[Public-List] Steam bending Teak

[Don Campbell]

One consideration in this discussion is the species of wood used in the 
rails and constructin of the AL30. I have had suggested to me that it 
may be Afromosia or a Central or a South American species that is more 
closely related to mahogany than teak. The species, if teak, might also 
depend upon the country of origin with Burmese Teak differing from that 
grown in any other country. If you google teak  or mahogany substitutes 
you will get quite a range of discussions from afromosia  to Honduran 
mahogany to sapele and many more. These species all have different 
steaming characteristics!
