As I mentioned in another entry, the seat requires hard points where bolts and rivets go through it (or are attached). These pictures show more of these locations for the hard points.
Picture #1 is of the back of the seat. The upper right of the picture is actually the bottom edge of the seat, while the lower left of the picture is the top back of the seat. Every place that a hard point will be located at is drilled through on side of the fiberglass and all the way through the foam but NOT through the other side of the fiberglass. In most of these cases, that means that I started drilling through the back of the seat but stopped before I drilled through the front. The drilling is typically done with a 1" hole saw...slowly and carefully. Once the hole has been drilled, the foam is removed leaving a hallow. Later this hallow is filled with a mixure of thick mixture of resin and microballons, and a patch of fiberglass cloth is added thus sealing it and creating a hard point of a hardened resin with filler (microballons in this case) between two skins of fiberglass.
Picture #2 is the bottom of the seat. The bottom of the picture is the most forward portion of the seat. The two hard points there are for seat support bars. Near the top center of the picture is two small holes that have been marked as being in the "Seat Attach Angle" area. These are the bottom areas where the seat will be mounted on the seat attach angle that was shown being installed in earlier entries.
Picture #3 is the opposite side of what picture #2 shows: the top of the seating area of the seat.
