Cut laps, cork rails, hollow wooden

Me again…

When doing cut laps on cork rails would you extend the glass so it meets the wood on the other side of the rail or is that not necessary. What weight of glass would you use. 8’4" 23". Rail piccie attached.

Hicksy,

The more glass on the rails the better. I wrap the bottom layer up over the rails onto the ply deck by 1-2 inch and same from top to bottom. This avoids any grief with leaks at the join between the cork rail and ply deck. I’ve been using one layer of 6 oz glass top and bottom. I also have a layer of glass under the deck for extra impact resistance.

From the Swaylocks Glossary:

LAP a contraction of Overlap

A lap is an area of overlapping fiberglass_fabric, typically along the rails, nose and tail of a surfboard. When the overlapping cloth is roughly cut and left alone through the laminating process it is called a free_lap. When the overlapping cloth is trimmed or cut evenly during the laminating process so that it looks neater it is called a cut_lap. Laps may be sanded down or ground down before final glassing. A lap_line occurs where the lap is trimmed, or may be caused by a razor cut into the blank.

A free lap is a lap that has not been trimmed after lamination, rather the fabric is laminated down as it was originally scissor-cut.
