Cutting Board Counter

Sanding an End Grain Cutting board/butcher block.?

I am attempting to sand down an end grain cutting board/butcher block counter top. I need to take it down about 1/8 of an inch to level it and take out all of the imperfections. I have tried a palm sander, hand planner, and a large porter cable random orbit sander with as low as 60 grit sand paper. None of these have made the slightest dent in the hard maple end grain. Any suggestions?

A router would work if you had the proper skills and wanted to invest in building the proper jig to flatten the surface.
Go get yourself the biggest, meanest,Porter cable belt sander you can buy or rent.Get a pack or two of 36 grit sanding belts(basically gravel glued to a belt)& prepare to sand.
Secure the top so it WON'T move.Sand diagonally one way first and then the opposite.When your close to flat & your imperfections have gone bye-bye,start sanding longways to get rid of the cross-grain scratches.Then you can use your palm sander or random orbit to bring up the finish you want.I'd go to 220 grit on that end-grain.
I'm not sure how big your top is but,it should not be too difficult of a task,just kinda dusty.
