Here are a couple of rough sketches to show how I have been making crests for helmets for many years now, this is where one can make a thinner wood frame by only drilling one row of holes down the centre of the crest but only taking the holes down 10 to 15 mm depth.
The width of this type of crest box only needs be 20 to 25 mm so that the stagger of the holes make for a closer position and more tighter hair in the crest.
The other two sets of hair tufts are held in grooves cut in the side of the wood block, these grooves are marked out accurate as shown from the base line of the curve. This is where after drilling the centre row of holes one cuts the grooves with a junior hacksaw in a V shape as shown. Then these are filed out to curves with a rat tail file taking the depth below the 180 degree depth so that when the two rows of side tufts are glued in they are clear to allow thin ply to be applied to the sides of the block that creates the finished crest box.
