Hi all. I’m gonna be glueing up a lot of miter cuts soon, and want to know the easiest/best way to do so. I’ve heard of glueing “ears” on the outsides, and frankly I’m very scared of gluing it incorrectly or too much and it becoming part of my work piece. Is the picture shown below an acceptable way to do this instead? The project in question is a jewelry box.

Strings and shims
#1052277182736629780 message
To answer the second part of your question, those blocks will hold things square, but they're not helping solve the problem of putting clamping pressure on the actual miter
So something like string or strap clamp or spring clamps like these are what you want
But just do the string. It's dead simple and you probably already have everything you need
gusty rover
are the shims on the corners just ot keep the string off the glue?
mild trail
Nope, you insert them in the middle of the side and then slide them towards the corners. It focuses the clamping force on the corners
gusty rover
ah, neat, thank you
I think I'll use a combination of the string and my corner clamps to make sure things are square. Looks fiddly but I kinda signed myself up for that when I decided on doing a bunch of miter joints. Never again.
mild trail
I wouldn't bother with the corner clamps. Take the corner to corner measurements and if one of them is longer, put a clamp across those two corners and apply a little pressure
gusty rover
Noted. In the picture you provide, what is the purpose of the clamp that is "standing up" with its jaws facing downward?

Looks like it’s holding the tourniquet?

Yepp ^

Same thing basically
gusty rover
Are you familiar with how the windlass works in a tourniquet? I was planning on doing something similar. Or is that exactly what the pic shows and I'm just missing something?
was gonna take a shim, drill a hole through it, tie the string around the box and through the hole, and twist the shim with the hole until I like the pressure, then clamp the shim down so it cant unwind
also, would something like this apply force to the joint, or just do the same thing as what I showed, only ensuring square and not applying clamping pressure?
cursive grove
I think that’s just for square
And I’ll defer about the tourniquet question. It sounds like it would work but be more complicated than the standard way
gusty rover
Ok, fair enough. I'll practice on a dry fit a couple times first regardless.

what happened to ears
gusty rover
I’m a baby that’s scared of glueing stuff to the outside of my work piece
hardy sparrow
if you have hide glue, you can just put a little newspaper between the ear and the piece
it doesn't need to be strong the clamp the miter and then just pops off
gusty rover
Was going to try something like this
No hide glue for me unfortunately, I’m a PVA pleb
hardy sparrow
that's a way to make the same thing more complicated, yes
it's going to slip in the middle
might be good enough?
I'd test the paper weakened ears on scrap first
gusty rover
Does the paper trick work with pva glue as well? I also gave some though to just getting some ears with rubber glued on them
hardy sparrow
I use pva when forced, so I'm not sure
the hide glue cleans up nice
fear is the mind-killer Bugzby
gusty rover
Just whipped up some material to do the jig thing I showed. If it doesn’t work, I’ll live
Hoping pva can hold particle board together
mild trail
Are you going to reinforce with splines?
gusty rover
I’m not sure what you mean by that
Like a rod through the material so my clamps don’t shear my glue line apart?
This is what I have going currently

So unless you're doing them in some very bizarre way, they are very much structural.
They're a way to reinforce miters with some long grain glue surface. People just think they look nice as an added bonus
gusty rover
alrighty then
Really I just added them as a way to locate my box a little better to help me line things up
mild trail
At the risk of throwing too many options at you, have you seen the blue tape trick for miters?
gusty rover
I have, yeah. Was also considering that. Is there a hierarchy when it comes to this kinda stuff or is all pretty much on equal footing?
hardy sparrow
Strongly in “you do you, boo”
gusty rover
QP, when you say the middle will “slip” with the example pic I sent, what do you mean by that and would it still be true if my box is only about 5 inches tall?
mild trail
There's a ton of factors including how much I care about the miters being perfect, how fast is the method, how fussy is the method, etc.
End of the day you just need to try things and see what works best for you
hardy sparrow
Wood is flexible but maybe less so with your particle board
The issue is without being secured in the middle it’s going to be hard to direct the clamping force
I’m speculating so I don’t know if 5” is enough to mitigate or not, apologies
gusty rover

Yeah gonna try what I have cooking up tomorrow and hope it goes well. Thankfully the person the box is for is way less fussy about details than I am so small imperfections that I can’t fix will only bother me when I see it in their house
gusty rover

Oh gosh, don’t apologize, I’m just an idiot playing around in his garage, any and all speculation is far more valuable than anything I could drum up on my own

I relate very much to the above statement
gusty rover
Lol yeah. Being in the same community as people who actually know what they’re doing keeps my humbly in the bottom of the Dunning-Kruger curve in a way that college never did
mild trail
I relate very much to the above statement
So do I and QP too if I had to guess

ear, paper, glue, workpiece ?
or ear, glue, paper, glue, workpiece ?
Maybe it'd soak through? I presume it's to stop the wood fibres getting all cozy so you can split it without destroying the grain?

I think ear, glue, paper

I find that hard to believe!
