Many KRs have been built using Mahogany, and no issues with it. Steel is stronger than both.
See N64KR at http://KRBuilder.org - Then click on the pics See you at the 2009 - KR Gathering in Mt. Vernon, Ill There is a time for building and a time for FLYING and the time for Flying has begun. Daniel R. Heath - Lexington, SC I would agree with all of that except the mahogany ply. It does not have anything like the strength of Birch.
