Turned it. Then put a couple of coats of danish oil. Couple coats of wipe on poly then waxed it.

Here jockmike2 this is what i found on it:
Mora

Family: Leguminosae

Other Common Names: Nato, Nato rojo (Colombia), Mora de Guayana (Venezuela), Morabukea, Mora (Guyana), Mora, Moraboekea (Surinam), Pracuuba (Brazil).

Distribution: M. excelsa: Widely distributed in the Guianas and less so in the Orinoco Delta of Venezuela; dominant on river levees and flood plains forming dense stands. M. gonggrijpii Restricted to Guyana and Surinam, a dominant species best adapted to hillsides on heavy clay soils.

The Tree: Usually 100 to 120 ft high and 2 to 3 ft in diameter with clear boles 60 ft and more above very large buttresses that may extend 15 ft up the trunk. Trees of M. excelsa 160 to 200 ft high and 4 ft in diameter are reported.

The Wood:

General characteristics: Heartwood yellowish red brown, reddish brown or dark red with paler streaks; sapwood 2 to 6 in. wide, distinct, yellowish to pale brown. Texture moderately fine to rather coarse, rather harsh to the feel; luster medium to high; grain is straight to commonly interlocked, very variable; astringent taste and a slightly sour odor.

Weight: Basic specific gravity (ovendry weight/green volume) 0.76 to 0.84; air- dry density 59 to 65 pcf.

Mechanical Properties: (First set of data based on the 2-in. standard, the second the 2-cm standard.)

Moisture content Bending strength Modulus of elasticity Maximum crushing strength

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

Green (75) 12,630 2,330 6,400

12% 22,100 2,960 11,840

Green (42) 13,600 2,150 7,150

12% 24,400 2,790 12,700

Janka side hardness 1,450 lb for green material and 2,300 lb at 12% moisture content. Forest Products Laboratory toughness average for green and dry material is 228 in.-lb. (5/8-in. specimen).

Drying and Shrinkage: Drying reports are variable, generally rated moderately difficult to season; a slow rate of drying and careful stacking are suggested to keep warp and other degrade to a minimum. Boxed heart pieces tend to split. Kiln schedule T2-C2 is suggested for 4/4 stock and T2-C1 for 8/4. Shrinkage from green ovendry radial 6.9%; tangential 9.8%; volumetric 18.8%.

Working Properties: The wood is moderately difficult to work but yields smooth surfaces in sawing, planing, turning, or boring unless interlocked grain is present then there may be considerable “pick up” and chipped grain.

Durability: Results are variable; material from Surinam and Guyana is rated durable to very durable in resistance to brown-rot and white-rot fungi. Service life of 15 to 20 years in ground contact is reported. M. gonggrijpii is rated very resistant to dry-wood termites; M. excelsa considerably less so, not resistant to marine borers.

Preservation: Sapwood responds readily to preservative treatments; heartwood resist to impregnation, penetration is very shallow, and absorptions are low.

Uses: Industrial flooring, railroad crossties, shipbuilding, heavy construction, high quality charcoal wood.

Additional Reading: (34), (42), (46), (75)

M 150 282-3Logs are delivered to a sawmill in southern Nigeria. African mahogany

(mostly Khaya ivorensis) is in high demand on overseas markets. Export of logs fro

this region, as well as from most other tropical areas, is being restricted.

M 150 282-2Band mills in Ghana are designed to handle logs 5 feet and more in

diameter. Obeche or Wawa (Triplochiton scleroxylon) logs yield lumber favored for

joinery and millwork.

M 150 273-14In many areas of the tropics, fast-growing species are being introduced

future supplies of fuel wood and industrial wood. Batai (Albizia falcataria) is

a favored plantation species in the Philipines.

M 150 273-13 Shores spp. is still the major timber group harvested in Southeast

Asia. With modern chain saws, fellers no longer need scaffolding to get above larg

buttresses.

M 150 281 Felling of white lauan or almon (Shorea a;mon) with axes in the early

1900s in the Philippines. Most hardwood plywood now imported into the USA is

produced from species of Shorea.

[M 150 273-9Plywood mill in San Jose, Costa Rica, produces rotary-cut veneers mostly from banak (Virola spp.) and crabwood or cedro macho (Carapa guianensis). Logs trucked in from the Caribbean coast.]

M 150 273-21Mahot or Tauary (Couratari spp.) grows from Panama south to the Brazilian Amazon. Trunk diameters may exceed 4 feet above the stout buttresses. In tropical American moist forests, single species usually make up less than 5 percent of the stand volume.

M 150 273-18Trees in the tropics yield not only wood but a wide array of gums, oil

resins, tannins, edible fruits, medicinals, latex, fodder, and much more. The para

rubber tree (Hevea brasiliensis) at the end of its tapping life is used to produce

attractive wood suitable for furniture components.
