I'd question the sharpness of the new knives.

Alex,

Use a sponge and some mineral free water. Lightly dampen the wood with the
sponge a minute or two before planing. Dampen for each pass taking light
cuts until you're down to your final size. I've used this method plenty of
times and it works 99% of the time but you must take light cuts. I also use
a drum sander to slowly plane down stock subject to tearout and that takes
many passes but does a nice job.

Yep, don't want the interaction between what's in the wood and what might be
in the water.

Mix your water-based dyes with demineralized or distilled water, too.

Buy a new clean spray bottle and put clean water in it so you won't stain
the wood. As the maple is fed into the planer, mist the surface of the
board. This normally will eliminate the tiny tear out on soft maple .

I use water based (aniline) stain on soft maple with good luck. You should
raise the knap on the wood with the spray bottle and scrape the surface to
smooth it before you stain the wood. Some follow up with a wash coat of
shellac and a wipe on stain after the aniline stain.

Straight grain doesn't tear much, curly figure can be a bear since you can't
pick a constant downhill (down grain) direction. Best I've found is to feed
with particular attention to downhill, sometimes reversing from side to
side, and then slicking the whole with a scraper or plane.

Hard maple is a worse offender in the chipout department because the rays
are a built-in fault line. On the quarter figure, you can get a lot of
peck-out. Perhaps you have hard maple, which is much more common out east?
Soft maple isn't consistent enough in color to be used much in furniture
when there's an alternative available. Flooring and pallets, interior of
upholstered furniture are the main uses for soft around here.

In my experience, yes.

Not necessarily. It can be absolutely beautiful, when done.

You might want to consider using handplanes or a sander, rather than taking
the planer as your finish pass. A really sharp plane, with a tightly
closed mouth, should be able to get your work acceptibly flat, and tearout
free.

Or a scraper, in one of its forms, will do the trick.

I've built a lot of stuff from soft maple, including kitchen and bath
cabinets, bedroom furniture, and a few clock cases. It works well, when
care is taken.

There are a bunch of 'soft maples', at least a dozen, sold commercially.
In the Pacific Northwest, Big Leaf maple is one of them, and is a beautiful
furniture wood.

We regularly get at least three noticable varieties in the racks at my
Oakland, CA wood merchant, as 'soft maple'.
