So I’m in the middle of a project making a picture frame using my router, but more about that when it’s finished.

So I tried to use my band clamp to keep the 4 sides of the picture frame at a 45° angle and was having a terrible time so I when online and found this great I idea of making your own frame clamps out of scrap wood. Below is a sketchup model of what I made.

You basically need the following.
12” of 1×6 lumber
A speed square to find the 45° angle of the pieces.
A jigsaw to cut out the inner frame clamp this leaving the outer frame clamp

The only negative thing about this method is that if your making small 4×6 picture frame you can only clamp the top corners simultaneously and then will have to clamp the lower corner after the top corners have dried…

If you have any ideas on how to clamp all 4 corners at the same time I’m all ears…

Ed,

I’ve been trying to think of how I would solve this problem. I tend not to be in a hurry with my projects, so I’d probably use your clamp idea, but I’d glue opposite corners, not adjacent ones. That’s not much help, but that’s how we glue together model railroad structures when building from scratch.

A thought: It’s not my style, because I don’t have this kind of glue, but I can imagine using CA glue with a quick set spray to make things go faster. It’s pretty much instant.

Thought #2: You might want to nip the corner off the ‘internal triangle’ to prevent it getting glued to the frame.

Ed,
I’ve always used the band clamp in conjunction with exterior corner blocks similar to yours, though not as large. Sometimes I need to adjust the blocks during initial tightening. The glue up should square up but some pushing and prodding is necessary. Of course, if your bevels are not exactly 45 degrees or adjoining faces not complimentary to 90 degrees, then no amount of clamping pressure will fully close the gap on the fourth corner.

Looks like these would work like a charm. I agree w/Dave about the inner triangle tip. By nipping that corner, the glue squeeze out has somewhere to go

If you have any ideas on how to clamp all 4 corners at the same time I’m all ears…

Can’t you just cut out a smaller corner from the blocks? For example, if you have a 4 inch inside dimension, you could just make sure your short sides on the triangle are less than 2 inches. Another idea would be to nip the corners off the triangles. Based on your Sketchup drawing (side c=4) and the Pythagorean theorem, your short sides (a & b) appear to be 2 inches. Just knock off the corners where a & c meet, and where b & c meet. Alternatively, include Dave’s suggestion and cut off all the corners.

Does that make sense? Is it helpful?
