CAD Drawings

I began with creating a drawing using some CAD software. I needed to produce an accurate drawing to work from, in order to build these very intricate frameworks. I took the Time Machine control console and used a set of callipers to get the correct measurements. My good friend Ed Turner supplied me with a set of measurements; these measurements were for some LED's to be used on the kit in question. The measurements were very much the same as Lunar's resin bulbs, so my CAD drawings were based on Ed's information.

Measurements called out here are for the Lunar Models scale
After I completed the drawing of the console cages, it was also necessary to produce a drawing of the base of the cages. Each base has eight connection points, and I used the CAD software to draw this. I finally drew the side view of the cage and it's half section. (See Fig 1)

Next I printed out the drawings to work form on some good quality paper. I then printed out the base section of the drawing on some general sticky labels (See Fig 2) Three of these were required.

Base & Wire Construction

I used a material called plastic-card for the base of the cages (See Fig 3). It can be obtained for most models shops. I found it was very important to make the each base the same in height. The Plactic-card I used was a little under 1mm thick, so I sanded the card until it measured about 0.75mm. I then placed the design printed on the sticky label on the plastic-card, and then cut it out to the circle. I then had to sand this to take out any cutting errors and I then filed this to give a correct circle. After I was happy with this I needed to bend the wire frames to the CAD drawing. The wire I used was some brass coloured wire supplied with the Lunar kit. I then stretched this wire in order to take out any kinks (See Fig 4)

The next stage was to find a former to bend the main cage frames. I found some nice plastic rod in a local model shop, with a diameter of approx 5mm. This was ideal for the job. I then proceeded to bend all the cage frames on this former (See Fig 5&6).

After bending all the frames it was necessary to trim them all the the exact same height. I used my CAD drawing here on the side view of the cage frame, the height measured approx 7.33mm, this can be changed depending on the size of lamp you use, but I think this measurement is good for the Lunar kit.

After the cage frames were completed I began cutting out the notches in the base, eight of these are required and each cut needs to be the same depth. I used a very shape knife for this; in fact it was a surgical scalpel. When I was happy with this I began laying in the frames, starting with the whole side frame, all the other wires are in half segments. I assembled the whole frame at a right angle to the way I looked at the base, the next two segments go in at a right angles to the main frame and the remaining sections attach at 45 degrees (See Fig. 7) I found a pair of tweezers very handy for this operation.

Here is an idea which Martin agrees would make the above step easier and more accurate. Drill holes where the frames go before trimming the circle. This will make a neater appearence and the frames will fit exactly.

It is necessary to cut all the segments to the exact same size before you begin to glue these in place. It's also a good idea to cut a set of frames and test fit them and then cut the rest to match these. I used a gel type Super Glue to fix the wire frames to the plastic base.

Fig 9 shows the completed cages, and the cages test fitted to the control console (Fig 11).
