the top panel of the jewelry box

as you remember when i cut the rough wood to rough dimensions, I cut the top (the panel) and wood for a mitered frame around the outside.  the biggest issue is to get  an exact 45 degree angle for the miters.
forget the expensive miter gauges. this is best done by hand, trial and error to get it perfect. Thanks to Lance Patterson ( he thought I wasn't paying attention)!

the basic premise is to set the table saw either the miter gauge or tilting the blade. i prefer the blade tilt.
cut separate 45 degree cuts into 2 boards, making a long and short piece.Then match the miter on the two long pieces. even if the machine says perfect 45 it will NOT be perfect. take your sliding square and check the inside for square.  the reason its not, is because we are introducing double error precision. if we only made the cur once and checked it may be off by 0.5 degrees. this way, the miter will be off 1 degree. adjust the machine to make the miter perfectly square.

OK back from the technical tangent.

here are the miters cut and the panel pseudo in place: balanced on the top of the carcass.


one note here, nothing has been glued not attached. all this is cutting and checking for fit and square.
once the glue goes on, its really hard to make a dado or whatever inside!   Again, I have only heard mention of this problem just a few times.  oh yes that was me!

a side technical note, if you ever happen to do a glue-up, and say rats!!!! alcohol dribbed into the joint repeatedly, with pressure from a clamp forcing the pieces apart, AND a strong heat lamp, you might get the satisfying crack or boom after 30 minutes of work. This is for yellow glue and hide glues, epoxy's and others, you are done. glue has set.done. you might as well think of another means to cut those dadoes inside.
