Group 1 the framework

Parts list

The Base plate (1.1) must be rectangular and all corners and edges should be worked over using a fine file and emery. Make sure that all positions of the attachment holes fits together with the corresponding counterparts, the ground plates (2.2) (5.2) and the crown plate (1.3). For this work, the counterparts should be temporarily fixed in position and the holes drilled right through both components.

The Pillars (1.2) are made each from three pieces, a brass rod of 8mm dia, to which both ornamented portions are soldered. If you are lucky enough to have a lathe with a swivelling slide, the lower conical part can be easily produced by swinging the slide over to the half angle of the conical part. If not, there is another possibility - to turn it in small steps and finish it using a file and emery. The decorative profiles can be made either using a form tool or again using a file and emery. Most dimensions are not critical except those for the length. The pillars are identical in general except for their cross holes. Three of them do not have any cross holes, one of them has only one, shown in detail "b", and the four pillars used at the rear position each have two cross holes as shown in detail "a".

Next step is to cut the Crown Plate (1.3) and Beams (1.4) to length and trim using a file. The profiling is done with a 4 mm dia ball cutter running round the plate and the affected corners on the beams.

Cut the Bearing blocks (1.5) from stock material. It is advisable to make the cross drilling first. After that, fit all four parts together and finalise with the length of 7.5 mm.
