Re: Resistance Soldering

Jol refers to the probe. A new source being needed, the probe has been redesigned and I have one on my bench. The original push-fit collar has been replaced by a threaded collar which gives a more positive grip on the carbon rod. It is now less likely that the collar becomes detached and lost which ...

Re: Resistance Soldering

Paul is quite right, Bernie. There is nothing here that cannot be salvaged and he gives you good advice. Some of those bits are quite delicate so you might find you need to reduce the voltage to solder them and you will not need to keep your foot down for very long. Use less solder! It is surprising...

Tack soldering the small piece to a piece of scrap etch will give you something to hold on to or clamp.

If we can find a table and power point, I will go through the RSU with you, Bernie.

I have been invited to demonstrate resistance soldering for the whole weekend at Scaleforum in September and will have a second unit available for modellers to have a go themselves.

Now we come to the finer work, beginning with the Motion Bracket. There are a number of parts involved, so it would be a good idea to identify them. The main bracket comes in 3 sizes - OO, EM and S4; the rest are universal. The edge parts which go inside, on top and below the G are on the valve gear...

Re: close up photos of GWR tubular signals

The signal at Llangollen is right by a bridge which is how I came to get the close-up images, so line of sight may well be the important factor. You can see the slope up to the bridge in the first photo and the bridge itself in the second one. I have no idea where the box is - I didn't notice it - t...

Re: Dullcoat

I have have just bought some AK 'Ultra Matte Varnish' which is acrylic, not in an aerosol. I have not used it yet (I only bought it last Saturday) but have seen samples and it was . . . properly matt.

Re: Suitable paint for goods vehicles

I am inclined to agree with Martin that it would be far more usual for colours to get lighter through exposure to sunlight and pollutants, rather than darker. The main darkening agents were likely to be mud, smoke and airborne dirt, some of which would wash off in rain. It is clear that there can be...

Suitable paint for goods vehicles

I am diversifying a bit from the GWR and trying to find suitable paint for other companies' freight stock. I would appreciate pointers from people who model companies other than GWR, as to which paints they use. Phoenix are about the only people who specify a company and colour, but as I have many t...

The boiler base went on much as Jeremy has described with a couple of small differences in method. The bases were formed round a brass bar, mine is 9.5mm diameter.

Assembling the cylinders - first, make sure you have the right bits! cylinder_3444crw.jpg I managed to get two S4 parts and two for either EM or OO. The S4 ones are the shortest. Do check you have them all the same length. You only need two of the parts with the rounded end, one for each side. These...

Next come the cylinders. These need thinking through if you are to make life easier later. There are quite a number of parts and more that are going to be fitted, 13 or so plus some tubing.
