I am going to head to a fairly large tool auction in about a month, and I am going to be looking hard at the jointer planes. I’ve read that it’s really hard to flatten an out of flat jointer bed. Should I take my metal straightedge and feeler gauges? How close to flat does it need to be? Since it’s an auction and no takebacks, I want to avoid a lemon. Any suggestions would be appreciated.

I would expect it to be fairly flat across heel, mouth and toe. In antique stores, I use a flat surface like a display case top to check it out. You might be able to use a Table Saw or jointer bed to check it if there is machinery there.

Good advice from WayneC. I usually bring a small square and a tape measure with me when I’m rust hunting, along with eyeglasses to see small markings and/or hairline cracks in castings. The square has helped me avoid bringing home a bunch of lemons.

I would suggest that you take a 24” straightedge with you and check the diagonals on the sole. As long as you can’t see daylight for the first inch, about an inch on either side of the mouth and the last inch or so of the tail, you’re good to go. It is a MAJOR PITA to flatten a jointer, but as long as you’re “in plane” on the 4 points I mentioned, it will work fine. I would also look at how well the depth adjuster and lateral adjuster work. Good Luck!!
