I am in the planning stages of a project that will require 2 curved braces
approximately 3 feet long. The material is 5/4 red oak. I can cut the braces
out of an 8" wide board but the center line of the board will run through
the inside of the arc. I don't have a lot of experience at this but
something tells me that this will weaken the piece quite a bit. This is
mostly decorative so it won't bear a lot of weight; maybe 100 pounds at
most. I just don't want the brace to split. I would rather not use a wider
board... this stuff is already too expensive. Any advice would be very much
appreciated.

If the board is 3' long and 8" wide, and the center line of the board will
run through the inside of the arc, then you are cutting an arc considerably
less than a quarter circle, yes? I don't think you need to worry about
splitting across short grain, if the arc is that short.

It will be pretty close to a quarter circle.

What's the cross section dimension of the brace? 5/4 x 3' x ???. If it's
not too deep, use quarter sawn and steam bend it. With a roughly two foot
radius (3' is quarter circle), it shouldn't be a tough bend to do. This
would likely be the strongest solution.

what about a glue-up of narrow pieces, Michael?

That'll do, but for the lines from laminating. If they are
not a problem, it'd work fine. Thin oak will bend easily
when cold for the dimensions in questions. Just make sure
there's no significant grain runout. This would also be
better if the dimensions are big - 5/4 x 3' x , say, 3".
