Re: Kemilway TC1 tender chassis

I have a 'construction datasheet', as it is described, for a Kemilway TC1 unit. It's for a Fowler 3,500 gallon LMS standard tender. I assume I may still have the etch, etc, that went with it somewhere but it must be buried deep in the 'squirreled away for a rainy day' department. If it will help, I ...

Re: Width of Gresley Bogies

I would have thought it would pay Golden Age Models to check the availability of relevant drawings at the NRM. The Museum's C&W drawing list for Doncaster includes dwg 831N for a 10' WB compound bolster bogie, which looks as though it may well be for the Silver Jubilee set replacements, even tho...

Re: Help sought to check locking design

Hello, Howard; bit of a hiatus, I’m sorry to say, as I have had to give my hands a break to recover somewhat from repetitive strain injury, and have also been devoting some time to a Nu-Cast GNR tender for the first of my K2’s. I believe I now have a workable locking scheme for my proposed layout, w...

Re: Loco depot ash pits

Here’s an extract from a drawing showing details of the construction of the LNWR new engine shed at Nuneaton. The drawing is undated but must be fairly elderly, judging by the use of bridge rails (or whatever they were called by the LNWR). The detail is of an inspection pit rather than an ash pit bu...

Tim, I'm very pleased with the frame's progress: nice positive action as the lever pins snap into their detents. You're quite right about the Farrant drawing, and I think the absence of any representation of the knuckle in elevation is a drafting error. If the plan view is accurate, part of it ought...
