  David,
  According to Wally Brooks, Brooks LTD, the staple acts as a "girdle", =
helping to keep pressure pushing upwards.  His source of information =
comes straight from Abel.

Is that why the staples in the last set of Abel hammers I used has a =
noticable gap between the head of the staple and the felt?

The staple probably had some tonal effect back in the days when there =
was still some resiliency in hammer felt. It's been some time since =
we've seen much of that in production hammers.

I regularly pull them in the upper third to half of a typical hammer set =
so I can remove some of the excess felt most hammers come with.=20
