NorthHeart:
When you use this method for a composite bow, and attempt to mate the horn belly to the wood core, is the idea that the 2 sides will literally fit together perfectly like a puzzle piece, male grove into female groove all the way down the limb?  If so, it would seem that any slight left to right deviation as your making these valleys would hinder a proper fit when you attempt to mate up the other side.

I have no idea, just thinking out loud.  A composite bow is something id like to attempt later on down the road.

if you choose this way you must control all the grooves parallel or the non match area will become empty and delaminated. Another method is glue the flat surfaces together and also perform well.

BowEd:
Using interlocking grooves actually assures durability and non breakage if done properly while tillering from the extreme reverse dried and cured profile.It will stop any cracks from migrating.Usually done on bows of higher poundage above 80 to 100 pounds or more but still good assurance on your first few 60 to 80 pound bows.Otherwise flat mating works well too on lower poundage bows.

loefflerchuck:
All the old grooved bows were non matching grooves. I have a Indo/Persian bow probably 200+ years old. It has the horn belly missing on one limb and you can see the construction. The grooves are far from matching. The idea here is many layers of thin glue sizing to have a thick glue line.

BowEd:
Correct.The interlocking grooved construction is a more modern type of construction used lately,but has been proven to work very well.
