Handy tip on holding down thin sheets of material.

[dwc]

Another method more suited to milling thin sheet metal objects is to use a cyanoacralate glue

In my experience this is only good if there are relatively large surfaces involved for the glue. 
I have been milling watch hands recently and have ended up using cyanoacrylate glue AND tabs.
Alone neither one held well enough.

Note that this glue is Gods gift to watchmakers.  Making parts you can hardly see, we are always gluing them to something bigger to hold them and it unglues just as fast as it glues.  In general the low viscosity types glue and unglue faster, but I see no particular difference in their holding capability.

Don, you might try the black rubberized CA glues.  They remain quite flexible compared with 'normal' CAs, with excellent bonding.

Bob Smith Industries makes it, and Hobby Lobby and their ilk sell it.

As long as the surfaces are smooth and oil free the 3M Double sided tape cannot be beat in most applications. Back in my working days I often machined compounded angle shims out aluminum. The sometimes thinnest edge to be .005" and the shims often were about 12" long. You could not take a heavy cut but by being careful it worked really well. For bigger sizes out of SS ended toe clamp it cut bigger size and trim to required shape. Hope this helps someone.. Here is an webpage. You maybe able find more info.
