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:

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

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.
This is 3D printed parts for a very small and heavy drive unit for moving wagons on the travers. There will be one on each track. The two on the upper left are from I materialise and the two upper right from Shapeways. Material is blackened stainless steel. They have schrinked about 4-5% which gives me problems. Also they are a bit out of square shape. Shapeways are best here. I found the steel to be quite hard and I had problem to cut threads for 1.2mm screws. One solution is to 3D print a larger hole and pressfit a brass tube into it. Then making threads in brass is easy
 Here Is the travers with with 3D printed guides, fixture for holding the gearmotor and the servos for the sliding doors. There is also two servos hidden under the plywood plate on the far end
I use micro switches and diodes to stop the travers at each end. The round milk caps will have off center screws to fix them at the right spot to stop the travers at the correct position.

 H0e and Z scale Mini Meet

In the weekend 17-18 nov. 2018 a Mini Meet was held in Oslo arranged by Hans Henrik Riddervold.
He is the man behind The UHB rolling stock from 1994-96 and later a wast development of american Z zcale through AZL (American Z Line). Participants were Svein Martin Holt , Tor-Jørgen Moskaug (Torsja) from Norway and the german modeller Karl Sinn all with Small Z scale dioramas. Also from Norway Tertittkameratene with their Fremo modules/sections. ( Knut E. Kittelsen and Christer Ritterberg with Stein R. Pünther)

Here is a link to Svein Martins fine pictures from the Mini Meet:

The work with Finstadbru stasjon and sawmill area is  progressing. All the woodwork to the sections are made. All parts are cut after my drawings at a commercial woodworking firm utilising a CNC Mill
It was costly but valuable. Here is two pictures of the test assembly in oktober:

Finstadbru Kassefabrikk (Crate factory)

 Referring to the  Air photo of Finstadbru , the building is to the left towards bottom. To aid in the constucting of the model I use the air photo (ca 1954), older maps of the area (the footprint) and a photo from Digital Museum  At the back in the photo 
Thats about all I have, but I think the size and form will be reasonable correct. Another photo in Digital Museum from ca 1955 show the then newly built saw building with a siding for UHB
Sidesporet til C.H.Aanerud sag og høvleri på Finstadbru er ferdig.
This building also shows in the air photo at middle bottom.

This gave me the idea to make a play wit empty and full wagons in and out of the two buildings.
They are about equal in foot print.  This will make more interesting trafic in Fremo context.

For each building I reserve a space in the middle that can hold 2x3 bogie flats on a travers with two tracks, one for empties and one for loaded wagons. On the end nearest the siding and connected to it, there will be a room for one wagon, loaded or empty. On the other side some interior vill be visible through openings and windows.

Here is the model of the Kassefabrikk so far:

Mork meieri

 Christer wanted this building for a small siding at one of his modules. It is a Funkis inspired building near Mork station on UHB. it was built about 1938. Here is some info of the building:
 Mork meieri The building still stands in a somewhat changed form.

So I have used a lot of time to find out how it looked originally and here is the result so far on paper. It is now ready for 3D printing (another heavy task).
