Hold down clamps, what do you use?

[Web Goblin]

I had been toying with the idea of making my own clamps and after much looking at what was available on the market I decided to modify something to suit my needs.

This is what I have came up with.


They are cut from 25mm thick aluminium and should be able to suit differing thicknesses of material. Although not quite finished yet Im sure you get the idea.

So what do you use? Readily available kit or have you came up with your own?
