The crotch strap kit (ordered separately from Van's) adds anchor
points under the forward seat floors for attaching 5-point harness
crotch straps.
Curiously, the openings and pilot holes in the forward seat floors
were already cut out in the QB kit, even though the crotch strap kit
is not included. I verified the measurements of the openings and
pilot holes, then started drilling the anchors to the floor ribs. After
painstakingly positioning the anchors, measuring, and re-measuring,
and test fitting with the seat floors, I clamped them in place and
went to work using the angle drill attachment. Finished three of
the four anchor plates. |

(0.5) Finished drilling the fourth
anchor plate to the seat ribs.
 |
| 2006.03.08:
(1.0) Match-drilled the bolt holes
through the plates. Installed the fwd seat floors and
match-drilled the screw holes into the crotch strap anchor
plates. Removed the seat floors and the anchor plates from the
fuselage. |
| 2006.03.09:
(1.0) Drilled and countersunk the
anchor plates for nut plates. |
| 2006.03.10:
(1.0) Started deburring the anchor
plates. This is a lot of work, having a lot of "edge"
and a lot of edge features with all the flanges, etc. As noted
in the instructions, the rectangular cutout has to be edge-finished
especially well so that it doesn't damage the crotch strap fabric. |
| 2006.03.11:
(1.0) Finished deburring the
edges. Also used a 3M disc to buff out some surface scratches
caused by the shims I jammed between the anchor plates to ensure
correct spacing. |
| 2006.03.21:
(1.0) Applied corrosion protection
(AKZO) to the anchor plates. |
| 2006.03.26:
(1.0) Installed the anchor plates in
the fuselage.
