While making an 11″ diameter by 5/8 thick disc I have a problem with the end grain of the Bloodwood becoming black. In the attached pic you can see that the wood has a darker color on one side of the radiused edge depending on which way the cutter was cutting. (with or against the grain)
The wood is bright when sawn with a band saw but turns black when sanding
What’s going on ( and how to prevent it)?
thanks
Chris

Chris , there is nothing wrong , it is just the grain changing direction. You can work your way through the grits with sand paper working your way up to 400 grit in effect polishing the edge, It will look fine after finish is applied.

Sanding also turns the edge black
Perhaps I 'm not explaining it clearly. The photo shows two areas one routed witrh the grain and one against. Routing against the grain produces a rougher and brighter finish. With the grain the smoother finish is much darker.
The sanded area also turns dark instead of bright as you would expect. Hand sanding is worse than random orbit sander.
It's straing to me, it seams as if the end pores are filling up or bending over
