DS9

So, the last episode was left with a third of a CradBog (Cradley Bogie), car awaiting it’s chassis, and that is exactly where it still is! The chassis is still firmly in firmly locked down Wales and as this particular body was only meant to be a test… In the spirit of testing we decided that we also needed a four wheel car as we have absolutely no idea what radius of curve these will be happy with at the totally non regulation gauge of 24.5mm. With justification in mind a start was made on a DS9 car.

 

Again, the plans came from Terry Russell Trams which is a useful resource for such things. Unfortunately I am a little short of pictures of the initial construction as I just got on with it, building on the lessons learnt with the CradBog. Again I took the profile of the side and turned it into a rib in PhotoShop and printed off several to use as patterns. Much time was saved by soldering together a set of blanks for each side, then a copy of the profile was stuck to this sandwich with double sided tape and this was then set about with chain drilling, a fret saw and files. Once shaped to the correct outlne it was un-soldered to give a perfect set of ribs. These were then assembled onto a flat side which was again double sided sticky taped over the plans for accuracy. An outer skin of 10 thou N/S was then soldered over the top making good use of the resistance soldering iron which made it possible to press the curve into place with the iron in contact.

The window frames are brass unequal U channel soldered over the ribs again building up over the plan. The panel beading was added with various rod with the rather unusual ogee waist line made up of a 1mm and then an.6mm above. Unfortunately I only had brass I the larger diameter and the differential expansion ‘ contraction with the N/S has caused some warping to the side but I will settle for ‘adding character’ this time.

 

The drop lights were a bit of a problem but I eventually hit on the idea of using slivers of rectangular brass section cut very accurately on the mini chop saw. With spacing pieces between the pairs this provided a very neat solution.

A basic floor was soon added and attention was then turned to the partition. Again, a pattern was made from the plans a sandwich of metal ensures identical part with much reduced file work. Unfortunately the work with these parts is increased as they are double sided.

With the partition in place floor strips were added with strip cut on the guillotine and soldered in place with the resistance unit. You might notice the large gaps in lower part of the window frames – these are to accommodate the glazing which I intend to use glass microscope slides for – eventually!

The chassis for this is coming along nicely in Wales and there should be pics of it in the next thrilling episode.

 

Incidentally, there is a bit of a problem if you try to look up 'DS9' - Dudley & Stourbridge class 9 - all you get is the Star Trek spin off Deep Space Nine and what is more this also features a rapid transport system so 'tram' get you nowhere useful!
