You can bleach wood with oxalic acid pretty well, but to make the color 
even, you need to do the whole thing. Bleaching usually does a good job. If 
you don't want to refinish the whole thing you can sand the dark spots out 
and touch up. A little stain to match the rest of the tiller might work, 
but I'd do the whole tiller myself; it isn't that big a job.

My tiller is delaminating, too. I'll either reglue & refinish it this 
winter or build a new one, which might be a nice project.

Mine is a nice double curved tiller which might be ash (?) on the outside 
with a mahogany (?) core.  Does anyone know is there is an Alberg 
"standard" tiller shape, or can I be fancy free in designing a new 
one?  I'd probably make a new one shorter since I don't need all that 
mechanical advantage, and bent up higher so the autotiller is more 
level.   I've noticed a few replacement tillers for sale at Fawcetts which 
might fit, but  I can make a better one myself.  Any ideas as to what a 
good laminate be made from?  Ash, oak, mahogany, etc?

Also,  has anyone built a new set of spreaders? Might be another 
woodworking project fore the Winter. I guess it would be pretty 
straightforward. I'll drop my mast this season and see how good/bad the 
spreaders are. May not even need anything. Every coupe of years I spread 
some glop across the spreader tops and no problems yet (knock wood).
