Still considering....... I'm up for suggestions!

 

How about a pallet of cast-iron pipe fittings?

 

I found some free STL files which give a good range of threaded and flanged pipes and fittings, ready for 3D printing:

I used them on my layout in an overhead cable gantry:

But I'm sure a pallet of fresh castings (or even rusty ones for recycling or repair) would look good.

Take a look at some 1:1 scale items. I have seen all sorts of bits used as loads many removed from things such as old telephones and household items. I have even used the internals from a 'pull-and-go' toy truck suitably painted.

Reminds me of the late Allan Downes, he used all sorts of real plumbing fittings, especially on that steelworks diorama he built.

Paul Rolley has done several dioramas of chemical plants, using a lot of 'repurposed' packaging containers.

They look great! As they were free, would you mind sharing where you found the stl file from? I fancy printing some of them myself :-)

I don't wish to hijack Giles' thread, but I think they came from Thingiverse here: https://www.thingiverse.com/thing:4444380 and scaled down a lot.

 

If you want more details, let's take it over to the 3D Printing forum.

Slide bars were the next thing to sort. I thought I had some 1mm square NS in stock, but I didn't.... making an opportunity of a problem I decided to mill them from 1mm sheet - and to mill a 'U' shape at the correct spacing to make the job much easier.  These were made, cleaned up and checked....

The bars were assembled with the cylinder end covers  and fitted, ready to be silver soldered to the motion brackets for strength

Of course, with white-metal castings involved, silver-soldering at high temperatures 20mm away would inevitably melt them within a second, so Cool Paste was deployed generously to make sure they stayed safe

All went fine, and the joints were all made with a little torch,  and all the castings were fine......

It will be a coat of paint over this, then refit the axles, and fit Conn rods.
