Gooseforsupper - I see in your pic, and read in your tutorial that you "line" the end grains up. So my question is how do you do this, I mean, what is it that you look for to line up. Obviously you can only line up one grain line on each piece other since they are separate pieces of wood with different grain patterns, right? I see your drawn on lines, but I'm not sure I understand what exactly you look for and try to line up. Can you explain a bit please?
Do you ever glue up more than one joint at a time, or always keep it to a single glue joint at a time? When I did mine I glued the 3 veneers up, and then stuck on the two caps on so I have 2 glue joints each time I glued.
Also, is your standard practice to drill prior, or after gluing?
I'm working on a Black & white ebony/ABW right now ill post up in a day or so. I love the look of the black and white ebony grain! 
Thanks!!!
I'll try and explain a little better so you can visualize it. I drill my pieces before I glue them together and then do one joint at a time. Other people glue then drill it all at once. There is no best way, just what you are comfortable with. I like to concentrate on each joint so I know it's right on the money and lined up perfectly. The way I line up the grain is to look at the end grain of the piece, you will see the growth rings in the wood. Notice which way the grown rings curve and get all the segments so they curve the same way. Then I take a straightedge and mark across the growth rings at 90 degrees right through the center of the blank. I mark on both sides where the lines ends up.
I use an undersized, waxed steel rod through the center hole to line up the two segments when gluing. That way I have the center dialed in and can line up the lines on the sides. That way I know the growth rings are all going the same direction.
Take note, grain also goes in a certain direction on the side of the blank in addition to just lining up the growth rings. I try and figure that part out and line them up when I am cutting and laying out the way the blank is going to go together, before drilling each piece. I hope that makes sense, but it will come to you as you play with more and more wood. I have some beautiful calls that I made where the grain is wrong and it still bugs me.
Black and white ebony is great stuff, can't wait to see what you come up with!
