This time around I plan to create miter joints on the corners of my
stereo cabinet frame. I will also be creating a frame for a projector
screen and I plan to miter that as well. Not sure why since you cant
see it, but I got this miter saw so I'll get my wife to bring me a glass
of water while the wood is on the saw illustrating how valuable it is

anyway, I am wondering about the clamps. With box frame corners I just
clamp horizontally. If I try that with mitered corners the top will
squeeze out. I suppose if I had big enough clamps I could but 1 each
way, but I imagine that trickery would be too much for me before the
glue hardener... What type of *new tool* to I need to support glueing /
clamping these corners up? (admitedly if I can do it without a new tool
that will work too)

Thanks again!

No, will that be sufficient to ensure quality joint strength?

Absolutely, with one proviso--the miters need to be accurate (but that
would hold true if you use ANY clamping method). do a test fit with the
clamp and see if you see any gaps. Use a shooting board to correct them
if necessary.

OK. But I don't have a shooting board and I don't see any for sale. I
have an old rusty hand plane but I suppose I need to get the blade
sharpened somehow or just buy a new plane. Can I use my Dewalt miter
and hope for the best? The frame is not going to be on display. Maybe
if I cut some practice cuts to find that perfect 45 setting I can leave
the saw in place and just flip the wood for opposite side cuts?

It is a difficult one.
The very best way I know to clamp mitred frames:

Glue, screw or nail little 45 degree blocks on the outside of the frame near
the joints so that you can put a g-cramp directly across the joint and press
it properly together.

Does that make sense? If not I will draw it and post it for you on the
pictures group.

shooting boards are made, not purchased.

I use the LV band clamp with 90 degree corners to assure good joint
clamping. If your miter saw is set accurately, you will be good to go.

I've used rubber bands on small boxes. Don't know if you could easily
find ones large enough for your project. And the miters do need to fit
well, but that's true of any clamping method.

And there's always the old trick of sawing down through the joint to

G'day,
I band clamp is the way to go, but you do not have to buy one. You can
make a simple, but very efficient one with a rope.

Tie a rope tightly around your frame.
Cut 8 pieces of timber
Place 2 in the centre of each side of the frame between it and the rope.
Now by sliding the pieces of timber towards the corners of the frame you
will apply tension.
Measure for square cnr to cnr on the frame and adjust the blocks
individualy to make you frame square.
This method was the only one available when I started cabinet making and
it works well. Although I have a band clamp I still revert to the rope
trick quite often
Hope this helps
regards
John

If you are gluing the mitered frame to your cabinet frame you don't
need to worry about the miters. Just clamp the pieces to the cabinet.
Once the first one is down you can snug the next up against it.

wow, thats ingenious. I could pull that off. I may have a hard time
finding the rope. If the band clamp is not that cheap for the size box
im making (92" diagonal) then Ill use this technique. Thanks.

Looks like my best bet is to use a web clamp which I can get from lowes.
Only problem is the frame is about 80"x45" which is about 22'
circumference but the web clamp is only 15'. I wonder if I can find
some extra webbing at lowes. If I cant Ill use John B's technique.
Whats difference between a band clamp and a web clamp?

Second issue will be how to keep such a jumbo frame flat while I clamp
it. I don't even have a workbench yet. I suppose I could clamp it in
the driveway but im not excited about that technique. My wifes black
wooden table has become the defacto bench in the basement. She's slowly
starting to notice this, hehe. But this frame is bigger than this table.

maybe one of those old sheets of drywall in the garage 1 step away from
the trash will work out?

GET THEE A MITER SAW FENCE AND SOME STOPS

Work off the INSIDE dimensions for framing.

Cut the initial stock long

Miter one corner of each pair

From the "short side" of the first miter cut
measure and mark the INSIDE of the second
miter cut, preferably with a marking knife,
on the face you'll make the second cut on.
That'll be the "underside" relative to the
side facing up for the initial miter cut.

With the saw still at the first cut angle, flip
the part end for end, with your scribed line
towards you so you can align the part such
that a "keeper side of the cut" tooth's "keeper
side of the cut" is on your line.

Set a stop to the other end of the "keeper"
part.

Make the second cut on the first of the pair
for frame parts one.

Place the second part of pair one to the stop,
cut the first miter, flip the part end for end,
registering the first mitered corner end
against the stop and make the seccond miter
cut. NOTE: the stop must be square to the
fence and the sharp outer corner of the
first mitered cut has to be against the stop
NOT BEHIND IT - EVEN JUST A LITTLE BIT.

Repeat the process for the second pair of
frame parts.

NOTE: If the cabinet edges aren't square
things get a LOT trickier

Picture framers have a slick tool that uses
a "guillotine" (sp?) knife to fine tune the
miterer corners (see "Lion Trimmer" or
"Potlach") by slicing off see through shavings.
Hard to justify that tool purchase unless you
plan on doing a LOT of mitered frames.

Those mitered corners are not going to be very strong. If you can,
reinforce them with bisquits or dowels. Or use screws and plugs.

You can make your own corner braces; cut out 1 corner of a tubafour. Use
waxed paper to prevent glue from sticking to them. Use lots of clamps.
Practice the assembly before you apply glue. Good luck.

I've used several types of corner clamps but my favorite frame clamp
is the type that uses 1/4" all thread with slip nuts and corner
brackets. Size is only limited by how long a piece of all thread you
can get.
