Is that a type of 3D printed resin brass then?
Without the slide bars, I imagine the crosshead/piston rod has dropped down a bit, but there still looks to be quite and angle between the crosshead slipper and the slide bar mounting bracket, whereas they have to end up parallel. Is that all going to be OK?

I was in a bit of rush posting the picture and forgot to add the dialogue. Duh!
I had a set of Modelu 9f cylinder covers to go on the front, but broke one. So I cut the little sticky out bit off (note non-tech speak!) and used that instead. In the meantime I've ordered replacement cylinder covers from Modelu.
The angle between the piston/crosshead and slidebar should hopefully all tighten up once everything is in place. They've dropped a bit in the picture. This is one of the reasons I have made these assemblies removable, so that I can sort out any alignment issues. We shall see.

Cylinder drain valves from Ragstone.
I'm not sure if I've made a very good job of these, so I've ordered another set to be on the safe side.
I've also been modifying the Ragstone safety valves to fit. They are very nice, as are all the other Ragstone parts I've purchased.
Trial fit:
Rather than try to solder them into place I'll use Milliput. This'll allow me time to adjust their positioning. Also less fiddly.

Milliput didn't work out, so used 5 minute epoxy glue.
Mlliput looks like it bonds onto brass, but really there is only stiction holding it in place. This annoyed me when I found out because I used Milliput on a few parts of my "Nellie" and I will have to re-do them one day. Next time I will try tinning the brass first. I mean, Milliput sticks to steel, lead, wood, plastic, there must be something peculiar about brass.

I've also had a go at making the pony truck pintle.
A brass bearing and some brass strip. It's not pretty, but fills a gap.
The problem now is that it partly obscures the front chassis to body retaining screw/nut.
So, it looks like the cutting torch will be brought out yet again to repostion the retaining nut and make a new crossmember.

I've used Milliput elsewhere and it has proved to be indestructible (as I may have accidentally dropped the Crosti body a couple of times!). Maybe it just depends on how it's being used.

Trial fit of front sandboxes.
And a general shot of the loco which straight away indicates the cab needs some realignment (the side windows appear to slope down a bit).
Still a long way to go though.

More work on the l/h sandboxes.
The r/h sandboxes as supplied in the kit (see below) make no sense to me. I've been studying more pictures and have concluded they should be the same shape and size as the l/h ones. So, it looks like I'll have to make some from plastikard.
