and T. africana

Makore

Douka

Family: Sapotaceae

Other Common Names: (T. heckelii) Baku (Ghana), Makore (Ivory Coast); (T. africana) Douka, Ukola (Gabon).

Distribution: Both species together are found from Sierra Leone to Cameroon, Gabon, and south to Cabinda; widely distributed in the high rain forests.

The Tree: Reaches a height of 180 to 200 ft; boles straight, cylindrical, and clear to 100 ft, free of buttresses; trunk diameters generally about 4 ft but may be up to 10 ft.

The Wood:

General Characteristics: Heartwood pink to pink- or red brown; sapwood 2 to 3 in. wide, whitish or light pink, clearly demarcated. Texture fine to medium; grain generally straight; lustrous; sometimes with an attractive moire figure. Liable to stain in contact with iron when damp.

Weight: Basic specific gravity (ovendry weight/green volume) about 0.55; air-dry density 42 pcf.

Mechanical Properties: (2-cm standard)

Moisture content Bending strength Modulus of elasticity Maximum crushing strength

(%) (Psi) (1,000 psi) (Psi)

Green (16) 10,900 1,190 5,300

12% 14,700 1,470 7,730

12% (47) 17,400 1,630 9,700

12% (47) 16,000 1,460 8,100

Janka side hardness 930 lb for green material and 1,110 lb for dry. Amsler toughness 126 in.-lb at 12% moisture content (2-cm specimen).

Drying and Shrinkage: Dries at a slow to moderate rate with little degrade. Kiln schedule T10-D4S is suggested for 4/4 stock and T8-D3S for 8/4 (T. heckelii). Shrinkage green to ovendry; radial 4.7 to 6.2%; tangential 6.8 to 8.0%; volumetric 10.6 to 11.0%. Movement in service is rated as small.

Working Properties: A high silica content causes blunting of cutting edges, particularly in dry wood; works reasonably well with hand and machine tools, good veneering properties, finishes well, good gluing properties. Fine dust may irritate nose and throat or cause dermatitis.

Durability: Heartwood is highly durable and resistant to termite attack; sapwood liable to powder-post beetle attack.

Preservation: Heartwood is extremely resistant to preservative treatments; sapwood moderately resistant.

Uses: Furniture, cabinetwork, joinery, decorative veneers, paneling, boatbuilding, flooring, turnery, marine plywood.

Makore is also known as "African Cherry"

Thanks and an apology

Steve Kubien

>First of all I want to apologize for not putting my name on my original post. As you all know, I usually do but I typed my email address into the "name" section by mistake.

Thanks for the info on makore. I'll have to check but I recall Krenov mentioning douka in one of his books as one of his favourite woods to work with. I'll have to confirm that. Don't quote me. I got a couple of small slabs (2x12x36" rough) for $15.00 each and want to use it to make a pinning kit for locksmithing. I'll try to post pics whenever it gets done.

Again, thanks,

Steve Kubien

May want to contact Mike Schwing

>If I remember correctly that end table he made was curly makore and he had a seriously bad reaction to the dust.I also seem to remember that when searching for info on this wood it was somehow related to the poison ivy family.I could be wrong but better safe than sorry.Mike is a regular on the turning forum if you can`t catch him here.

>Steve,

Search the archives... Mike posted his Curly Makore Shaker table on the hand tools forum. Just beautiful!

Brad

PS - Nice pickup on the Makore did you get it at Century Mill??

How did you know?

Steve Kubien

>Yup, Century Mill was the source. They a GREAT piece of 3" thick purpleheart to make the box out of. I was tempted but that would've meant ordering a high-angle smoother from Steve Knight. Dont' get me wrong, I like Steve and love my 45 degree smoother but a new plane is not in the budget....

>BTW... are you going to the Tools of the Trade in Pickering this weekend?

I was over at a friend's storage locker last night checking out what he was taking to sell. Sounds like it will be a great show!

Konrad (Sauer and Steiner), the Sheppard boys, Vlad (Spehar ToolWorks), and Andre Mirouette (sp?) will all be there. This is in addition to the usual assortment of guys selling handtools.

I think I will be going if so it would be nice to meet!

Brad

PS - Good steal on the Makore!!!
