Double frames - same depth at back

[pramsay13]

I have framed a canvas with a smaller frame used as a slip. At the back they have both ended up exactly the same depth so I can't use points to fix them together.
Any ideas?

glue

Staples

Melinex straps in a figure if 8 configuration , interspersed with pure cotton

Or use flexi points?

Or flatten out 3mm canvas offsets and use like a big turn button

I was serious about staples, it's what I use, they just bridge the two mouldings.

I usually rub off the finish in a couple of spots and put a dab of pva in there, I make the inner frame quite tight and have been known to shoot a few staples in there too.

Sorry mate

It's not a default method for me though and nor is points and staples, I usually use offset clips and these are handy for this situation http://www.lionpic.co.uk/product/SPRING ... 212,0.aspx there's various types.

Narrow crown stapler, or brad nailer works for me. I make the two frames a snug fit and usually I think that gluing is not required! Keep it simple and save valuable time!

the main reason for gluing is...

the second frame won't be flat to your bench when yo put the picture in, it will only be supported at it's furthest point by the lip of the first frame, whilst clipping in the picture any pressure you push down with can cause the inner frame to twist downwards and crack the corners (especially if some of your employees are a bit heavy handed at times) giving you gaps on the inner frame, gluing will prevent this, and will take less than 1 minute to do so time is not really an issue on bespoke jobs and will save you having to re do it if it does crack.

If the liner is fairly narrow, I drill pilot holes from the inside and use veneer pins. Don't need them too long - about 1/4" into the outer frame is good enough. You may want to remove the liner again. Which is why I would NEVER glue them in.
If the liner is too wide to nail though, toenail it by drilling near the edge at an angle. If the two parts are around the same hight you can get a round file and make a few little scoops along the edge so you can fire points in. Nails are neater though. Hammer and punch is all you need.

Thanks all, I've put in semi rigid points at an angle and bent them back slightly. There isn't a lot of weight as there is no glass so these seem fairly secure.

I've used tiny mirror plates in the past, two screws in the outer frame, one in the inner ( or just leave an empty hole) You have to have a decent width outer frame, obviously, but it works.

Flexible brass plates?
