Should I move over to N gauge?

How do you make dust out of a chinchilla and how many chinchillas would I need? Sounds messy to me! :hmmChinchilla dust is fine for N gauge a lot cheaper than ordinary model shop ballast

Alternatively you go the pet shop and buy the ready made chinchilla dust.

Seriously though, I will look at these options soon(ish) but I do need to make room in the loft first, you've seen what a mess it is up there!

Give that a good leaving alone too. Not as bad as Lima, but the new Farish and Dapol models are better.How about Minitrix? Is this any good?

However, I have a question (or two) which has been covered a thousand times before and I still don't understand all the different answers so maybe if I put my question my own way I'll understand any answers folk are able to offer. Have you guessed what the question is yet? I bet some have. Surprise surprise, it concerns electrofrog points! I've just spent over an hour reading up on this on this forum and the links provided from it too.
I have picked up some really good condition (they look new to me) medium radius electrofrog points, 22 of them for £55 :shock:
Now as far as I can see all that needs doing with these is to put insulated fishplates on both sides of the V. Surely that's it isn't it? There's talk of switches to change polarity etc but I can't for the life of me work out why. To be fair I've only played with a set in front of me and a multi-meter and in theory this should work fine. I will have various droppers on the layout so that won't be a problem. Will someone please tell me, "Yes John, that's all you need to do". If they don't then I'll look again during the day to see if it's a tired mind getting easily confused. I may well regret saying in an earlier post "I am a qualified electrician so if I can't work that out I need shooting", you'll have to supply the gun though. I'm positive that electrically it will work but maybe I'm missing something on the operational side of things, maybe I've missed something with wheels bridging/shorting rails or something.

While this thread mainly refers to 00 , it can be used for N as well http://yourmodelrailway.net/view_topic.php?id=1645&forum_id=6
The story of modifying points for DCC - the process can be used for DC as well - the mod takes away the power routing through blades problems that may & sometimes , does occur.
I suggest you have a read through the Forum index on Points, etc .

So, electrically I am correct but it would seem that some people aren't confident in relying on the contact between rails to pass the power onwards. I can understand that and can now see how to eliminate it. I suppose on new points it's not generally a problem but maybe over time it can be especially if the spring in the point weakens, or have I missed the 'point' here?
I had already been through the link you suggested, thanks. I also read through about a dozen other pages and I think I have been suffering through a bit of information overload to be honest. I suppose if I'm fitting a switch to change the polarity then I could also tap off this to power signals too on each side of the point, that's probably on one of the pages I've read tonight too.
Anyway, it seems a lot clearer now Ron, thanks very much for that and especially for the way you answered each part.

Points not only get weaker springs in time but crap/dirt/ whatever gets between blade & stock rails & funny enough, electricity don't like that ! So providing a switch, overcomes crap/dirt/whatever problems.

I want to get this right first time as I don't want to be taking track up again to fit droppers, switches etc. I will be using SEEP PM-1 motors which have switches on already so half the job will be done for me :cool:

Basically the travel of the point throw bar in N gauge is smaller than that in OO (of course) and the smaller travel only just allows the contacts on each side to be reached. The comment was to loosen the screws holding the SEEP to the base board to allow for a bit more movement.
This comment was posted AFTER I had fitted SEEP PM1's to most of the points on my Henllan station board. As yet I haven't done anything about wiring up the polarity switching but when I do, sometime in the distant future, I'll post up the results.
The only two draw backs that are a personal challenge to me so far are 1) the need to change couplings to allow for shunting without resorting to the hand in the sky and 2) having to retrofit DCC decoders to space limited steam engines.
Problems that can be overcome from what I've read but so far are in my too hard basket.
For the "railway in the landscape" feel they are drawbacks that I can live with.
cheers

Better still - ditch the SEEPs and use Tortoises or Cobalts!

Marty, there won't be any smelly kettles on my layout, just proper trains, blue with yellow ends so I won't have the problem with retro fitting decoders to those :cool:
Couplings aren't a major issue either at present as I only have passenger coaches which will be fixed formations. In time that may change to include wagons too so I'll need to re-visit that when the time comes. I have bought a 'trial kit' of various pieces of setrack, uncouplers, etc for planning purposes so we'll see how things go with those too.
Ian, that appears to make sense to space the point motors off the board to give a bit more flexibility on the operating arm. I'll also look into tortoise and Cobalts (never heard of those) to find out the advantages of those.
Thanks again to everyone who has responded, you've all been a great help :doublethumb

I have had one small re-think and have decided to wire it all up so it can be either DC or DCC. Shouldn't be particularly difficult to do as I did that with the OO version too. A bit more wiring to sidings and a few switches but that's all that's needed.
