the jig. Cut out section D from three separate pieces of 3/4"
thick particle board and joined with bondo. Cut as per plans.
Bondo'd to table, then cut part A and bondo'd to pieces E and D.
Cut the remaining jig pieces. |

Sanded LWA1's. Cut out CS6 & CS7 to fit (5-13/16 x
5-10/16). Cut BID for CS6 & CS7. Micro and 1 ply BID inside
spar. Installed CS6 & CS7 with micro, and added 1 ply BID over
both sides, lapping 1" on the outboard side and 5" on the inboard side.
Added 3 plies UNI over hardpoint sites. Installed LWA1s with flox,
1 ply BID and weighted down. Added reinforcements over CS5 & CS8:
1 ply BID, 3 plies UNI, LWA1s @ BL 65.5, 1 ply BID, and weighted down.
Added center section bulkhead with 1 ply BID on both sides. While
this was all curing I cut out the BID for CS4, micro'd and epoxied.
Added peel ply, 1" around all edges, and left to cure. |

Forward face |

5.98 |
2 |
Trimmed CS4's and box, made sure there's a good fit for
the forward face. At this point I cut a 1-1/2" hole through CS6 &
CS7 and installed a plastic grommet ($2.99 ea) with 5ME. This will
be used as a conduit for cables and wires coming from the wings.
(Later I'll make similar cuts in CS5 & CS8.) Installed CS4 on the
spar with micro, and weighted and taped down for cure. |

Spar cap layup |
12/24/07 |
|
4.5 |
Bottom spar cap layups. I've been lapping the tape over the edge
by about 1/2". Over all these plies, this adds up. It turns
out that I was short spar cap tape on this roll by so much that there
was no tape left for the last four plies. Fortunately I had some
left over from the canard spar cap, and I was able to add two more plies
(the 4th from last and the last). The plans specifically state
that you can leave off two plies for the appropriate thickness, so I'm
not going to worry about it. Now I wonder if I was shorted some
tape!! |
