The WOOD plan specified two 3/4'' diameter magnets. Most likely, some magnets are better than others, but two wasn't enough! I used a stack of three 1'' magnets on each end, and two stacks of 3/4'' magnets in the center.
The magazine plan specified #8 wood screw to hold the dial-indicator in place, but it did not work all that well for me. I used a 1/4'' lag bolt with a wing nut instead.
From WOOD magazine October 2005. My old Walker-Turner jointer does not have jack screws, so I used the Jointer Pal jig to install the blades. This jig will be used to confirm the blades are adjusted to the correct height.
