Object framing

[GRIFF]

Trying to attach a heavy transparent plastic plaque onto mount board which will form part of a box frame.
The plaque is 5"x7" and 25mm thick.
I can't use silicone since this will be seen through the transparent plastic.
The object holders ( 2772 ) in the Lion Catalogue would do the job but these are only 12mm and 7mm thick.
Would appreciate advice.
Thanks

Hello Griff,

Formed rods may be an option, couple each top & bottom painted white, see this example http://theframersforum.com/viewtopic.php?f=6&t=9239

Double-sided foam tape will hold it. Only snag is it is thick and will create a gap, but that could give you a nice floating effect.

I once stuck a flying multi-socket thingy to the back of my hi-fi cabinet using this tape. Years later when I wanted to remove it I couldn't prise it off even using all my mighty strength. And that was plastic to varnished wood. I had to slip a hacksaw blade in the gap a saw the bugger off.

Croeso (welcome) Griff!

Is it rectangular and flat on the front? If so I'd have to give clear film (Melinex/Mylar) a go.

Cut a piece of mount board the same colour as the board it is to be mounted on (or a contrast if you like) ever-so-smaller than the plaque, then make two straps that cover it completely, one horizontal; one vertical, Wrap one around and fix it to the back of the piece of board with double-sided tape and then wrap the other around that and fix ditto. Glue the board, with plaque held to it, to your mounting board with anything you like.

Or, to cover with one piece instead of two, cut out a cross of film with the centre the exact shape/size of the plaque and wrap the 'legs' around on to the piece of board. The legs could be the same width and length of the plaque or not, but the wider the better.

Hope that makes sense, and pob lwc (good luck).

Roboframer's solution works for me too, but I would not rule out a tight fit cut out in a piece of plastizone covered with mountboard. Plastizote is available in a wide range of sizes and thicknesses in a small, or large quanities from many different of suppliers.

I'm waiting for my first chance to use plastizote. I think that it will soon become another standard object mounting technique.

BTW, if you haven't used Mylar / Melinex film before, this is a good time to start. It is such useful stuff for a framer to have in his / her workshop and so easy to use, once you have learnt the techniques.

A 'tight fit' would mean sinking the thing - and then probably having an aperture mount cut smaller than the thing to prevent it falling out of the sink.

The 3-dimensional look would be lost.

Formed rods, acrylic gizmos or a clear film wrap would not lose the 3rd dimension, and out of those 3, for something already shiney, the clear film wrap, if it would work, would be the least conspicuous.

I was thinking of sinking it in by only 5mm. That would give it a lot of lateral support and then I think that you could get away with much more minimal width of melinex straps, so hopefully much less noticable and the plaque still sticks out by 20mm.

[Roboframer]

A strap would be more conspicuous than a complete wrap - in fact if done right you could challenge anyone that didn't know how it was done to work it out and they probably couldn't.
