Brian:
Sapele is an excellent project wood. Here, in Annapolis, it is readily available in 8" – 13" widths, 6/4: it is my preferred wood for rocking chairs – the ribbon grain can be quiet attractive when designed-in.
My next commission is a contemporary desk and side-table – in Walnut and Hard Maple – this should be interesting… Sapele might be too dramatic for a full-width desktop (~60″ × 27″).
