Double Crossing

[MR SPOCK]

[align=center]On a section of my railway I wanted a way to release loco's when switching, and also save some track length.

I found a pic of a double crossing or scizzors, it would save about eight foot of track length, then I saw the price!!
I had made a few smaller turnouts before but not 45mm gauge.

I photocopied some drawings from Peter Bunce and pasted them onto a wardrobe door, then stuck a few copperclad sleepers on with wallpaper paste and let it dry for a few days,

I got ready made crossing noses from Peco and started soldering,

I thought that it would take forever but after four hours the first model could use it

after theat I worked all day sunday and got lots done only stopped cos I ran out of sleepers and solder

then I tried it for size cut the gaps and fixed it down to test,

then painted it

well pleased

WOW , that looks very technical

Nice bit of trackwork

 

[MR SPOCK]

[align=center]Its been outside for ten days now and looks like its been there for ever, looking for some nice metal switch stands to finish,
total cost was just under£40 for the bits and nearly four days work,

Hells teeth, now that is a piece of engineering, well done you

 

[Gizzy]

Impressive!

I assume it is all working electrically?

 

[MR SPOCK]

[align=center]It does now, had a few sparks flying, took three atempts to find all the shorts

Hi Mr. Spock,

in Germany, we call that a trousers braces.
Often enough it was combined with cross-switches, what made the difficult mechanics perfect. Like this (but there are better ones)

It looks great your work,
Gratulation!

Back in the old days I used to make that sort of thing in oo gauge... but in G? Nah! I take my hat off to you, it looks terrific!

i thought a lot if i should post this...dont want to critisize. For more, im not sure if i am right.
But i think there is a little mistake in the system (what makes it look not the smallest way worse!)

Look at this:

The guardrails make a bend and ar ending soon. But i think they should go further to the mainrail of the crossway.


I can guess it is just a little trick because of the electrics....!




And: please dont get me wrong, im just curious!




Greetings

Very nice work Mr Spock

[align=center]Funnily enough the other end of the diamond is the same,

When I had finished I looked and noticed I had not put any check rails (wing rails) on the nose at that very point, but taking it along to the club it was pointed out that I had missed its twin at the other end,(thanks Graham Mills)
the two rails are notched at that point as I couldnt work out another way without having lots of bits to solder,
By the time I had stopped I was seeing more than double ,the two sets are the only electrically dead zones, all the rest is live,

thanks for your comment,

[align=center]Trouser braces sounds good,
it was an absorbing project,
be a while before I do some more as need to lay some straight track now,

Sorry for daft question but why doesn't it short accross the copper sleepers?

 

[coyote97]

yeah!
LOL

There are projects that wont end...but they DO, and it looks really fine! It was worth the time!

[align=center]I cut the rails and left a gap where the polarity would mix,

and the copper coating on the sleepers has a groove cut in thro to the fibreglass underneath so creates a seperation it took three goes to get them all as every time I thought i had done another short became known,

if you look very close at the sleepers you can just make out the groove, this was taken while the paint was drying, it has toned down to dull finish

Ahh I see. Amazing skills well done!

 

[whatlep]

A fantastic achievement. Like all the best engineering, it just looks right. One round of applause coming your way....

What an excellent piece of trackwork - well done !
How complex is the wiring ? Which bits have to switch ?


Oh, and while I'm at it, I admit to jealousy on a positively industrial scale
