Thread: biscuits

I am ashamed to admit that I watched a show called DIY tools and techniques on foxtel the other night. Very lightweight stuff. They basically go through the absolute basics of a whole range of tools etc.

Feeling very proud of myself for knowing all this stuff, I thought I'd keep watching a section of biscuit joiners. All the basics were fine, until the host started talking about different types of biscuits.

There are clear plastic biscuits for joining translucent products, hard plastic biscuits with ridges for 'hard to clamp' projects and aluminium biscuits for to enable projects to be disassembled. See the attachment

I can't really understand how these work. Surely they need the glue to expand to hold them in? I can understand their use for alignment etc, but I can't figure out how the aluminium biscuits stay in the slots.

Anyone heard of these or used them before?
