Re: Track for battery/radio control?

Thanks to those who expressed an interest in this. I can report some progress -- plastic rail: http://85a.co.uk/forum/images/emoticons/smile.gif http://85a.co.uk/forum/gallery/2/2_111752_390000000.jpg Quite a long way from a proper BS-95R section, but probably as close as is feasible on home filamen...

Re: Sleeper spacing

Thank you Peter, yes I had spotted that feature in Templot. What I am still not yet certain of is which settings to put into it! Hi Neil, Stuart Hince has written a tutorial on setting up custom rail lengths and sleeper spacings in Templot. It's specifically for the GWR, so just change the numbers ...

Re: 3D printing track

As to evaluating pertinent unknowns before starting a project, I don't see how that could be considered as a negative attitude. I didn't want to indicate any bias by pointing out that I've been supplying plastic based turnouts for the past almost 20 years. But I have always replaced the plastic cro...

Re: 3D printing track

A few things I would suggest are checked out before investing too heavily in printed track. Hi Andy, Why always so negative? No-one is "investing heavily" in 3D printed track. What I'm doing is having a dabble with Templot and my 3D printer to see what it can do. No doubt others are doing...

Re: Track for battery/radio control?

Same thing with 3D-printing, which can we're told be made to make almost anything, but that doesn't mean it's the best solution. IMO rail is one of those things where it isn't. Hi Rod, Whether it's the best solution doesn't really come into it. Almost certainly it isn't. The question is, is it a fe...

Re: Track for battery/radio control?

Thanks all for the comments.

Yes I meant 00 RTR, for track testing. I've looked at the Protocab site, but they do only 0 gauge, and everything on there seems to be marked out of stock. I will improvise something in a permanently-attached wagon for testing purposes.

cheers,

Martin.

Is the technology capable of printing rails with 1:20 inclination, or would it be restricted to vertical? Hi Noel, Yes, it's possible. In fact Templot can already print templates with inclined rail, showing the foot of the rail offset a fraction from the head. Whether it is worth doing is a separat...

Re: Track for battery/radio control?

Trials will be interesting. I suspect that the friction between wheel and rail will be excessive leading to flange climbing problems, especially with flanges anywhere near scale size. Thanks Keith. I was expecting the opposite -- problems with slipping and adhesion? http://85a.co.uk/forum/images/em...

Track for battery/radio control?

Some discussion of Battery/Radio Control systems on page 3 of the latest S4 News (216) today. Such discussions usually mention the elimination of electrical wiring and loco pickup problems, but rarely mention the obvious follow-on -- the rails don't need to be metallic . I'm currently working on cre...

Re: C&L track base

One possible way to fix it is to use SMP Scaleway rail in them. SMP rail is, or at least always used to be, under scale width at 0.8mm, instead of scale 0.92mm. Injection-mouldings shrink with age if not injected at a high enough pressure. Which in turn requires having a moulding machine with suffic...

Hi Julian,

It does show knuckle bends being made, at around 6 minutes 30 seconds in.

Re: Turnout construction - Question here please.

Hopefully Tony or Martin will correct me if this is wrong. Hi Julian, It is difficult to make a symmetrical bend if one side is held in pliers and the other side is made with fingers. The side held in pliers will be dead straight up to the start of the bend. The side held in fingers will be slightl...

It seems to be a common misunderstanding, despite a glance at any photograph of curved pointwork showing otherwise. When switches and cro...

It should not be too difficult to improvise a passing contact, which would be briefly connected by the sweep of a lever in a mechanical lever frame, so as to operated the SEEP (or similar) solenoid as the lever is reversed, and (in the opposite direction) when the lever is restored in the frame.

Is there a convenient but equally reliable way of actuating such a motor from a lever frame? Hi Julian, Well obviously the lever needs some form of electrical switch attached. An SPDT microswitch perhaps, or a home-made on-off contact controlling an SPDT relay. Given that much, this design is a sim...
