Good Morning porch..    

Some long time ago, I asked the name of the curve 
which starts in one direction and then changes to 
the other - the curve of a shapely lady's calf (Sorry
Esther - a shapely man's calf too)

No one knew, but 

(Fanfare)

Thomas Corkhill, in his 'Glossary of Wood' knows.

Highly recommended book BTW, but like a 
dictionary, you need to know what you're looking
for before you can look anything up.  

and the answer is..
Cyma Recta - a curve of contrary flexure 
commonly used in mouldings. An ogee.

or

Cyma Reversa - the opposite of the cyma 
recta.  The upper part is convex and the lower 
part concave. See Cornice.

Cornice - (pictures here with more 
explanation and references.

THis is a fascinating book - includes the
common and botanical names of *most*
timber, amongst which it mentions the Rhodesian 
Teak I scored a couple of months ago..

Rhodesian Teak - (Baikioea plurijuga) Reddish brown
Also called Zambesi redwood, Mukusi, and Umgusi.
very hard, heavy, durable and stable.  Insect and fire 
resisting. It is not teak but has many of its qualities 
and used for similar purposes.  Excellent for block
flooring.  Difficult to work because of hardness.
SG .85, CW 4.5.  See teak

As always, can't help leafing onward, through the
descriptions of tools - here's what it says on routers
with illustrations of  a 71 and a coachmakers...

Routers ....
1. a woodwork tool for levelling the bottom of a 
trench or groove. See Old Womans's Tooth.  
2. Special tools for shaping and forming quirks 
on circular work etc. The various types are: beading, 
boxing, carver's, circular, coachmakewrs, fence,
 jigger, lining, ovolo, pistol, quirk, sash, stringing..
3. a machine for forming the joints of rounded 
corners for cabinet framing.
4. the Elephant machine, q.v. is called a heavy 
duty router

Excluding the species names  - though the 
descriptions of names, uses, and especially
 the alternate names of timber is *very* useful,
