I have to admit progress has been slow this week. What with sidetracks into CAD, changing my mind about using CAD, and other conundrums, I finally sat down today and set about the buffer beams.
My plan was to replace the cast whitemetal buffer beams, which have integrally cast buffer housings, with fabricated ones from scrap etch. I'd already drawn up the essential details, as you may recall in an earlier post. I started to mark things out, and then decided I was on the wrong track.
Instead, I opted to modify the existing castings. Various things are in favour of this route, not least the large fixings and depth of the beam itself.
On the right is the original, that on the left after I've been at it. Essentially, I chopped off the cast housings, drilled out to accept the brass versions, replaced the brackets and coupling reinforcement, and added lamp brackets.
The second attempt, I managed to retain the cast brackets and coupling reinforcement plate, which speeded up things a good deal.
Here's the first one, again. The holes at the rear are for the assembly bolts. The kit was designed to break down into three main components for ease of painting - floor/underframe, body, roof.
I've been studying the photos again, and I think I've worked out where the various pipes go, which will be sorted out quite soon. I hadn't noticed before, but there doesn't appear to be a steam heating pipe at the driving end: presumably it was terminated in the guard's compartment during the conversion process.
The driving cab windows ought not to have those inserts, so they'll be coming out soon. I also need to relocate the body end lamp bracket, and provide it with a companion. Oh, and refix that cant rail etched strip.
Here's the driving end from underneath. The buffers haven't been fitted properly yet, just positioned for the photos. I need to concoct a workable springing system for them. A conventional coupling spring has been used, and a small brass wire hook added to allow the coupling to be hitched up under the buffer beam in a prototypical fashion if required. The buffer beam castings have been glued to the floor plate, and the bolt heads you can see pass through both to the captive nuts in the end of the body.
Here's the other end of the coach, showing the simpler modifications to the buffer beam casting I shall use from now on. I have decided that I shall fit the passenger communication gear to this end of the driving trailer. I haven't found evidence that it wasn't fitted, nor have I found any to the contrary, so I shall fit it anyway. It'll add to the clutter on the ends nicely.
Inside the driving cab end, you can see the bolts that hold the body to the underframe. The floor is 1mm thick styrene sheet.
I found a load of castings in one of our many bits boxes, which I think were intended for these kits. They must have been separated out at some stage, only to have been forgotten about when the coaches were sold on to their new owner. You can just make out the daylight behind the hinges. Hinges are formed from a folded etched part, inserted through the holes in the body from inside the coach. I'll need to fill the holes, even though the interior ought to cover the gaps.
Finally, a quick view of the body reunited with the underframe for a spell. While I ponder further on the interior, and fitting the various pipes to the ends, and how to fit the roof - which will not be trivial, which will become apparent later - I may turn my attention to detailing the bogies, fitting them to the floor, and adding final brake linkage bits to the underframe.
