Tatajuba Wood Slabs

Tatjuba is a wide, tall tree with very few branches in the lower sections which makes it a perfect candidate for a clear grade slab. Tatajuba has seen little movement on the market as lumber as of yet but is starting to get noticed because of its beauty and durability. The sapwood is thin and remains a yellowish white. The heartwood grain is usually very straight and can exhibit some of the “ribboning” pattern much like that of Sapele or Sipo. The light tawny brown heartwood is very uniform which shows off the figure from autumnal to spring growth very well. Since the tree is so straight with few low branches these slabs can get rather large. The straight grain makes surfacing and sanding a pleasure but some tear out can occur in the more figured spots. If this occurs slowing down the feed rate should solve the problem. Cross cutting and ripping is done without much cause for concern but some grain tension can stress saw blades and a riving knife is always recommended. It takes a finish well and can be sanded to a fine finish. We expect in the near future that this wood will see an increase in use as a decking and siding. Furniture builders will appreciate how the wood can be manipulated and anyone looking for a wood that is good consistency in color will love it as a slab. Our biggest and straightest logs are chosen to be sent out as a slab because it shows the beauty of the entire tree. Some of the best reasons to cut the highest quality logs into slabs are because: • Slabs have the highest yield of any form and using the most wood out of a tree is imperative to sustainable harvest which we are committed to • A slab that comes from a lesser quality log will be prone to be less stable • Voids in some logs means that they would not be suitable for slabs We believe that offering some of our Tatajuba in the highest possible yield is imperative to keep our wholesalers competitive in an ever changing wood world. Our experience with Tatajuba means you can always be assured that we will supply you the very best slabs. Just imagine being able to sell a new and exciting wood in a new and exciting form. This can be the thing that gives you an edge over your competitors and something very few mills can offer with integrity and quality.
