When and how to install the side rails?Updated 2 years ago

Here is a useful way to do the side rails 

1. Mill two sets of 1/4” side rails 1” wider than the widest point in the board.  This will be between around 4-6" depending on the board model.
2. Attach inner rails to the board with glue and drywall screws (temporary clamps).  
3. Remove the drywall screws after the glue dries.
4. Install the outer rails with glue, clamping in place with spring clamps as required to ensure solid contact with the first rail. This was every 6-8”.  See photo.

Alternatively, you can use straps, longer clamps, or even tightened saran wrap across the width of the board. Just do one layer and one side at a time.  I also recommend using screws at the nose and tail if you will be cutting those sections off for the nose and tail blocks.  See the photo below.
