@ Rod :
Yes, it would be nice of you to send me a scan of all these relevant pages of Salaman's book.
Let me known also an address where I can ship the "pass around" sample so you, Douglas, Jim, Steve (perfect french speaking btw), Andy, (others ?) can do the test. Unless you disagree, I will produce for this test a quite "common use" rasps, let say a Cabinet Markers 8", stitching grain n°11 ?
@ Andrea
Hello Signora,
Yes, I have produced one special series for Alessandro Tossani from Cremona Tools without sand-blasting. He was thinking that this last cleaning operation could slightly reduce the bite of the teeth, and actually he was right. The bite is even better without that operation, but as you said, the rasp looks ugly, and this cannot satisfies me. So since then I am investigating to improve further my rasps by having a cleaning operation who gives perfect result withouth changing anything to the bite of the raps.
I have found a technical solution that allowed me to make 80% of the way. Once the 20% remaining will be covered, I will come to Alessandro to offer him the solution.The rasp sent to Australia that you mentionned has been cleaned with the new technique, as all are now.
As regards our very specific "secret de fabrication", I have detailled in this answer to the Australian forum what can be revealed (
