How do you clamp wood at a 45 degree angle?

Question

I'm building cat perches inside of my screened porch. I want to come off of a stud at 45 degrees, then another 45 degree riser. But how do I clamp that 45 degree joint?

Answer 1

You need to make a jig to "fill in" the angle and make it 90 degrees so you can clamp it all together OR just use long screws in conjunction with glue.

Answer 2

While # 3 offers an extremely valid suggestion in a CORNER CLAMP, so often used in frame making, it seems unlikely it would work in this case.

  # 2 offers a suggestion I use, but in your case since it isn't two flat pieces of stock butting at a 45, you may have to cut another at a 45, with a surface perpendicular to the stud, forming a square to clamp to.

   What I'm more curious about in trying to visualize this with no image, is why the need to clamp? Couldn't you use a perch piece large enough to cut a "birds mouth", allowing two surfaces to connect with the Stud, then angle brackets under for support and attach points, OR make a cut that allows long drywall screws?  I have built more than one cat tree, and at a weight of sometimes 10 pounds, I'd add angle brackets always for stability.

Just my two "sense"

Answer 3

This may sound obvious, but you use an 'angle clamp' like this one...

If I understand your problem, this:

If you don't want to spend the money for a one-time tool, you can fashion the same thing out of some scraps of plywood.  Drill 1" holes for the clamps to fit into.

Answer 5

place a clamp at lower end of ramp on the stud ,the ramp wont go any where..
