You can't get me, I'm part of the union ...

This is getting a little silly, now the union link is too short, even though I've made the connecting rod 1mm longer than the drawing :blink:

The combination lever looks a little short too, but I think I can live with this.

 

No way round it, I've got to fabricate two new union links from scratch to the correct length. Not sure if the 2-8-2 link should be longer than a 9F item, but whatever, mine does. I'll tack solder two bits of scrap etch together and make both at the same time then think about fabricating a seperate valve spindle to act off the combination lever.

I'm sure that had these locos actually been built, BR would have tried to use as many standard valve gear components as possible; so the union links would be the same as the Brit/9F/Cl 5. THe answer is that the connecting rods are perhaps still too short?

 

Regarding the combination lever length, it looks as if the top end is a bit too high, perhaps because the etched valve spindle (an extension of the radius rod on the Comet etch) isn't at quite the same slope as the valve chest centre line? THis should correct itself if you use a separate valve spindle, as you mention.
