    I have a lot of trouble squaring even small pieces of wood I’ve tried using a shooting board but still no luck. What also baffles me is I can get three corners square but when i check the fourth corner its off. The only thing I can imagine is; could the three corners be off very slightly and the error only shows up on the fourth? Ive watched Pauls wood prep videos. Any other suggestions would be greatly appreciated. Cheers!

    Sounds like your corners are square but one of your sides are not parallel. Try running a tape diagonally across the cornersto see if they are the same would be my guess

    If your registration square shows 3 corners on and the 4th off then the registration square is likely off. If 3 corners are 90 degrees and your edges are straight then the 4th corner must be 90 degrees. If you planed a taper into the 4th corner then it could be any angle but a straight edge should show whether all 4 edges are straight.

    For instance if your square is really 89.5 degrees then 3 corners could ‘look’ square but the 4th will be 91.5, a full 2 degrees off your registration square (91.5 – 89.5).

    I’d check your square for accuracy, if your shooting board was made using that square then it’s likely off in the same way. It can be checked by shooting two boards, putting them end to end with one flipped. If they describe a straight line the shooting board is square, if they describe a V then it’s off by 1/2 that error.

    If they describe a straight line the shooting board is square,

    For one of the orientations, don’t you have complementary angles, so, if you get a straight line with this test, mustn’t you flip one of the boards over and *still* get a straight line (rather than a gap) before you can decide? Of course, to test just the square rather than the shooting board, you just need to knife a line with the square on some scrap wood, flip the square, and knife another line.

    @ed, correct, I struggled without how to phrase that without getting confusing so just settled for saying ‘if you flip it and it’s straight’.

    But yes it really needs to be checked in both orientations, flipped and not flipped to be 100% certain since one orientation is guaranteed to be straight due to the complementary angles as you say.
