Re: Gateside and Northbridge

Hi Jim, re the push rods for points on an angle. I had this but found that using a bit of spring steel wire for the vertical bit I could keep the rods at right angles to the frame and let the springy bit take up the change of angle. I use the brass bit out of a choc block connector to clamp the wire...

Re: Creative Modelling.

Agreed, if you are going to produce complex objects with a 3D printer, you have to know how best to draw them, and what the printer is capable of printing. If the object is functional, let's say a bogie frame, before you can start you need to understand, how the wheelsets are to be inserted, and how...

Re: Silver.

"Silver" is a difficult paint to work with. If a car isn't white by default, it's silver, why because it's the best colour for masking minor blemishes in the finish of the body. On a model it does a good job of masking the detail, but if you try to apply it more thinly it can look patchy. ...

Re: The final day of steam

Back in the sixties my uncle was a bus driver. He was working a trolley bus route, the outer terminus was outside a well known pub. He and his conductor left the the bus and went for a pint. Two minutes after they should have left the travelling inspector walked in and ordered them back to the depot...

Re: Transition curves

We were taught to do that for ellipses when I did Engineering Drawing nnnnnnnn years ago. Can't remember how you set the pins now. It's one thing that a computer draws far more easily, and as for plotting the offset starting from straight even the demon maths teacher thought it wasn't worth teaching...

Re: UppyDownyRoundyRoundyRailway

As well as back to back, check the end float on the axles, as an old hand in maintaining small mechanisms used to put it, "It'll be OK if you can tell there is some but it's too small to measure" Excessive end float, combined with bogie mounted couplings is a recipe for bogie wheels trying...

Re: Any new skills you have learned?

If we hadn't converted the 2 car+ garage into bedrooms, I could have had my pick of quite respectable machine tools by taking a tour round nearby Redditch, the receivership graveyard of so many small engineering concerns. It got to be standard practice to get the Official Receiver's signature before...

Re: Any new skills you have learned?

The problem I have with lathes is what I know about them is what I learned from my father, as a consequence nothing costing less than a couple of grand meets the minimum spec.

Re: Transition curves

I used to do them by eye, but there's a better way to do them now. Get a tracksetta and decide what radius you want for the centre of the curve. Set the whole length to the tracksetta radius, then leave the guide at the centre of the curve and gently push the ends outwards. You may have to shift the...

Re: Bachmann GWR 4331

I've consulted the book, none of the photos taken in service show any lining at all. It's not possible to determine whether they are black or unlined green. The only photo to have any lining is the official "works grey" one which has lining as per Ben's model, plus a thin line applied to e...

Re: Brass Etched kits

I'm not sure about superglue, but you may succeed with two part epoxy glue. I would imagine you would need to roughen the surfaces to which it was applied. One downside to using superglue even if it works is that it breaks down with heat. Subsequently trying to solder something to the body may well ...

Re: Bachmann GWR 4331

The demise of the GWR happened at around the time that colour film was starting to become available in the UK so your chances of finding an actual photo are pretty slim. I have GWR Locomotives in two volumes I'll have a look, see if there's a lining diagram or any information on the 43xx livery, but...

Re: Bizarre Shortcircuit

The clue may be in the description "reverse then on a different corner its shorts out." My guess would be that part of the wiring is being moved by the rotation of one of the bogies and causing a short circuit. DCC power supplies have a very sensitive detector for short circuits so by the ...

Re: By Passing DCC

If you have no intention of running the loco on DCC and no intention of selling it, you don't need the link to the tender. Two of the wires come from the pickups and two go to the motor. Connect one pickup wire to each motor wire. If the loco runs the wrong way swap them around. You may loose the be...
