Here's the finished article. I've used plastic brackets instead of steel so as to reduce the weight again, although a benefit of the latter is that you can knock it into place with a hammer. I'm probably the only guy out there building flying machines using a lump-hammer. An alternative that we might need to set these products straight is a heat gun, which we shall look at in due time should the need arise.
Notice that the perforations in the sides of the box make for altogether easier access, but nonetheless I do intend to retain solid sides going forward in order to recreate the telephone-box zeitgeist. Clearly carbon-fibre sheet is the outstanding material for this part of our air vehicle, because having to dispose of practically half of each aluminium sheet pierces my inbred sense of thrift.
Note too that the brackets are arranged with each face lying within the frame, so that the bolts that they will support do not lie outside the box and scrape the floor. The bottom-end of each con-rod will include a nut to screw into the bolt in each bracket.
The debate between studs and bolts has most often been seen in fitting car wheels. At the time I bought my first car whilst still at school, cars used nuts to attach wheels to hubs whereas now they invariably use studs and the hubs themselves are threaded. When did that sneak up on us?
