Feldbahnmodule with ship

Very cool!

[Bill Gill]

Very good progress, excellent work. You didn't lose any skills even though you had to stop modeling for awhile.
All the metal work impresses me a lot!

It's been a while since I wrote (28.11.2016):

The upper metal end of the sluice walls will arise from 10.0mm x 8.0mm brass profile.

Since then, the brass profiles slumbered half finished milled in a small box deep in a drawer and came only at cleaning up again to light.   

Recently, the last upper curves were milled at the edges with a 1.25mm quarter-end mill.
Then the small Böhler-saw was used and brought 45° miter to  the first profiles.

Thereafter, three 1.0mm holes were drilled vertically at the ends and in the center to precisely align everything with small pins on the MDF masonry and also to secure everything in gluing later.

Gradually, the parts are positioned on the upper edges of the lock walls on a trial basis.

Meanwhile, all brass profiles for the upper left edge are mitred ...

... and tentatively placed.

A small milled subframe helped to solder the small brass profiles around the ladder.

Next, the round edge will be profiled from a 10mm brass plate.

For this, the order for each surface milling passes was set in the CAD program.

Now the mill machine has to come into action.

As always, it is a pleasure to follow along with your progress on this project!

The precision and execution are beyond comprehension. -- Russ

[fspg2]

Thanks for your consent.

It took less than an hour for the milling machine to mill the round metal edge.

Wonderful work, I also do a lot of machining and I really appreciate all your posts. I do not post much but I find all your work amazing.

[Hydrostat]

How are you going to achieve the butt joints?

[Bill Gill]

Always enjoy seeing your work.

[Barney]

Amazing just amazing - such precision

@Volker
I can´t give a clear answer to that. On all the pictures I know, I´m not been able to see any clear joints.... except here:

The photo is from 1959 and shows another area of the lock.


I will not solder all the brass profiles to each other so that the wood and brass parts can "move" when the temperature changes.



Now the first metal edges were placed on the wall.

Previously I have glued into the holes 1.0mm brass wire with shaft-hub joint-adhesive and sanded the tops smooth.
On the bottom the wire stopped about 5 mm long for precise assembly.
The parts were blasted and blackened.

Something to the ladders:

In July 2011, I had milled a gauge from Pertinax to build the two ladders for the locks walls.

what´s that? (fspg2)



The 1.0 x 2.0 mm thick model spars are 20.0 cm (17 steps) and 28.0 cm (24 steps) long and 20.28 mm wide. The soldering gauge heIps for clean aligned stairs.

After the protruding rungs outwards on both sides were cutted with an 0.3mm saw blade on my Böhler-saw
(similar to how here), I had smoothed the outside with a sandpaper file.

Afterthen the two ladders were sandblasted.

Four 1.0 mm holes in the wall pick up the pins at the ends of the brackets.

Now I would like to thank all of you for your participation - but especially at Russ for the opportunity to write here in this great forum!

Have a good start for 2019!

[finescalerr]

Everything looks perfect. I find no room for improvement. Satisfactory. -- Russ

[Ray Dunakin]

Once again a well-made jig proves its worth!

[fspg2]

I could do only a little "earthworks" the last days.

So I installed the mooring first and glued the top metal edges.

A few plywood boards were installed for reinforcement.

For soundproofing, I had filled up all voids with cellulose insulation still present.

great, what is the sound insulation for?
