The late Bruce Viney was a genius in building wooden puzzle boxes, many similar to the Japanese puzzle boxes, and sold plans for them at very reasonable prices. His son now owns the plans and is making them available again.
For now, PDF catalogs of the free and paid plans are being made available for download from this site. Inquiries should be directed to email@example.com where arrangements for payment and fulfillment of the purchase are done.
Below are just a small number of pictures of the puzzles he created.
