A Vise Jaw Extender

[tonyfoale]

I often use pieces of wood on top of the table, as much for quick spacing as anything else, although essential when using a holesaw, but I rarely do that when holding work in a vice. Most times I align the hole position with the slot down the centre of most vices. Sometimes that is not possible with multiple holes or the shape of the workpiece and only then do I use some wood. That's when Rick's solution would work for me, usually I find that I have to bandsaw a piece specific to each job.

I can honestly say that i have never drilled an unwanted hole in a vice or drill table but much to my continued annoyance I did cut a groove in my mill table when a cutter pulled down. That must fit the "legitimate accident" category mentioned by toolmaker51 but it still hurts each time that I see it.
