Guys, I’m working on a project which has 60 degree roofs which are about 7” long and 4+/-” wide, they have been pre-finished and I would like to glue them together but my clamps keep sliding off. Its across the 4” peak I want a tight joint.

Could you put a couple pin nails in it until the glue dried? I’ve never had a lot of luck with pre-finished pieces holding together with just glue. But could be the glue I use.

Make a jig and glue them upside down?

I would do it with wedges in a square box.

If I understand the problem correctly, this is how I’d resolve it.

The green part represents a piece of plywood with an angled block glued to the top. Two of these get clamped to the birdhouse top then clamps are placed across the angled blocks to close the joint.

Sandpaper is normally what I’d use as the non-slip substance on the piece of plywood that contacts the birdhouse top. On a finished surface you may choose to glue non-slip rubber drawer liner there instead.

Basically the way clamping works, if you can provide surfaces parallel to the joint being glued on either side, you’ll be able to clamp across the joint perfectly.

Mark, the pieces were only finished on the “good side” I don’t think the birds will care if there roof is finished on the inside. LOL I used the pin nail method to do the ones in the pics but they are not as tight as I would have liked.

Jaaune, I like this method and I think ill just make it a little longer and glue a block on the bottom as well to stop it from lifting. Thanks for the suggestions, this place rocks.

There are some creative and practical solutions offered here. And then mine, way less drama and cleverness:

I’d lay these good side up, pointy edges just touching, and tape them together with masking tape.

Turn it upside down, spread the glue (an acid brush is very helpful in this situation) and fold it together. Results are amazing.

Kindly,

Lee

I agree with Lee and James 101.

Miter folding is easy and effective. Use some good packing tape, not masking or painters tape.

Yep, masking tape. Simple and effective.

Thanks again for the suggestion, when I do a more precise project I think this will come in very handy. These pieces were rough sawn and aren’t consistent enough to get great joints.

A little flagrant hijackage here, regarding tape types.

I have used masking tape because it is actually stretchy. If I put a little tension on it as I’m applying it, there’s pull involved.

I’m interested in packaging tape too—would it have other advantages?

Now back to the OP: If the cut’s aren’t so good, two other adhesive choices would be epoxy and polyurethane.

Kindly,

Lee

They sell a clamping aid called “Blockz”. I think Lee Valley/Veritas sells them now. Comes with rubber liners for not marking finished pieces.
I would use a domino , biscuit or dowel to strengthen the joint.

I would use masking tape or packing tape.
