Hi,
I have two No 4 smoothers myself, one with a 10 degree back bevel on the blade. You can tame most any tear out with that combo and a planed table top is definitely achieveable and in my mind desirable. I don't doubt the LV smoother is a fine tool and coveted one myself, but a 58 degree blade to make a low angle into a high angle always seemed a bit nuts to me- got to be hard to push that wedge. An EP of 55 degrees is easily done in Bailey planes and needs a blade with an included angle of ony 35 deg, so not too tiring to use and readily availible.
Enjoy :ho2

So, if one has a spare no4, is a 10 deg back bevel something you recommend? I have some birch that don't respond well to a sharp no4 as it is now.
Hi,
It is easy to remove the back bevel if you don't like it, so give it a try. Hone a 25 deg primary as usual and just ligtly hone an edge at about 5 or 10 deg on the back. Only about 1/2 to 1 mm is needed otherwise the cap iron will not fit correctly, and you will find it difficult to adjust the plane. It doesnt take long to re hone after that, just alternate from one side then the other each time it needs doing, so maintaining a very short back bevel. Interchangeble irons are a good way to go, if you dont have 2 smoothers.
Regarding being a scraping action, it technically isn't as you would have to go to a much higher EP for that. Many infills of old were available with higher pitches, York pitch (50 deg) was a favorite and they were still planes all the same. We are just trying to emulate the same here. if it gets you out of a difficult spot, then don't question the technical reasons, just enjoy the fact that it works.
Mike.
