carefully drawn cardboard (bristol board) templates drawn
from autocad dimensions to get the curved shapes accurate
the cardboard templates can be traced around,
making it easy to draw the same accurate shapes 16 times on plywood
beams are almost 16 feet long,
plywood is 8 feet long,
so two 8 foot templates attached end to end to make a beam,
Lock specifies a 12:1 scarf, so the 1/2" plywood will need a 6" overlap,
this is allowed for in the templates
templates placed on plywood and adjusted to minimize plywood waste
