Ickenham and District Society of Model Engineers,a company limited by guarantee, was incorporated on 10th September 1999. Registered in England No: 3839364. Website: WWW.IDSME.CO.UK IDSME Members Message Board: http://idsme001.proboards.com Hon. Secretary and Registered Office: David Sexton, 25 Copthall Road East, Ickenham, Uxbridge, Middlesex, UB10 8SD. Ashpan is produced for members of Ickenham and District Society of Model Engineers by Patrick Rollin, 84 Lawrence Drive, Ickenham, Uxbridge, Middlesex, UB10 8RW Email: [email protected] Ashpan Number 101 Cover Story The cover picture this month shows our recently completed post box, located by the entrance gate. Peter Fitch and Peter Pardington are seen here (right) putting the finishing touches to it on Tuesday 25th March. To the left of the post box can be seen the new style of fence which it is hoped will eventually go all round the turntable. Much other work has also been going on over the winter months. In the workshop the big lathe has been converted back to run on a three phase supply. It originally ran on three-phase, but was converted to single phase when we first acquired it. Now that we have installed a three phase converter to supply other machinery in the workshop, the opportunity was taken to convert the lathe back again. -

200 Hp Sentinel Steam Locomotive
200 H.P. SENTINEL STEAM LOCOMOTIVE INSTRUCTION MANUAL Preface In the following pages are set forth a considerable amount of information on the technique of driving and maintaining your Sentinel Locomotive to the best advantage. If the instructions and advice given in this book are carefully followed your Sentinel Locomotive will not fail to give good and faithful service and will no doubt earn the affection of its operators and all those concerned with it, as all good machines should. The object of this book is to help all those connected with the locomotive to give it the best possible treatment so that the locomotive may also give its best in return. In order to give operators full advantage of new developments in the locomotive itself or in repair technique or modifications, we propose to send out Service Bulletins from time to time so that everyone may be fully informed of developments. You are cordially invited to write to us if you experience any difficulties in following any of the instructions given in this book or if you require any additional information on subjects not covered. On receipt of your queries we will fully reply to your questions and if it is of general topical interest we will send out a Service Bulletin on the subject raised. By this method we hope to form a fraternity of Sentinel operators. We have kept the size of this book to reasonable proportions so that it can be carried readily in the pocket. In order to achieve this we have not reproduced detailed drawings for each section as this would increase the size of the book considerably. -

SENTINEL™ High Efficiency, Cast-Iron Gas Boiler
SENTINEL™ High efficiency, cast-iron gas boiler RELIABLE, ECONOMICAL HOME HEATING. SENTINEL™ High efficiency, cast-iron gas boiler The smarter choice for informed homeowners. Enjoy home heating comfort with the extra confidence that an advanced design Sentinel boiler pro- vides. The Sentinel boiler combines the reliability of natural draft and cast-iron construction with the high efficiency performance provided by the Slant/Fin S-Series heat exchanger. A new Sentinel boiler can save 30% or more on fuel bills compared to a typical old boiler operating at 60% efficiency. Reliable natural draft design When the Sentinel boiler is operating, combus- tion air enters the boiler and exhaust is expelled up the chimney by natural draft. No mechanical combustion aids are required for the boiler to attain its high efficiency. Nor does it require the copper fin tubes, water bypass valves or con- densing technologies utilized by some other high-efficiency boilers. With fewer components, there’s less chance of losing your heat because of part failure. High performance heating The Sentinel boiler’s S-Series heat exchanger has for years been a “workhorse” of the heating industry, in boilers chosen by heating contrac- tors for performance and reliability. It’s made of quality cast-iron and assembled with durable metal push nipples. Specially shaped thermal pins promote efficient heat transfer. The boiler heats quickly, sending warmth to radiators throughout your home within moments of your thermostat’s call for heat. The Sentinel boiler is so reliable it comes with a lifetime limited warranty. Intermittent ignition or standing pilot models Enjoy the easy installation and reliable operation that natural draft design provides, plus high efficiency too. -
U DYE WB Yeadon London & North Eastern 1847-1997 Railway Collection
Hull History Centre: W.B. Yeadon London & North Eastern Railway collection U DYE W.B. Yeadon London & North Eastern 1847-1997 Railway collection Historical background: Willie Brayshaw Yeadon was born in Yeadon in the West Riding of Yorkshire on 28 June 1907. After his schooldays, he trained to become a mechanical engineer, and started work with Bradford Dyers, but was unfortunately made redundant in 1930 following the onset of terrible trading conditions. In 1931 he joined JH Fenner Ltd in Hull ('makers of improved beltings'), eventually becoming Sales Manager and then Marketing Manager, until his official retirement in 1972. He died at the age of 89 on 16 January 1997 in Hull Royal Infirmary after a short illness. By then he had become probably the country's leading authority on the London & North Eastern Railway and its locomotives. Indeed, Eric Fry, honorary editor of 'Locomotives of the LNER', writing in the 'Railway Observer' in March 1997, described him as possibly 'the foremost locomotive historian of all time'. Willie Yeadon's earliest railway interest had been the London & North Western Railway, with visits and family holidays to Shap summit and Tebay. On his removal to Hull, however, the London & North Eastern Railway became his main preoccupation, and he was particularly inspired by the development and progress of Sir Nigel Gresley's Pacific class locomotives during the 1930s. He began to collect railway photographs in 1933, and continued his interest after railway nationalisation in 1948. The British Railways modernisation programme undertaken from the mid - 1950s prompted him to investigate and record the history of every LNER locomotive. -

Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (1–300 psi/0.069–20.684 bar; 6.895–2,068.427 kPa), but at pressures above this it is more usual to speak of a steam generator. An industrial boiler, originally used for supplying steam to a stationary steam engine A boiler or steam generator is used wherever a source of steam is required. The form and size depends on the application: mobile steam engines such as steam locomotives, portable engines and steam-powered road vehicles typically use a smaller boiler that forms an integral part of the vehicle; stationary steam engines, industrial installations and power stations will usually have a larger separate steam generating facility connected to the point-of-use by piping.
