Taken from the wood engineering handbook. "Commercial magnolia
consists of three species:
southern magnolia (Magnolia
grandiflora), sweetbay
(M. virginiana),
and cucumbertree
(M. acuminata). Other
names for southern
magnolia are evergreen
magnolia, big laurel, and bull bay. Sweetbay is sometimes
called swamp magnolia. The lumber produced by all three
species is simply called magnolia. The natural range of
sweetbay extends along the Atlantic and Gulf Coasts from
Long Island to Texas, and that of southern magnolia extends
from North Carolina to Texas. Cucumbertree grows
from the Appalachians to the Ozarks northward to Ohio.
Louisiana leads in the production of magnolia lumber.
Sapwood of southern magnolia is yellowish white, and
heartwood is light to dark brown with a tinge of yellow or
green. The wood, which has close, uniform texture and is generally straight grained, closely resembles yellow-poplar
(Liriodendron tulipifera). It is moderately heavy, moderately
low in shrinkage, moderately low in bending and compressive
strength, moderately hard and stiff, and moderately
high in shock resistance. Sweetbay is much like southern
magnolia. The wood of cucumbertree is similar to that of
yellow-poplar (L. tulipifera). Cucumbertree that grows in
the yellow-poplar range is not separated from that species
on the market.
Magnolia lumber is used principally in the manufacture of
furniture, boxes, pallets, venetian blinds, sashes, doors, veneer,
and millwork."
Dunno If that will help you. Seems it might be okay, not great though.
