Best wishes to everyone for the festive season and a safe new year. My frames are now complete and stayed. The 'rear' section is massive/massively braced but the front extension frames look puny by comparison - it's no wonder they got bent from heavy shunting and I can't imagine that the two struts between the smokebox and the buffer beam added a great deal strengthwise. I've read about Churchward's fascination with American locomotive split saddle/smokebox design but can't understand why his following CMEs persisted with the practice and it wasn't until 1944 that Hawkesworth made the change to plate-framed Halls. The four cylinder engines and inside cylinder were plate frame 'from the word go' so it wasn't as if the GWR had no experience with that method of construction. My extension frames would flex (slightly) from side to side when the buffer beam drag box was bolted to them but yesterday I made and fitted the stay for the front pony guide block and the flexing stopped. I think that our little L-Ps are stiffer than the full-size and we won't have to worry about damage in operation. Just my own thoughts and questions; has anyone else thought the same? Apologies if the preceding paragraph is 'off-piste' but having the thing together on the bench made me think.

Happy Christmas from me too!  I'm sure your front end will be fine. Any pictures?

Got all my bits out over the last week and have cleaned up the front wheels. Rear wheels got their first turning today and are cleaning up nicely. The only way is carbide grit files and tile rod saws!! Discovered another builder 10 mins walk away?? Merry Christmas to all!!

Hi chaps I have been building my prarie since 2008. During the time I have built and completed a Ken Swan Wren 7 1/4" that I currently operate at our local club. I am now back on the prarie case so to speak and I am very close to a trial on air. I estimate about 6 weeks away. Lots of detail work complete including boiler built and certificated. I have been visiting this site for some time but haven't seen a lot of movement..

Hi bmwbob, good to hear of your progress, keep us posted. Santa brought me a really nice book about the GWR prairies and Moguls. I didn't realise I'd been such a good boy all year!
