Sometimes I find it awkward trying to hold parts in the vice, especially when using filing buttons.
So I just cobbled up this . I've probably seen this somewhere else before but can't remember where
drill some cross holes in a piece of bar, hacksaw a segment out, and file a vee on the middle hole,
Tap out one half and there you have it
quite easy to set up any way you want. saves trying to stand side on to the bench etc, although those with swivelling bench vices will wonder what all the fuss is about!
thanks for looking
