Cutting / measuring odd angles for miter cuts
 

Hoping someone can give me a tip about how to get good cuts for
quarter round molding where the angle is greater than 90 degrees. With
a normal corner I have no problem cutting the 45 degree angles but I
have a wall that has a bend/corner which is more like 135 degrees
(just guessing). What is the best technique to get a good miter cut
for quarter round in that corner. I have never used a coping saw so
I'm hoping there is a simpler way to measure the angle and make the
cuts with a miter saw.

Thanks for any advice!

If you have to do it with a miter the easiest way to do it is to take
two pieces of stiff paper, lay them on the two walls at the corner,
then draw a line along the edge of the one piece of paper on the other
piece. Then divide that angle in half with a compass and straightedge
and use that angle to set your miter box.

Vic-

For molding, the "correct way" for corner joints is a coping saw (but
it's one detail of finish work at I'm to lazy to do),

wrt to greater than 90 deg "miter" cuts......use a square cut chunk of
2x4 as a 90 deg block and clamp it too the miter saw fence. Place
the 1/4 round against the block and set the saw at 45.

It's a little tricky when the "round" face needs to be against the
block.

cheers
Bob

Inside or outside corner? I've made 22 degree +/- cuts to get around
bullnose corner bead.

Even look at the book while at the orange store.

Here is a suggesstion that works: Half of your corner angle is 135/2
= 67-1/2. Use a 1x4 scrap piece of wood and a mitre saw to shape a
right traingle jig with a 22-1/2 degree angle (meaning the triangle
will have one 90-degree angle, one 22-1/2 angle, and, of course, one
67-1/2 angle). Next, place the jig against the mitre guide with the
22-/12 angle butting at the blade slot, set the blade at zero, and
prop the1/4 round against the jig. Viola! You have a 67-1/2 mitered
angle. If the corner is not exactly 135 degrees, you may want to
adjust the angles of the triangle until you end up with a good fit.
Alternatively, you can go to HD and buy a protractor that will allow
you to mitre any angle. HTH
