Thanks everybody. :thumb2:

More progress to report.

The inner faces of the bogie frames were sprayed with Alclad 2 Gunmetal (ALC-120):

The same was done with the frames that have already been fitted to the bogies:
HobbyBoss_Dora_Railway_Gun_72_0133.JPG


The wheels were also sprayed with Alclad 2 Gunmetal:

I then started the long, long process of brush-painting the wheel rims with Humbrol H53 Gunmetal:

Finished at last. Talk about needing the patience of a saint! Luckily, I had the Tour de France coverage to keep me company:

That is all for now

Lots of painting yesterday when I used another two tins of H67 Matt Tank Grey!

The four Intermediate Carriers were painted top and bottom:

The eight bogies were painted top and bottom:

The eight remaining bogie frames were done:

I repainted the Loading Ramp top and bottom including the guardrails:

The cradles were given a second coat of Tank Grey and the recoil assemblies were also painted:

The four sets of arms that brace the frames were painted along with some of the ammunition handling equipment:

Here is the first of two frames that was repainted. I have left the top section clear of paint so that I can handle this beast without ruining the paintwork:

Both frames have been done:

The vertical hoist frames weren't forgotten:

And the two sections of the gun barrel weren't left out either:

That is all for now

Like the idea of those plastic containers to keep parts in Dave, much needed in this build .

Thanks John. I originally started with eleven containers but I am down to eight now. Pretty soon this model will be too big to fit in any sort of container:

I fitted the wheels and frames to the sides of the bogies, making sure that the correct frames were put on the right bogies:

The four bogies with timber detailing had their buffer bars glued on:

Excuse the pun but it is now time to get this build back on track after real-life had got in the way of progress. Talking of track, the base consists of nine sections on which two railway lines are laid.

There are a total of 28 sections of track and 48 fishplates:
HobbyBoss_Dora_Railway_Gun_72_0150.JPG


Parts have been removed from the runners and will need a lot of cleaning up, especially the fishplates:
HobbyBoss_Dora_Railway_Gun_72_0151.JPG


Putting the section of track and fishplates to one side, I turned to the base sections. There are seven identical sections plus two end pieces and I started by glueing these onto the larger sections:
HobbyBoss_Dora_Railway_Gun_72_0152.JPG


On the rear side of the joins I glued scrap pieces of plastic card along the join:
HobbyBoss_Dora_Railway_Gun_72_0153.JPG


I then added two more sections to each end and strengthened them too with plastic card:
HobbyBoss_Dora_Railway_Gun_72_0154.JPG


Turning the sections over, I slid some track over the joins to help keep the sections reasonablly level. Getting the unpainted track to slide through the tie downs was really difficult and I will have to resort to a fair amount of fettling in order to get painted track sections through:
HobbyBoss_Dora_Railway_Gun_72_0155.JPG


These sections flex a lot with weight on them and I have been investigating all sorts of ways to stop it. In the end I purchased some wooden 15mm cubes that will be glued to the underside to keep the sections level and will add a couple of wooden battens too. The centre section of the base won't be glued to the other two sections because at over 1.1 metre long it will be a handful to move around.

The sections have been put to one side now in order to let the joins set firmly.

That is all for now

Some neat fixes there the problem Dave . I can just imagine the stress pushing those rails through the tie downs. Bet you were expecting something to either snap or buckle .

Great, the monster gun is back in the room! Good work on the base.
To make it easier to thread the rails, make sure the leading rail edge is thinned a little and lubricate the rail with a couple of drops of water. I think I’d be tempted to paint that bit after assembly. The rail and chairs will be very similar in colour and a pin wash will easily differentiate the two. If you try to paint the rail first it will increase the difficulty in threading the rail, and the paint will probably get rubbed off during assembly anyway…..
