Good golly Miss Molly ... and this is just the beginning! -- Russ

The four side bridges also need handrails.

An assembly jig is again used to assemble the individual railing sections at right angles.

The small 0.8 mm rivets aligned all parts precisely in the corresponding 0.9 mm holes in the Pertinax template when soldering the pre-tinned L-profiles.

The lower 2.5 mm x 2.5 mm L-profile shown in light green in Figure (Träger-Montage 133 ) was given 3.0 mm wide cut-outs in another Pertinax template.

In the original bridge, slotted holes were provided between the railings of the secondary bridges and the first vertical supports on the bridgeheads to compensate for temperature-related length differences.

Although they are shown in the model, they have no function - the temperature expansions will certainly be limited here  

Small brackets (2.0mm x 0.4mm - side length 6.5mm) will connect the side bridge to the fixed railing on the bridge heads (as in the prototype). The small brackets are only soldered to the vertical supports.   
In my model replica, the handrails (drawn in red and green) are placed on the two protruding rivet heads of the small brackets and thus serve to align the handrails.
This will make it easy to remove the side bridges.

The end pieces of the handrails are bent. In the model, I would have had to bend the 2.5mm x 2.5mm L-profile with an outer radius of 12.0mm.
An attempt to bend an annealed offcut ended up in the scrap.

I then obtained two left and two right parts from a 3.0mm thick MS58 flat profile.

As I currently have to wait for the next 2.5mm x 2.5mmL profiles to be delivered, the 8.0mm x 5.8mm wooden beams that were sawn from a 20mm x 10mm beechwood strip back in 2014 were...

...with a rotating wire brush on the pillar drill. This left me with some signs of ageing in the rather hard beech planks.

After an initial bluing with gray-brown wood stain, the parts have already been loaded for testing and are waiting to be transported to the bridge....

It's good to see you back at work on the model. -- Russ

Thanks guys for your comments. Here's two photo of my progress. The frame,front axle assembly. and most of the steering assembly. Next working on parts of the cab and masking off were the engine attaches to the boiler and frame. so I can paint the boiler and frame before adding more parts.(sorry for the quality of the two photos the next photos will be better)

Thanks Barney.  It's all perfectly clear to me now, you're just a mechanical genius!

If its read-able the basics of a trommel

The principle of trammels are the same even for modern types The ore is passed through a rotating tube which has graded grids on them and then water is pumped over the ore under high pressure or more like a "raging torrent"
the fine graded ore pass over filter beds and the gold sinks to the bottom thick matts are often used as well as the grids some of the ore grids use vibration as well as the high pressure water - managed to get some early and late brochures from companies like Dove who make quite modern versions there are some early UTUBE versions of trammels in action and Dove have some superb photos of later versions
The early contraption I posted at the start is actually a mine head but its just the look of it that gave me inspiration. 

Amazing work. But how in the world were you able to come up with such incredible detail with only those few rustic photographs you posted at the beginning of your thread?

Humbrol enamel Undercoat / primer coats on - now getting ready for a bit of colour what else "but green"
hope to achieve a reconditioned look in its early days but well looked after with a oily rag look 
Barney

Very Nice - its nice to see models in a well kept state and looked after but with some signs of wear and tear. I do like weathered models but a lot appear to be over the top and unliveable in the case of many model buildings - well that's my view - but saying all that Russ "most satisfactory"
