Maybe I'll do that - cut into two, cut out the cracked sections,
resurface the faces in my planer, and then glue them back together. A
somewhat smaller bowl, but probably safer to turn?
A while back I was taking a woodturning class, and while scraping the
outside of a bowl it literally exploded - I never did find all the
pieces. I think maybe I would like to avoid that again if possible.

Here is my 2¢ worth.

Every type of wood appears to behave differently.

In many cases, filling a hairline cracks with the appropriate glue gives
satisfactory results. Each case has to be handled individually.

I at one time was turning cherry wood and part of it flew off. Luckily, I
was wearing safety goggles. In hindsight, I should have been wearing a
complete face shield.

Since then when I turn cherry and oak blanks, I hunt for hairline cracks
first. If I find a hairline crack, I use the blank for something else.

Several times, after finding hairline cracks in cherry, I have split the
blank in two halves and glued them together.

Then after turning the glued blanks, the results were not too satisfactory.
I hate to discard cherry blanks with hairline crack but safety comes first.

There is no one answer in a case like this. Personally I would likely cut
along the crack line and use the wood for something else. I have tried the
other route and have never been happy with the results. I would rather
work with a wide crack as a design feature than a hairline, but that is
just me. This is personal business.
If you go the route of using thin CA to stabilize the crack and then turn,
continue to use the glue as you turn the bowl. It may have wicked all the
way in first time but then agian it may not. Remember that it will show
up in a wood like maple and that many finishes will make it even more
obvious.
Which ever way you do it, the turning will be fun. Nothing to lose so go
for it.

I have a maple bowl blank that is 8x8x4 in size. The probelm is there is
a hairline crack that has appeared on the end grain. It runs from the top
surface to the bottom near the center of the piece. On the top and bottom
surfaces, the crack extends about 2 inches in on one side and one inch on
the other. If the crack was to further extend through the piece, I would
roughly end up with two 4x4x8 blanks.
Should I (1) proceed with the bowl turning anyway or (2) Cut it into the
4x4x8 pieces and do something else with it? If I go the bowl route, what
precautions should I take? Thanks
