I made a drill press table with removable insert and a high/low fence from Yeung Chan's book. Lessons learned:

(1) I can't adjust the table height because I didn't consider making room for the adjustment handle to turn (see 3rd pic) - next time I will remember to go through the motions of using the drill press in order to visualize any issues;

(2) the removable insert is not centered with the drill point because I incorrectly assumed that point would be centered with the table frame (it's not);

(3) if you try to make a stop cut on the table saw, the other side will have a curved dado in it...

Payoff: Now I can clamp wide pieces to the fence and drill accurate holes. Also, I can clamp stop blocks to the fence to make repeatable holes.

Hope this helps someone!
