Type II wood chips??

[Scott]

Was just reading the destructions for my newly arrived Veritas MkII Honing Guide and....


....could someone enlighten me as to what a "Type II wood chip" is :?: :shock:

....assuming of course that it doesn't refer to a roll of wallpaper! :?

It's the later model with the improved adjuster... :wink: Go here and go to the "Instr" link next to the "2-1/4" Blade, 38° Bevel" at the bottom of the page.

Cheers, Alf

Thanks Alf. Is that a common designation/classification for chips or a Veritas one?

 

[Alf]

I believe Mr Lee Snr. uses it in his "definitive" book on sharpening, so it's fairly widely known as well as being something of a Lee Valley thing.

R Bruce Hoadley uses the term in his book "Understanding Wood" (the first edition came out around 25 years ago).

D'oh! Now I recall that mentioned before; thanks, Frank. Amazingly I don't have either book. :roll:

Excuse me for butting in, and excuse my ignorance.

Are you saying that a, "Type II wood chip" is a 38 Deg blade?

Hi Gary,

Type II chips are produced by any sufficiently high angle blade be it in a BU or BD plane.

The higher angles simply cause the wood shaving to fold on itself ("break") at the tip of the blade before reaching a chip breaker (in the case of a BD plane).

This in turn limits the amount of tearout, which is caused by the shaving "climbing" the blade/chip breaker and splitting down and forward of the blade before "breaking."

Thanks, Mike.

Thats a lot clearer.
