What is the wood

[Gerald]

Got this plank from a turners estate today and trying identify. I think it may be leopard wood. What is the consensus of opinion?

Following this.

Kinda has the look of lacewood also.  I am not familiar with leopard wood.  What does it look like with a bit of sanding?

[Larry Buskirk]

Looks like rough sawn QSO to me. 

[Gene Howe]

I won't venture a guess as to the species but, it's shore purdy! 

[Smallpatch]

Looks like the face of some american plywood.

Lacewood, like Cal said, is similar or maybe just another name?

 

[HandyDan]

Sycamore can have the same traits.

Sure looks like it . But I thought lacewood had finer grain.Looked up the specific gravity of the three and Leopard wood is heaviest by far. Guess I could weigh the piece and calculate weight per board foot.

ah, that's easy:  Smithwood.  if you slap it hard enough, it'll tell you all it's secrets.

leopard wood is reddish brown and will give you a sliver just for being in the same county. Lacewood is pinkish with light brown hues. it's difficult to tell what yours is in the rough form. give it a sanding  and post another pic would help

[Gerald]

Headed that way now and report back tonight

[Gerald]

I sanded some and did a dry pic and a mineral spirits wet

Common Name(s): Leopardwood

Scientific Name: Roupala montana (syn. R. brasiliense)

Distribution: Central and South America

Tree Size: 100-130 ft (30-40 m) tall, 2-3 ft (.6-1.0 m) trunk diameter

Average Dried Weight: 55 lbs/ft3 (885 kg/m3)

Specific Gravity (Basic, 12% MC): .73, .89

Janka Hardness: 2,150 lbf (9,560 N)

Modulus of Rupture: No data available

Elastic Modulus: 2,887,000 lbf/in2 (19.91 GPa)

Crushing Strength: 7,280 lbf/in2 (50.2 MPa)

Shrinkage: Radial: 3.5%, Tangential: 8.8%, Volumetric: 11.5%, T/R Ratio: 2.5

Color/Appearance: Has a very conspicuous flecking that gives this wood its namesake. The wood itself is a medium to dark reddish brown with grey or light brown rays, which resemble the spots of a leopard. Like other woods that exhibit the strongest figure in quartersawn pieces, (such as Sycamore), Leopardwood has the most pronounced figure and displays the largest flecks when perfectly quartersawn; this is due to the wood’s wide medullary rays, whose layout can be seen the clearest when looking at the endgrain.

Good job John

 

Gerald, how about a pic of the endgrain.

Looking at your sample, I don't think I've ever seen any leopard wood in person.

The grain is mesmerizing. What are the dimensions of the piece Gerald?

we use a few hundred board feet of it every year. it's a hard wood and gives you slivers just by looking at it.

Interesting.  What do you use it for, and what type of finish does it get?  Any pics for us?

Board is 6 x 70 aprox. Will look at end grain, but I think John has hit it

4/4, 6/4, 8/4??? Just curious. Would make some spectacular boxes, drawer fronts or perhaps even tool handles or??.
