Hi!

Maybe you already know my scraping videos, maybe you don't.
In any case, you might be interested it my latest one:
Dovetail scrapingYouTube - ‪Scraping in a dovetail - detailed‬‎ (link also posted at HSM)

Hope that doesn't qualify for a shameless plug. :crazy:

If you have any comments or questions, feel free to ask!

Another excellent presentation Nick :cheers:

The only thing I can teach you is that it's "a master" not "an master". Doesn't depend on the gender of the object it's normally "a", but "an" is used when the following word starts with a vowel (aeiou).

Been playing with scraping hard steel with the Biax tonight. It looks like a positive relief angle is best, but wears out very quickly.

Ah, thanks for that. Forgot the rule!

Can't give you too many tips on that.
I had better results with a very acute angle between work and blade. And very little pressure! You could try it with a hand scraper, so you have a better feeling for the applied force. Also a low cutting speed seems to improve the quality. It's almost like just delicately wiping over the work, but still you remove enough material.
I didn't have much luck with a positive rake. Looks more like a neutral one is the right direction.
Maybe oil helps? I didn't try.

Many thanks,

I saw most of them.

Do you have one related to the finishing polishing ?

Polishing?
Clean, oil, assemble, and let run. Wipe off the dirty oil and re-oil.
