Title: A question on quarter sawing boards.
Post by: KShip85 on January 26, 2013, 08:40:47 pm

I thought I understood what grain was important when it comes to quarter sawing.  I had always assumed that the grain on the back and the edge were important.  After ordering a backing strip from a bow making supplier I question how important the edge is.  The back has fairly straight grain but the edge seems like not much attention was given.  Can anyone clear this up for me?

Maybe this pic helps, or I'm missing something. For backing strips they should be quarter sawn as well, much stronger and less likely to lift.

The grain in red is what I was curious about, maybe its not as important.  Also how smooth does the glue side of the strip need to be before gluing down?  The piece I have still has some saw marks showing.  Thanks again everyone.

I wouldnt sand down the glue side very much cuz if you sand it down super smooth then the glue doent have anything the hold on to.  100  grit should be fine.

I use 36 grit on my belt sander, get the saw marks out and that will work for tight bond, bub

You can also make a scraper from two pieces of wood and a fine tooth hack saw blade to prep the mating surfaces. Brush off all the loose stuff before glue up.

Better if the grain is straight no doubt. The bottom photo looks kind of wierd because if its quarter sawn there should not be any deviation. ???
