Re: Best Glue for the job!

Has anyone yet tried the new MIG/AK/Colle 21 black cyano? Since I can't seem to avoid applying oversized blobs of superglue, and hate the white mounds that result when it dries, I'm about to order some (unless anyone tells me its absolute rubbish and i ought to stick with the standard stuff - in wh...

Re: Progress with Slattocks Junction

Here are a few photos, taken several years ago at an exhibition at Laval in north-west France (and some 600 km from my current home in le Luxembourg belge ), of my contribution to "Les croisées de l'étroit", where, although there is some basic contour structuring, much of the 3D nature of ...

Re: LNER concrete platelayers hut

Use a temperature-controlled iron set at 100° above the melting point of the solder (so about 180° is fine) and, with a large mass of white metal to solder, use a big bit, the bigger the better. Then, as you suggest, tack solder first until the whole thing is together - and right - and then fill eac...

Re: Kyle of Lochalsh MPD - track layout

It seems unlikely that a locomotive would have been used to shunt coal wagons into/out of the coal siding itself, but only as far as the mouth of the shed, pinchbars being used for the final/initial reverse shunt - a far more common practice, especially postwar when traders' horses ceased to be read...

Re: A4 points out of 6 chain curves

A more compact turnout, with an easier radius, would be to use a 9ft switch instead of an "A" switch. Those "A" switches are "natural" at 1:7, and hence significantly mismatched at 1:4. Although you say A-4 is a prototypical size, and is in fact included in the REA lis...

Re: A4 points out of 6 chain curves

Based on a problem I recently had with a printer not doing exactly what it should have done, may I suggest that, if possible, you add a scale rule in both x and y directions so the accuracy of the final print can be checked. I do in fact normally do that (for that very reason) when creating drawing...

A4 points out of 6 chain curves

I have recently, for my own purposes, produced prints of right and left hand A4 points out of an approximate 6 chain curve. The prints available on the Society database provided the basis for these prints but hopefully these prints have been corrected to eliminate the printing size problem. The &quo...

Re: Suspension for bogie coaches

One bogie needs to be able to rock up and down along an orthogonal axis to the carriage length, the other bogie needs to be able to rock in any direction - thus effectively giving the carriage "three-point suspension". I am not convinced that any compensation or springing is needed within ...

It certainly looks to me as if the track alignment was changed when the larger turntable was fitted. The "modern" photos are just too far adrift from the 25" OS map for that not to be the case. Really David? - that's very interesting but I can't tell how you can see that. I would hav...

Re: Alan Gibson GER T26 (E4) kit build

While, basically, I agree with Dave Bradwell about the accuracy of "modellers" drawings (and their lack of dimensions), I would point out that works drawings are often erroneous too. In general they represent the draughtsman's (ie the designer's) view of how a locomotive (or other rolling ...

Re: Airfix 48xx with High Level Kits chassis

I have found this sort of variability in lost wax castings in the past which I suspect is a result of the casting process when using alloys. As a consequence I always use a fairly substantial drill - typically 0,9mm (of which I keep a good stock as they match an AGW wire size) - and use solder to fi...

Re: Wormdrive sleeves

0,78 mm sounds suspiciously like 1/32 inch (which I would have described as 0,79 mm), for the US market perhaps. You might just find a 1/16"-1/32" bush and, although 1/16" is closer to 1,6 mm than 1,5 mm, you could probably ream the worm out to allow it to fit.

Re: Motor shorting

Firstly and obviously check that no metal part of the motor casing shorts to either terminal (with the motor removed from the loco). If it does that is probably the source of your problem and is potentially incurable, at least without dismantling the motor. If that isn't the source of the problem, t...

Re: Beer and Buckjumpers

I file little notches across the bottom of the bearing, one for the first, two for the second, etc and then I fill the base slot with paint to indicate left or right (or port or starboard) side - left being red, right green, sailors among you will recognise why. Quickly done and foolproof!

The Southern Region 1956 green, when applied to BR MkI vehicles, had a tendency to go "flat" very quickly. If you see a photo of one looking glossy, it either had been repainted (or revarnished, which was a common SR practice) within the previous few months or had just been through the car...

Re: Locking question for MKII Frame

I do understand that some early GWR frames did not have provision for conditional locking. I think, at least as a generalisation, that that applied to ALL early GWR frames as the GWR chose not to use the supplier who held the patent for conditional locking, and that led to the adoption of distinct ...
