the REST of the pictures on this page will give you a better overall feel for this wood

wawabima / Sterculia rhinopetala

4" x 4" flat cut, 5" x 5" quartersawn, 1" x 1" end grain, and a 1/4" x 1/4" end grain closeup.

Diffuse porous with large, sparse, randomly spaced pores with some reticulate parenchyma, some confulent parenchyma, numerous pore multiples, fairly thick rays easily visible at 10X, vague growth ring boundaries.

This is a very coarse wood with strong blunting effect on cutting tools and is usually unattractive compared to many woods. I recommend against using it. The only reason I have so many samples is that I got a lot of them in mixed lots where they are thrown in readily because it's not a popular wood. The one plank I bought (my first sample below) ended up getting used entirely for shop jigs and firewood. As you can see from the bowl at the bottom of this page, this wood CAN be attractive in use, but it's a bear to turn because of silica content --- my own experience is more severe in this regard than most reports, so perhaps I have obtained pieces that were unusually fibrous and silicaceous.

a couple of small sticks that give excellent examples of the two main forms of side grain pattern characteristic of this wood.

plank listed as lotofa (an alternate common name) / Sterculia rhinopetala --- I'm pretty sure the color is just silly, even if the wood was moistened for the pic.

wawabima segment on a laminated bowl. On the left is how it looked fresh off the lathe and on the right is after one coat of natural stain to block moisture absorbtion until I get around to putting on a few coats of polyurethane. This is the bottom of the bowl, so you don't even see this unless you turn the bowl upside down, which is a shame because this piece of wawabima looks unusually nice.
