I'm a bit confused about an article I've just read:
How then does the block plane behave any diferently than a bench plane, other than the smaller size?
Thanks,
Adam

Your answer is right there in the article just above the diagrams you mentioned.
"The block plane owes its handy size in part to the shallow angle between the blade--or iron--and the sole. "
Bob
So then the only difference is the size?
Can a low-angle block plane use a plane iron with a larger bevel angle to simulate a normal blade angle? Are there complications with the 12 degree clearance angle on the flat side that would make it behave differently from a standard block plane?
Jacobe,
Please reread my replies to your > Can a low-angle block plane use a plane iron with a larger bevel angle to
the bevel angle determining the cutting angle, but I somehow missed the bit about block planes being bevel-up.
There's still one point I'm not clear on, hopefully you haven't already adressed it :-) If I compare a regular block plane with a 45 degree total cutting angle and a low-angle block plane with a high-angle blade that also gives a total cutting angle of 45 degrees, there's one difference I can see. The low-angle plane will have a smaller clearance angle on the flat (under)side of the blade than will the regular plane. I would suppose that since this face of the blade isn't exerting a lot of force on the wood anywhere but at the very edge, this angle is relatively unimportant and the two planes described above would function similarly. Is that the case?
Thanks for your patience.
Adam
Yes,. 12 degrees is about the minimum for clearance angles. The wood can begin to fuzz behind the blade if you go any lower. Also, To maintain a Type ll cut, the blade needs to be sharpened within a specific range of angles. Just read about it tonight, but now it slips me. The minimum a steel blade can be successfully sharpened is about 25 degrees. The above was from Brian Burns booklet; Double Bevel Sharpening.

There's more to cutting than the edge. The gap through which the shaving must pass, the extent to which the shaving is curled, as well as the force behind the cut all play a role.
The major difference between a block and a bench plane has less to do with the angle of the cut than the way the shaving is handled and the way you handle (pun intended) the plane.
