Abstract
A method of making a hardcore honeycomb panel comprising the steps of providing a multilevel stack of planar boards of grained lumber fastened together and arranged in the stack in step-wise fashion with alternate levels comprising spaced apart board strips forming longitudinal channels in the stack sandwiched between boards having the width of the stack, cutting the stepped stack on a first cut line through the side faces thereof at a predetermined acute angle, such as 12.degree.-30.degree., between the cut line and the bottom face of the stack and making subsequent coplanar cuts in this stack at predetermined distances from each other for providing a plurality of cut segments whose top, front, bottom and rear faces are rectangular and whose side faces are rhomboidal and which have angular channels therethrough. These cut segments are then sub-divided into a plurality of coplanar pieces which are fastened together to form the honeycomb panel having angular channels therethrough with alternate pieces being inverted 180.degree. about a longitudinal axis through the center of the piece so that each of the piece adjacent end faces for every other one of these pieces of batten-like mem…
