[modeleng] Re: Alternatives for sleepers Jarrah now OT

Jabrock is a hard wood grown in the Philippines.
Not too common now as so much of all woods there have been depleted.

Lignum is, I believe, from a south American tree.


As for wood for roads, I once came across the amount of wear on wooden roads 
in London, and added it to my website as the sort of trivia that might 
interest someone.

I have been interested in the discussions about Jarrah because my father,
(who was an aircraft fitter in the 1940s) occaisionaly brought home blocks 
of a
material which he called Jabrock.
This material was made up of wooden laminations each about 1/16 inch thick
and appeared to be available in thicknesses up to about 3 inches. It was 
very
hard and surprisingly heavy for a product used in aircraft. Could this have 
been
made from Jarrah?.
Another thing which has always intriged me is - what does a lignum vitea 
tree
look like?.
