just as the title says... this is a quick how-to on making 45* corners...
get a piece of material, i use 3/4" MDF.. make sure it is at least the length of the inside height of the box.
next, i use a combination square to make my cut lines at 45 degrees..
make sure the lines are perpendicular, of course..
set your blade angle at 45 degrees, and set the fence accordingly..
line the blade up with the cut lines made on the end of the piece, and lock the fence in position..
carefully rip the piece down, using push sticks if necessary.. the piece should now look like this..
the next step will differ, depending on the saw you are using. the saw i use only tilts the blade one way, so i have to flip the piece accordingly to make the next cut..
the piece should now look like this:
now, if the piece was longer than the internal height of the box, put it in a corner, and mark it with a pencil
trim the piece at the line you made... then glue and clamp into place..
keep in mind, when making corners for port walls, to measure before making the insert. make sure port width stays equal from one end to the other, corner inserts may have to be made wider or thinner to keep width equal.
I know this may seem like common sense to most.. but i have been asked a few times on other boards by a few members to post tips on how to do it.. i thought id share it here too..
