I am about to venture into a new project... built-in bookshelves for my family room. Question for the day is: Where can one buy predrilled sides for the shelves (used for ability to adjust shelf heights). I don't want cheap particle board. If you can't buy it, how would you recommend dealing with the issue, as I am concerned (if I were to use my own drill press) about the potential uneveness of the holes, which would cause the shelves to sit wrong. I also don't want to install the metal strips that are available if I can avoid it.

If anyone understands the above, and has some guidance, please let me know, and thank you in advance

 

I use this combination of hole drilling jig and self-centering bit.

It takes less time that it would to do it on a drill press. Especially so, if you don't have a large table for the drill press.

Hope this helps.
