The Sagulator helps you design shelves by calculating shelf sag (deflection) given type of shelf material, shelf load, load distribution, dimensions, and method of attachment. You can also specify an edging strip to further stiffen the shelf. See the notes below for usage tips. Notes 1. The deflection calculations use average wood stiffness properties of clear, straight-grained samples measured in controlled laboratory conditions (mainly from the U.S.

I blogged a couple of weeks ago about what I should charge for a small box I was asked to make. I thought that those of you who haven’t delved into the wonderful world of box making might like to journey along with me as I make this commissioned box. I was given the outside dimension for the box, as the owner intends to place it in a chest of drawers, so it must fit the size constraints of the drawer. The box will be 95mm high x 360mm wide x 240mm deep (approximately 3.75” x 14” x 9.5”).

Use a 1/2” 14 degree dovetail bit in a table mounted router. Bolt the 3/8” spacer fence over the table with a 1/2” space between the fence and the bit. This space is measured from the bottom of the dovetail profile, not the tip. Set the height of the bit at approximately 5/16 so the slot will fit over the spacer fence. It will be necessary to drill another hole for the dovetail bit operation (predrilled in the Router Workshop Table Top). Remove the bolt in the end of the spacer fence closest to the operator.
