Märklin K track unfortunately is quite standard as far as switches and crossings is concerned.
I need a double crossover on my new layout that cannot be built with the standard track and the relatively narrow centre to centre spacing of 57mm for the wide radius switches.
If you try with standard track you get a spacing of some 120mm.
So I have to custom make one by cutting up four switches.
I did one many years ago, those of you who have seen Wolfgang's layout in Rooi Els may have seen it.
Here is a pic of that one.
-
Had a bit of time on Monday night so got out 4 older switches to start cutting them up to make this crossover.
Laid out before any cutting.
Photo 1
Holding the first two over each other to mark the cut lines. Note that I have used a black permanent marker on the rail heads to so my marks a bit better.
Photo 2
Straight edge just to make sure everything lines up.

First cuts done, fitting nicely.
Photo 1
Taking shape.
Photo 2
Progress so far. Took a piece of plywood to screw the sections down so everything stay straight and lines up.

Stay tuned.

Nice! Keep it up...
-
Awesome stuff..... Love it.....

That's some inpressive work. Nice Job :thumb:
-
Awsome, but where is the rest ?
-
Must find the time to complete it. ::) ;D

There's a lot of time between 10:00 PM and 06:00 AM. :stir:

Aloha,
oops been more than 2 years since I have done anything to this crossover. :-[
Well I might need it soon, so after making a bit of space on my table this is the current
project.
First I had to repost the photos as they had disappeared. :-\
Last night and today a few parts have been made and added.
More to follow soon.
-
Nice.......
-
Some more progress.
1st photo, I have done the inside guide rails. (Black arrow)
I have started on the four side inside guide, still needs quite a bit of filing and then soldering before I can fit it. ( Red arrow)
I have also started the four outside guide rails, still need some trimming and bending of the ends. ( Green arrow)
2nd photo just a different angle.

Looking good J!
Sorry about the pics. Were they ona host site or direct? I have not removed any pictures yet.
Let me know if I need to look at something...
-
Hi Ed,
these where still photos that I had on photo bucket.
So I had to remove all the links and then reload the photos.
-
Ah yes. Stupid photo bucket.... :rant:
-
Aloha,
little by little the work progresses.
I have a small sanding attachment with a flat base where I can glue on some sandpaper.
Fine sand paper and into the drill press, then set the height that it just touches the rail tops.
This way I could get all the rail tops nice and level. :thumb:
-
Now all that needs to be done are some finishing touches and then the centre studs.
Then some rust brown on the rails.
Quick photo outside in the sunlight.

Nice! :thumb: :thumb:

WOW, Awesome Jörg.
Came out extremely good...... :thumb: :biggrin:
-
Hello Joerg!
Well done! - But it will not work from all sides! Look the way from the bottom right to the top left. In the crossing it will be a classic derailing point :o. Control the way...
But anyway - enjoy the x-mas day!
Cheers

:biggrin:
Spent some time over the last few days to fit the centre studs.
Tonight first test under power.
Loco drove straight through the crossing without stopping or derailing in both directions. :thumb: :thumb: :thumb:
Still needs a bit of work, but getting there.
-
Awesome..... Great Job..... :thumb:
-
Lot of work, nice result!

Update.
Custom double crossover V.2
The more I looked at the crossover the less I liked it.
So I have decided to try again.
This time I am using pc board strips for the missing tie in the middle.
This allows me to solder the track instead of gluing everything.
I also made a print out of the tie spacing and fitted this under the project to help me line everything up a bit better.
Pic 1.
Pic 2. shows the first two pc ties fitted and the first tracks soldered into position.

Looking along the tracks.

Two more ties in place and soldered.

Nice Jörg! The first one was for tasting. ;)
Looking very good! :biggrin:
Ciao

Super!!!
-
Nice......
Will most probably works better for the power too if I have to guess.....

Yes to good, discovered that I have a dead short in the crossover. :lamer: :bluduh: :rant: :blech:
So I have to start cutting it apart again.
-
I guess you shouldn't have scrapped version 1 !
Steve :stir:
-
Found the short tonight. :thumb:
So work will continue.
-
Oops no update for a while,
I have been figuring out how to cut the track at an accurate angle for the small pieces in the actual crossing.
I have tried with my disc sander, but found it very tricky to get the angle that was needed, was a case of trying and discarding
the track.
There is a rotary table available for my Proxxon milling machine which should allow accurate angles, but that is a few Thousand rand. :blech:
So now I came up with the idea of milling a slot at the correct angle into a piece of wood and then clamping the rail to be cut into this slot.
Pic 1. milling the wood.
Pic 2. angle cutting with the drum sander
-
Holding the first piece of rail in place to check for fit.

Nice...... Clever idea...... Track looks good :thumb:
-
Nice Jörg! :thumb: :biggrin:

Clever jigs :thumb:

Hi everybody,
I have done the crossing tracks.
I have made a little clamp that is screwed into the wood base so that I can take my time to correctly
align the track before I solder it in place.
No more guessing and hope for the best.
Pic 1 shows the clamp holding the last of the four crossing tracks.
Pic 2 sanding everything nice and smooth.
-
After washing the crossing with soap and water, scrubbing with a tooth brush to get
rid of the acidic solder flux I took some photos in the sun after it dried.
Looking along the track.
My test bogie runs through smoothly. :thumb:
This crossover definitely is more accurate than the previous one.
-
I now need to sand some of the excess solder off.
Then i wanted to buy some angle polystyrene at Clowns Hobbies this morning to make the guard rails on the inside of the diamond, shop closed. :eek:
Drove up to Speed models on Durban Road, sorry we don't stock that, go to Model Railroad Specialist in Plumstead.
They gave me the cell number of Clowns Hobbies owner.
So I phoned him, he now operates as a online shop.
Have placed an order.
-
The joy of modelling. ;)
However Jörg, awesome job so far. Not many will tackle this. Well done! :thumb: :thumb:
Ciao

Wow looks great Jörg.
Yea, Wessie, Clowns, had to sell the store :(
But he does operate online only now and will help where he can.
I'm looking for 1.5mm Piano wire now, and it is becomming quite a mission.
Cheers,
Evert

Hi there,
more progress.
I made up the guard rails from strip styrene last night.
Here is the result.
Pic 1
Pic 2 I applied a light coat of primer.
-
Then it was time to make up the center studs.
Pic 1
Pic 2, all in place from the underside.
Pic 3, cleaned and painted the underside.
Yes it has been checked for shorts and I am getting power to all sections. :thumb:
Planned for later air brush brown paint to finish it off.
-
Okay I have now also air brushed the top side with matt brown.
Provisionally cleaned the rail tops, now I will let this dry for a day or two and then do the rust paint
on the sides of the rails.
Then comes a second round of testing.
-
Stunning Jörg! :eek: :thumb:
-
WOW, that is really looking GREAT......
Can't wait to see ti in action. :biggrin:
Awesome job Jörg :thumb:

Amazing work!!
