Well, I had great fun demonstrating this at the show, which had moved into the shop.
The ultra close set chipbreaker even did a decent job on the wood from hell, Indian Laurel, (thank you Rob).
I am particularly pleased to have learned this "new" old technique. Not sure how it had evaded me for the last 40 years.
I'm afraid I can't help with the hair Ali, just a combination of genes and the attitudes and fashion of the late 60's........
Best wishes,
David
