Re: Chassis kits for CSB

Referring to the last article, it would seem strange carefully designing your suspension and then adding pick-ups which also press downwards on the wheels. I use top-wiper pick-ups where possible because they are less liable to be damaged being hidden and away from fingers. The phosphor bronze wire...

Re: New C&L Crowdfunding Project for P4 Plain Track

There is no target date, nor does it say what one gets for their £150. My only experience of crowd funding was something my wife did for a book where she was promised a copy. The suggested donation was about 10% above the copy retail price which would have been considerably more than the cost of the...

Re: Resistance Soldering

I have had sitting in my 'maturing' box, a packet of two etches and four white metal posts which make up GWR yard gates. This is an old kit which came from Pendon Museum. When I bought them way back in the 1970s, I was rather taken with them but on getting home wondered how on earth I would make the...

David, can I ask, when you go to shows do you wear a name badge? Which 'David', Jim - David B or David T? If David B, then usually yes, Jim, but it does depend on why I am at a show.

Re: Scaleforum 2019

In my view, if Scaleforum changed to something along the lines of a skills day, or something that is smaller, then those who travel long distances will be less likely to come, and there will be fewer traders who will feel it is worth while attending. If that happens then something that I think is i...

Re: Scaleforum 2019

Modelu will be at Railwells but Alan has been cutting down on shows as he has so much else to do, the business going from strength to strength. Eileen's will have a range of the more popular figures but you can still order anything in any size on-line. If there is something particular you want, then...

Fixing the window frames in to the end of the steam railmotor. I have tinned most of the way round these and all along the side nearest the fold (yet to be made) , as Jeremy has done on his build. Because the frames are thin and delicate, I reduced the voltage to 1.5v which slowed the process a litt...

I, too, disagree. Like Will, I have found CSB to be the simplest and most successful way to build a chassis. It does answer the original OP as removing the wheelset is also simple.

Re: Methods for Removable Loco Wheelsets.

The easiest chassis I have made uses CSB where dropping (and replacing) the wheelset is a simple matter of removing (and replacing) the wire spring - no screws. With suspension as simple as this, like Julian, I can see no reason for not using it.

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

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...

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...
