The subject basic method and its modifications are used to provide logs reconstituted from smaller diameter trees up to 12 inches diameter at their bases. The basic method is practiced using the following steps:1. Cutting felled trees at cutting points into a plurality of segments which, naturally, are tapered, each segment having a length, a larger diameter end and a smaller diameter end, the length being in a range of random lengths such that the larger end diameter is in a range of 0.2 to 2.0 inches larger than the smaller end diameter, with 0.2 inch preferred;2. selecting from the plurality of segments cut from one or more trees, a plurality of groups of segments which have smaller end diameters no more than ½ inch different;3. joining segments from each group end-to-end to form reconstituted logs of optimum lengths for processing into wooden structural units.In one modification of the basic method, flawed portions are removed from the logs prior to cutting them into segments. In a second modification the individual segments are processed into wooden structural units which can be joined end-to-end to provide longer units. A third modification incorporates both the removal of flawed portions and the processing of the segments as stated for the second modification.The subject method reduces wastage by as much as 80%.
