Contrary to my last blog entry, the sand pipes proved not to be the only outstanding work. I realised that I had not represented the drive to the mechanical lubricators. On the Caprottis, this takes the form of a triangular swing link driven by a return crank on the RH driving wheel. Whilst I had provided the mounting bracket under the foot plate, I hadn't really thought out how to represent the mechanism or how to actually fix it to the loco structure. This proved to be rather more testing than I would have wished! Unfortunately, the parts provided by the kit didn't replicate the full size version accurately enough for me, so whilst I did use the drive rod (which I had to lengthen), all the rest was scratch built.
As with my BR Standard Caprotti, I made no attempt to make the final drive to the lubricators work, just the lower part of the swing link.
My initial attempts were quite successful and I had the pivot mounting soldered to the loco bracket and the swing ling made up and pivoted in the mounting. The drive rod was stretched (by combining sections of two of the kit parts. Then things went horribly wrong and I nearly gave up.
In trying to open out the bottom holes in the link, the whole assembly came adrift from the loco. So much for my soldering quality! Well, access for the iron tip was very restricted.
Next, when trying to solder the pivot pin for the rod in the bottom of the swing link, I managed to not only solder the whole lot solid, but the swing link itself partially came apart. Half an hour cooling off was needed before I could face trying to rectify it all and recover the parts.
Needless to say, I was rather more careful the second time.
Anyway, after all that, I have managed to get it all on and working, giving a satisfying waggle of the link as the wheels go round.
Here's a photo of the finished arrangement. If you look closely, you can just make out the splice in the drive rod near the swing link end.

Still got those sand pipes to do. Then it's ready for painting, I think.
