if you're an AAW member, there's an article in Feb 2013 journal (I think that the right month) about wood bleaching.
most of the commercial bleaching kits are no longer sold, but you can acquire components very easy:
100% pure lye (sodium hydroxide) available at any hardware store as "drain cleaner" (about $6)
water
27% hydrogen peroxide - available at some pool supply stores under brand name "Bacquacil" - you'll need "Step 2" (about $18/gallon)
I believe the steps go like this:
measure out 1 cup water into a glass container with a non-metallic lid. Add 1 TBSP lye. Close lid - shake well. Lye must be completely dissolved. Label jar "Caustic" - store it away from children.
Put on personal protective equipment - rubber gloves, old clothing with long sleeves, face shield, etc.
pour out just enough lye mix into a bowl, and brush onto the wood you want bleached
pour out a small of hydrogen peroxide in a bowl. brush it onto the wood immediately after the lye mix.
it will foam up. let dry, repeat several times until desired effect is reached.
lye on the dried bleached wood should then neutralized with white vinegar.
I have done this recently on a piece of holly. left side was bleached, right half is natural. Note that the bleaching is limited to the wood surface (maybe 1/32" penetration) - so you need to have turned to near your final shape, and done most sanding before you start bleaching
