Sipo wood

Sipo Mahogany (commonly referred to as either just Sipo or Utile) is an African wood that is considered to be the closest, aesthetically, to Genuine Mahogany (although not a true Swietenia). Its interlocked grains are akin to other African woods and generally produce a characteristic contrasting light-dark / two-toned sort of appearance, when quartersawn — which can be visually stunning in the case of more chatoyant boards. The fact that the wood is considerably easier to work, with less tearout, than African Mahogany and possesses a hardness that places Sipo between it (African Mahogany) and Genuine Mahogany has seen it transcend from relative obscurity to become a quite popular and highly regarded mahogany substitute wood, presently.

Aesthetically, the wood is similar, also, to its African first cousin, Sapele (with both being species of the Entandrophragma genus) — although Sipo is more pourous, and has richer color.

The heartwood matures from a pink-brown when fresh cut to deep red-brown. The grain is interlocked to rather irregular, producing a wide irregular striped figure on quartered surfaces. The wood has a faint cedar-like smell. It is extremely resistant to preservative treatment and resistant to decay.

 

The wood saws and works fairly easily with both hand and machine tools, with only slight blunting effects on cutting edges. In planing and moulding operations, a 1520° cutting angle is recommended to avoid picking up of grain. Finishing usually gives good results, with a nice polish, but the use of a filler may be needed. The wood is not liable to splitting in nailing and screwing, with good holding properties. The gluing, staining and polishing properties are satisfactory, but the steam bending properties are poor. A tendency of charring is present in drilling operations. The wood is suitable for veneer production.
