How to make : An Inexpensive Powered Railer/Re-railer
« on: September 20, 2017, 03:42:50 PM »
(Prolog : To avoid confusion:- the (now new) first two posts have been attached from another topic, the original start of this "How to " is now two posts below , , , )

Your wish is my command,,, but I think this is more in the "make believe " side of "making it up" :) >  just by way of thanks for a fun afternoon of reading good ideas/tips on the forum have a giggle at my prototype below !
Thoughts so far : aly strip would lift the wheels too high as the guide in the Farish Peco plastic is very shallow, sticky back copper tape perhaps also too thick - remains to be seen, and the kitchen foil whilst an amusing heathrobinson may not be durable enough long term? So then a purpose (re)built block would be required and thus simpler to buy the proper job !
PS croc clips just parked there as I only have two hands  and no third to operate the camera lol!

How to make : An inexpensive Powered Re-railer
« Reply #2 on: September 20, 2017, 07:27:23 PM »
In order not to disrupt the powered railer/re-railer review topic
http://www.ngaugeforum.co.uk/SMFN/index.php?topic=38654.msg465476#msg465476

and @scotsoft 's request for construction/pictures of a DIY job.

Here is my Mk2 prototype built with a Peco railer (the Mk1 was a feasibility study, for want of a better name!)  :-
the Mk1 showed that kitchen foil was well conductive and up for this simple job. Two narrow strips of foil were cut long enough to wrap round the ends and proved good enough to do the elerctrickery pick up and amazingly did not even require glue to hold in place ! (When I get another Peco I'll make a more permanent Mk3 but I didnt want to mess up this the only one I have :) )



delightfully entertaining and dare I say even more effective than my fumbling fingers pushing. Hugely entertained my wife when she found out what I had been doing this afternoon, caused quite a laugh with much BluePeter refs :)  !

tested on Farish :- Jinty, 4F, J39, 5MT and Duchess,  all run off sweetly. The first three also reverse back on perfectly but the 5MT and Duchess do not, first thoughts are that the slope is too great for the long wheelbase and they slip. A bit odd as there is no hesitation when running down off. So more tinkering to be done.

This is only what I have done for myself, I am not suggesting anyone else etc&etc ! as is the fashion to say these days. Because I have been thinking "what could go wrong" : the kitchen foil is flimsy and could maybe shed a bit that could foul the mechanism ? but is cheap to replace before becoming distressed. If glued down then the wrong type of glue could sticky up the wheels maybe. Finally when reversing back up enthusiastically it can easily run full tilt off the back end,  eeek ! nearly lol ! So deffo needs a bufferstop !!

So for those of a nervous disposition:  stay with a proper job designed and built by current engineers from a reliable merchant. Not by a retired engineer with nothing better to do than have a bit of a frolic one afternoon  ;D

Anyone think of any more pitfalls for the unwary ?

It's one of those things where you look at it and say "why didn't anyone make one of these earlier?"

I'd have thought heavy duty "roasting" foil and a sensible adhesive would do the job.

Top marks bloke.

Like the idea of heavy duty foil, good one, will have to go on a 'foil grading tour' of the domestic quarters tomorrow.

Another from the elfinsafety executive: if unglued the underside bits of the foil strips can easily move sideways and short the controller (dont ask!), but I expect these days they should all be protected anyway ??

Great idea, thanks.
I have just done the modification on mine and it works perfectly.
It is also sort of satisfying to watch the locomotive drive itself off the ramp and proceed on its way.

I used adhesive backed aluminium foil tape, that is sold primarily for shielding electronic housings.
Fortunately, it is just a few mm wider than the re-railer, so I just rubbed it down and smooth with a tooth pick and then trimmed the surplus.

One thing I think important for a good result...the Peco re-railer is quite a snug fit over the rails at the transition end.  I think excess tape here would stop it aligning snugly, so for the tape that folds under to make rail contact, I trimmed off all but the narrow strip that makes rail contact - a bit fiddly but worth the effort.

Again, thanks OP.

Cheers, Tom.

Edit:  Oooops, I see there are 2 threads running on this, and the other thread is dedicated to 'local modification' - I should have posted there, sorry.

Depends if you fancy being sued by Proses (assuming they've patented it).
