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.

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.

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.

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,

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.
