Re: Resistance Soldering

I do not have a definitive answer, Michael, though I know one should not leave credit cards or watches near the unit. I have not heard of any other concerns. My RSU is a couple of feet away from me so I would have thought that sufficient. My cards still work! Then there are the magnets one uses on t...

Re: Resistance Soldering

I was at Warminster as well - sorry we did not meet. I did enjoy the show which was a really good get together with some delightful layouts. Answering your questions. First: I agree that putting the 100 o solder with a conventional iron where you have indicated does work well. I have often done this...

Re: Resistance Soldering

If you have not used the RSU with white metal, begin on a low(est) voltage setting. Nothing might happen, in which case go up a notch until you get the result you want. Do not plough in on a medium or high setting or your modelling could end up with tears and a blob of molten white metal. Do not let...

Corrected. The boxes have gone as far as they will go because of the pinpoint bearing referred to in another thread.

Re: Resistance Soldering

You may well be right about the height of the axle boxes. Is the spring usually in contact with the box? I have never thought about this. If so, then it is a simple job to adjust them with the RSU - heat sufficiently to melt the solder and slide the axlebox up a tad (or 'substantial' amount). The sp...

Re: Waisted bearings for Bedford sprung W irons?

2. Find a way of making a slot in the cosmetic axlebox such that it can be fixed to the axleguard (W iron) but still leave freedom for the bearing to move within. I can see that forming a 2mm wide slot for this purpose can be difficult, and that using a drill bit larger than 2mm to create the neces...

Re: Resistance Soldering

It's been a while since I posted about the RSU though the unit has not been idle in the meantime. I was talking to someone at Railex about the technique and they were very sceptical about it's use with white metal.

Re: Waisted bearings for Bedford sprung W irons?

I don't understand why you put in the spacing washer which clearly the unit is not designed for. I have never had any need to use them. Your brake block looks too close to the wheel and will inevitably catch on the wheel when you put the wagon body (weight) on to the unit and the spring deflects. Wi...

Re: Waisted bearings for Bedford sprung W irons?

Yoe can also get them on Ebay . I have not encountered problems with the BB units and the only back-to-back I have been concerned about has been with the wheels, not the units. It is an unfortunate side effect that having to spring the W irons apart to fit the wheels invariably introduces a bit of s...

Re: RAILEX 2019

The lighting levels were poor - a number of units were not working and even more were on reduced luminosity. This did make looking at things more difficult and people had to go to doors and daylight to see some items properly. As layouts had their own lighting, viewing them was not an issue but over...

I would be incredibly happy if I could build a chassis is three hours. I would be happy to build a chassis! Modelling is not about speed, it's about the pleasure of making and creating.

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.

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.
