Pear makes really nice blocks. Hard but workable at small scales, and a nice natural color that is easily enhanced.
A good quality miniature drill press, adjustable x-y table, machinist's vice as well as a good miniature table saw with the best blade for ripping and slotting, and a good set of durable small drill bits will be essential. Micro-Mark has some of each in their catalog, but I am sure that the Talented craftsmen here can advise you better than I on this and other tips regarding your block making. there are also good instructions, methods and techniques available as to how to go about efficiently making your blocks. I am sure you can succeed given enough thought, planning and research into the project. There must be members on this forum with the experience, and almost surely a U-Tube video on the subject. In fact a good resource with clear instructions as to how to go about making your own blocks is
"Waterline Dioramas A Modelbuilder's Artform" by Justin F. Camarata, SeaWatch books, This book is a fascinating treasure trove of inspiring pictures, techniques and methods, including making believable sails. A valuable addition to any model shipwright's library.
