K-27? lets hope so

Hi Guys,

 Malcom, your question got me curious, so grabbed the book and took a look.
 No stretchers (cross members) between the drive wheels. Seemed odd to my eyes too, but ya have to think Baldwins had it sorted.
 Began thumbing forward and found chapter 9 "The Link Supports and Crosshead Guides" pg141. There's a photo of the finished unit on that page and one of it fitted on pg148. Question answered maybe??

 For those without the book. These supports and guides either side of the engine are mounted to a pair of steel plates. One above and in front of and one behind drive wheel pair No2. They have silver soldered feet which bolt to the tops of the main frames. These should act as cross members. Hope this helps.

 Malcome, latest crop of parts look great, every bit as good as Kozo's in the book. I'd be right chuffed with those.

Hi

They answer my question nicely about stretchers, thank you.

I hope you dont mind but i have downloaded them to look at offline, although never at the skill level to incorporate some of this detail it still wonderful to study and who knows if this one works maybe the next one will be better, especially after seeing some of the k-27 & k-36 models on you tube

thank you very much

Well, now I'm home and have access to my book.  But it looks like you've got the answer to your question.

As Fj45 says, there are several cross members between the two sides of the frame, but none right at the wheels.  The closest cross member seems to be the one that is effectively made by the  Link Supports and Crosshead Guides (Ch 9, pg 141).
