Hurrah! The valve gear is complete and fitted on both sides. Not that it didn't put up a bit of a fight but I've beaten it into submission (for now).
Despite the usual precautions of cigarette paper washers, dabs of oil, etc., I still managed to solder on of the expansion links solid in it's frame and wreck one of the union links. The expansion link required removal, cleaning up, re-fixing the spacer washers (one has ended up being loose in the reassembly) before re-assembly. Fortunately, I had success second time round.
The union link soldered up solid to the drop link, despite a layer of oiled cigarette paper. Unfortunately, getting the pin out resulted in the link de-laminating and I eventually snapped one of the eyes off one end of one layer whilst trying to remove the remaining bits of pin. As one of the links was already made up from some spare etches I found, after an earlier disaster, there was no replacement part available. As a result, that link is now only the outer layer and no forked joints. I've used brass lace makers pins inserted from the back during the second attempt at assembly. I don't think this arrangement is too obvious on the assembled gear but, obviously, that union link is now rather delicate. I hope it doesn't give trouble in service, otherwise it'll have to be an appeal to see if anyone has some spare etches for the short, forked type links.
Here's the assemble gear mounted to the chassis.
And as far as it's progressed to date.
On with the cosmetic stuff now.
