reinforcing miter joints

[Dan Barr]

wondering if anyone has a good method for reinforcing miter joints without the reinforcement being visible. (spline joint not an option here.)

see the attached.

thanks,

dan

How wide are the mitres, Dan? You might be able to dowel or biscuit them.

I'm really getting back into biscuits big-time.

How about a halflap mitre?

Domino, keeps the joint aligned during glue up too.

I've just seen (latest copy of Canadian Home Workshop) where a biscuit can be inserted across the back of a miter joint to reinforce it. The excess is cut off once the glue has dried. Looks like a great idea.

Secret miter dove-tail. You can find out how in Ian Kirby's "The Complete Dovetail" book. It's the most complicated of the 4 types and not easy to explain without illustrations.

Sarge..

I've been using a different approach. On my last project and the one I'm working on now I've used Miller dowels as a decorative way to reinforce the miter. It may not be the best way to do it, but I like the results.

How about a halflap mitre?

Believe or not I cut after over 25 yrs of WWing I cut my first one of these today, relatively easy and you can't tell the half-lap from the front or side; but it is visible from the top/bottom and back. Overall this is a very attractive and strong joint.

You could inlay a spline on the bottom edge of the joint, where the bottom edge of the mitered face is covered by the spline but inlaid so the spline is only visible from the bottom.

[Dan Barr]

would a butterfly or bowtie (double dovetail) on the underside actually reinforce this joint?

the dimensions are:

rails are 2" wide and 1 1/8 thick (on edge)

ciao,

I can't see Dan's image So much for paying in my six bucks

So what kind of image is that Dan??

[Danny Thompson]

A .jpg. Here is another option, plus a powerpoint version. Option 2 is essentially a loose tenon glued into a hinge mortise that spans the miter.

that s&cks that you cant see it.

just a bitmap line drawing of a miter joint.

thanks,

[Dan Barr]

im going to go with the inlaid spline or the bowtie/butterfly on the underside.

thanks,
