Well, the gap in the cross beam was rather more visible than I'd hoped, so thoughts turned as to how to plug it. First, I soldered a length of wire across the gap and then wiggled the cut out section back in place and fixed it. Not a perfect solution, but a couple of 0.2 mm gaps are much less obvious than a 2.5 mm one.

The new axles arrived yesterday, so the replacement wheel-sets were assembled and, after a bit of dressing of the bearing inner faces, fitted into the frames. The cross beams have been fixed and the scoop mechanism completed.

On to the brake gear next, I suppose, then frame and buffer beam overlays and steps.

Thanks Doug.
Not a great rate of progress, partially due to the marvellous weather leading to quite a lot of time out in the back garden. Reading and meals, you understand - gardening isn't my thing.
Anyway, the brake rigging has now been made and fitted, although there's a bit of tidying up still to do to remove excess solder. Assembly was rather fiddly but I'm quite pleased with the outcome. The brake blocks aren't quite as close to the wheels as on DougN's V2 chassis! :mrgreen:

I have run into a small problem with the cosmetic frame overlays and the spring and axlebox castings. Whilst I decide what to do, I thought I'd make a start on the body. To this end, I've assembled the base plate and inner sides/back. The fixing arrangements were altered by use of smaller nuts and screw, as these seemed to suit the etched holes and slots better than those specified in the instructions.
Here's the assembly mounted on the chassis and with the front and back bulkheads just slotted loosely into place.

The frame/casting problem alluded to above is that the spring and axlebox w/m castings have locating pips on the rear, which do not really match up with the holes in the etchings. I've managed to open out the spring locating holes enough to get them to engage, but the axlebox locators appear to be on a slightly different pitch. I've opened the holes for one box (rear on the LHS) to 1.5 mm to suit the pip diameter, but the centres are different, so the box still does not sit down properly. If the holes are opened further, the edges will be visible outside the castings and it is almost impossible to move the holes in the inner chassis frames because the horn guides are right behind them.
I wonder if anyone else has experienced this problem?

The only solution which comes to mind is to file the pips off and simply position the castings by eye.

I was about to go and look for the MRJ articles on the Black 5 and Jubilee builds - but I presume those will have both been done with the older style of underframe?

I'm glad to see the half etched lines to help form the curve in the right place and in the right plane.
