Re: A Highland Miscellany

It is always a good practice to sprue patterns up yourself. That way the cast isn't tempted to put the sprues on 'important' faces. The extra cost at Shapeways is more than compensated by your peace of mind. The benefit may have to be weighed against the components in a group like Mark's competing ...

Re: A Highland Miscellany

We haven’t had an update on the etching and mastering that I have been doing for the signals for a while. Well, I have had both the rapid-prototype masters and etching in. Using the former, I have also had my first set of lost wax casting done – in this case for the lamps and finials. This is what ...

Re: South Pelaw Junction

I decided to print out the Templot plan of the scenic section of the Junction and the enormity of the layout has hit home a little. In the following pics, the 37 is about half way between the 2 bridges that will form the scenic breaks at each end It's the enormity of the mortgage to house the thing...

Re: Gluing wood

Actually, the last original flying example met its end due to incorrectly adjusted SU carburettors, as the fact that a corrective measure had been developed quite early on had been lost from the maintenance procedures. Is this a reference to 'Tilly' Shilling's flow restrictor, the device introduced...

Re: Gluing wood

Apropos the DH Mosquito ... It's certainly why there are no original flying examples left. There is an Australian flying Mosse but that was built from scratch and is actually impregnated with epoxy resin (West system as used in wooden boats these days). If epoxy had been around when the Mosse was b...

Re: Fitting W irons

The prototype buffer height dimension was nominal only. There was a 3 inch (1mm in 4mm scale) allowance for loads, weak springs etc. In addition, while the buffer height is marked on many drawings, we don't know the convention behind the drawing. Does the figure on the drawing represent the unloade...

Re: Width of Gresley Bogies

Golden Age Models are finalising their soon to be released LNER trains - Coronation, Silver Jubilee and 1938 Flying Scotsman - and I'm discussing with them the running gear for P4 versions. I think the wheelsets will be satisfactory but they are planning to widen the bogies to accommodate the P4 wh...
