. Hope this helps Will

Thread: Invicta slip eccentrics |
13/06/2013 14:00:00 |
Hi Fizzy Not the best photo, but i show the rear axle (looking from the front of the loco). From what i can remember the levers operate the shaft in from of the axle, these engage and disengage the stops. One each side for forwards and backward motion. Will

Hi Fizzy Invicta eccentric gear could be manually disconnect and the loco set to reversed with out having to push/set the loco back all from the foot plate (see the levers by the drivers knee in the first photo from the link). While it could be made too work i don't know how robust and practical it would be. I am slow building one in 5" gauge, i will have a look for a photo of the back axle, i visited the loco at her resting place in Canterbury Museum. Be aware that there is limited clearance between the axle and bottom of boiler. LBSC Canterbury lamb uses solid eccentric straps due to the limited clearance. Will

Thread: FC3 holder tolerances |
20/11/2012 10:59:25 |
Hi I had the same problem, it turns out that Clarkson make the cutter shanks a couple of thou under the stated size. So you can only use Clarkson FC3 cutters in the holder. I made up a new holder to take the Omega style FC3 cutters which i am now using.

Thread: Clearance for piston and cylinder end cap |
14/05/2012 15:39:37 |
Hello I have been looking for a guide or fomula to calculate the clearance between the piston and the cylinder end caps. I have had no luck in a internet search. The cylinders in question are form the Stuart Turner Victoria 1" bore x 2" stroke, but being using in a vertical boiler steam loco. Any ideas where i might find the imformation?
Thanks
