Good progress has been made but the day ended on a frustrating note - I can't find the 8 countersunk M1 bolts and nuts to mount the deck onto the bridge. As they are metric I hope to buy some replacements tomorrow at the local bricolage. Otherwise the project will stall.

EDIT: I just re-read the instructions which says to use cheesehead bolts and they are included in the kit. For some reason the holes on the top of the deck look as though they are countersunk and that would seem to be logical as the frame sides are.

The bracing angles have now been fitted and most of the extra solder has been removed, so a photo is justified. In a moment.

I also started on the running rails and deck. The instructions say to slide Peco rail joiners onto the rails. Slide? More like brute force is required. I opened up the ends of the joiners and also filed down the rail end and eventually got all 12 fitted, 6 to a rail, equally spaced. The rails are then fitted to the copper clad deck using gauges provided in the kit (which when returned give the owner a rebate of £5). The Peco rail joiners are then soldered to the deck, leaving the rails free to expand and contract. Electrical continuity is provided by each side of the copper clad paxolin.

The photo shows the state of affairs at this point - cleaned up bridge and deck with rails in jigs prior to soldering:

Here's a close up of the deck:

And here is the soldered deck with tank engine and wagon, staged on the MDF drive disk.

Before installing the deck on the bridge I decided to put a blob of solder on each of the bridge's brass bolts. This is because I found the nuts were coming loose from vibration while drilling and sanding.

After five posts I am well pleased with the kit and my handling of it. There is something of a steep learning curve for someone who has only built Peco plastic turntables before and as JeffP has noted, the project is definitely "model engineering". I am also getting to grips with the occasional gaps in the instructions, the project becoming more intuitive as time goes by.
