Pointing the way...

Greetings.

I have been inspired to have a go at a 3 way point by some of the excellent work in the 2FS forum of late. I took the template from Templot ( I am very much a beginner but managed to cob a solution together).

I constructed the turnout from code 40 and pcb strip using my usual easy method of construction: there are no chairs used. It took a couple of evenings from start to finish, and my test wagon rolls through all roads nicely.

The photo shows how I planned to isolate parts electrically( white marks) and where polarity switching would be needed ( green).

The question is, was my reasoning correct and will it work?

Advice gratefully received.

Many thanks

Chris

Impressive Chris

 

Can't help with the sparks I am afraid but am sure plenty on here who will be able to.

 

The question is, did you build it for fun, is it for a specific layout, or will you build a new layout around it?...It might even be all three of those...:D

The whole of the first crossing should, I think, be bonded together, i.e. V and wing rails. This post and others on the same page should help.

Hi Chris,

 

One of your gaps is not needed, and you need 2 new gaps:

The green area is polarity-switched at the 1st tie-bar AB.

 

The pink area is polarity-switched at the 2nd tie-bar CD.

 

Note that you will also need gaps at the ends of the pink and green rails.

 

regards,

 

Martin.

Hi Pete - mainly for the learning curve, although you then start to think "what can I do with this"?! It is one of a batch of points I've been assembling trying to achieve a better, more reliable standard.

Won't be a new layout as such - I'm still working on Glenfield off and on.

Maybe a small industrial plank for the blue diesels?.

This 3 added pics up top seem to show the settings for the three routes throught the point, as suggested by Martin?

 

Sorry for the crudish illustrations but I hope they are clear enough.

The way I understand things, the point motor which controls the back(A- B ) tiebar will switch the correct polarity to the green section of Martin's diagram; while the second motor will do the same for C-D and the purple section.
