Low profile, compact work-holding solutions. Advice sought.

Maybe you could machine a shallow pocket in wood or perspex then fit the workpiece inside it, held down with double sided tape in the bottom.
Nice job by the way.

Cheers Eddy - yeah, I was leaning that way - although a micro DIY vacuum chuck might make a nice project... Will look into it a bit further to see if it's something that I could manage...

Clive S made a very good point earlier - I'm losing 20% of holding strength by using only the 1 strip of tape and leaving part of the blank 'unstuck'... Never really stopped to consider it, but when written down in numbers it becomes a lot more obvious!
