Constructing the Seats: 20 & 21 December
|
Cut all the sections as set out
in the drawings, fit and hold with clecos to make sure
the seats at square and at the right angles. After
cleaning, deburring, etching and reassemble, start the
solid riveting process always checking to make sure the
seat remains square. TIP: When securing the top angle that stops the seat from coming out, place a scrap piece of 0.025" skin between the runner and the bottom aluminum rail before drilling and riveting the top retaining angle into position. This will ensure the seat slides without hindrance. |

I have read incident reports regarding aircraft with adjustable seats where for one reason or another, the seat has released allowing the seat to slide backwards during takeoff. As a result, the pilot has pulled back on the stick making the aircraft to stall. While I am not saying that this will happen to the BushCaddy, I have decided to put a stopper at the end of each rail and a stronger spring under the seat to bring greater pressure on the adjustment leaver.
The compression spring pushed over two 3/16" nuts and the angle bracket screwed to the bottom of the seat with the bottom of the spring making contact with the top of the lever arm making sure the pin remains in the rail hole |

T6 aluminum angle has been cut to size and fitted into position
using counter sunk solid rivets leaving a small gap between the seat in
the fully extended position and the stopper bracket. TIP: I would suggest fitting the stopper while constructing the seat so there is no gap between the rail and the stopper. |
