A couple years ago I was visiting The UHB line  with some other modellers. I came across one of the open containers, "Åpen løftekasse", on a standard gauge wagon at Sørumsand. So I measured it up, took photos and back home I made a 3D drawing of it . This I sent to Shapeways and it came back as a very good model ready for paint. About the model I can say this: All dimensions are correct to scale except:

The two curved beams on top to hold a tarpaulin I originally made correct as L profile. This came out to fragile, so I altered it to a square shape with same dimension. The top beam around is a U shaped steel profile. I made this an U profile also but changed it to rectangular to make it more robust. The distance between the supports for the floor is a guess, I suspect there are a few to many. Originaly there have been doors, I have not included those since I found no pictures showing doors. The brackets for the door I have modelled as square boxes. They are L shaped on the real "kasse". Ears for lifting in the crane is omitted. If you look with mgnifying glasses ,you will find indentions where you can drill holes and use thin wires for a loop, two on each side. 

Color. I have used spray cans from Biltema. One is called Red oxide, the other is a bit more brownish. Se picture. 


 

I have used both. I think the red oxide is very close to the original at Sørumsand. All the steel are greyish black. The interior light warm grey planks.. Al the steel reinforcements ar raised 0.3mm so is not too difficult to paint With a fine brush.

 At Finstdbru there were a large amount of wood piles. This was common in Norway up to the 1960ties. If you scroll back to the airfoto, you will see them in the middle of the picture. Here is a cutout of the larger picture:

 

Last year I started the process of building up to 60 such piles. I use mostly 1mm balsa sheets for the stacked  plancks and 0,5mm balsa for the pitched "roof". There are about 500-700 placks in each pile. Today, at the 21st of dec. 2020, I have built 31 piles, but half of them without "roof" because I have no more 0.5mm sheets of balsa. This thin sheet seems to be difficult to obtain nowadays.

Here is a picture of the real piles at UHB

And her is some of mine 


The real piles at UHB was placed on concrete bases. W have found two types still laying around at the old sawmill places along the railway.

Here is a picture by Christer found at Bjørkelangen:


And here is my  two 3D printed versions:



And here is a test under a pile:

This is the design for the drive unit that will move the wagons on the travers in the "Kassefabrikk". It measures about 25mm cube. Split frame pickup.The brown parts are 3D printed by Shapeways in steel for the weight. The pinkred plates are plastic also printed by Shapeways. The green also plastic by Shapeway. This makes a 3 point compensation for optimal contact and adhesion. To complete is N scale wheels, Exactoscale wormgears and a 6mm gearmotor from Mikroantriebe. To further make it reliable I plan to use a decoder from CT electronic (Tran) and stay alive puffer from Fishermodel.

While most people migled at the nearby beach in the varm sunny summerdays in mid july, I took the opportunity to assemble all the sections of Finstadbru H0e outdoor on the terrasse. For three days and two nights. I was a bit worried of rail buckling in the strong sun, but only a small part by the watertower was affected. probably a week spot anyway, so good to find to be fixed. Rails are code 40 soldered to PCb sleepers. 1 PCB and 3 balsa sleepers gives PCB sleepers ca 3.5cm apart. Works fine. Lenght of rail max 50cm.

I have now finetuned all joints between the sections. I use interscrew nuts and bolts M6. I am now ready to proceed with laying track to the sidings connecting kassefabrikken and later the sawmill to the railway. While having all outdoor in the fine weather, i took the oportunity to take some photos:








Here is a "dronefoto" from the balcony of the entire model incorporating the four old sections

Row 1 from left to right:
Freelance transition section/module to connect to Fremo standard

Row 2 from left to right:
Start of sidings and connection to kassefabrikken

Row 3 from left to right:
Sidings to sawmill - kassefabrikken

Row 4 from left to right:
Field and small creek - sawmill and plankstables - siding and main track + plank stables

Row 5 from left to right:
Pile of sawdust and creek - planing shed - Station building and crocery store

Row 6 from left to right:
Road,field and creek - track, watertower, smal bridge, shed, field with haystacs

Flyfoto of Finstadbru early1950s , look here:

 ....and one more.



Include a couple fotos of the watertower with "Hesjer" for drying of hay.


More to come...

Latest progres on the "Kassefabrikk"
I am now on my way to paneling the facades. I use grey carton 0.3mm. I treat the carton with various greys and some silver. Then I fix it with matte clear laquer. I use a cutterguilliotine with a printed scale on the side for uniform width of each panelboard, (about 1,2mm)

This is the chassis for Pryds, a model in H0e scale of one of the UHB locos. To improve performance I have made som parts to make the chassis compensated.

I materialise have 3D printed in High detail stainless steel the box for making the chassis compensated and the driverods with forkshaped joint. The thickness of the rods are 0.3mm These parts came out fine and fits with very little filing. The 3D printed rods are a bit broader than the original as evident in the pic. This is my fault and is not necessary. I will file the 3D printed down.


Here is the box for compensation in place in the chassis. The axlebushes are pushed together in the middle. There is no filing or milling nesessary on the chassis. Just drop in.
