Hi Toesy. Iroko is like no other wood I have ever used and every time I get a delivery it seems different. It can vary dramatically in colour, is quite close grained and as you ay, quite an oily wood, similar to teak in a way. The thing I find very annoying with iron is that some planks I get are what I call flakey, it is almost as though it is made up of layers but some of the layers are loose and not binding to each other very well.
It is a really nice wood for many of the things I make but whenver I make something I have to examine the piece of iroko I am using very carefully as one or two flakes, as I will call the, seem to be coming adrift. I get round this by sanding it back on my belt sander. this often cures the problem, the flakes though become even more highlighted when I apply a sealer or give it an oil finish. I feel more splinters will be had from this wood than any other so be wary of running your hand over it.
