differing holding strengths for differing materials. (roof shingles take a
1" crown for example)
Fencing can use a 1/2 " crown
lesser noticeable penetration holes-smallest crown- finish work

if staple is shot with the grain it may penetrate too far.
if staple is shot cross grain it causes more distortion in wood product.
(plywood it does not matter in this case) straight grain wood does matter,
and cross grain shot produces more
damage to face, with grain shot may penetrate too far, and I like 45o angle
shot that grabs grain, and is less damaging to surface.
just a few thoughts on staples.

I thought there was only type of air crown stapler: narrow crown
stapler. But I come across something called a medium crown stapler. I
guess the staples for medium crown stapler is slightly wider than
those for narrow crown stapler. Other than this, what is the
difference any way? Why someone will use one over another? Does a
medium staple hold the wood parts together better than a narrow
staple?
Thanks in advance for any info.

Narrow crown staplers only use narrow crown staples, similiarly, wide
crown staplers only use wide crown staples, the same goes for medium crown
staplers=medium crown staples. Maybe you really want to know the
difference between the staples and not the staplers.
*Wide Crown Staples* - Wide crown staples are typically large, heavy-duty
staples. Theyre mostly used in applications where the staples just have
to work, without looking pretty. Theyre used in construction
applications, such as roofing, house wrap and truss construction.
Theyre also used for furniture frames and cabinet frames, and
carton-to-skid attachment in packaging.

*Medium Crown Staples *- Medium crown staples typically have more uses
then their wide crown brothers. They play a big role in home construction,
as theyre used for cedar shingles, fascia and soffits, fencing, floor
underlayment, and siding. Like wide crown staples, they too can be used in
furniture and cabinet frames. Theyre also used in pallets, crates, and
boxes.

*Narrow Crown Staples* - Narrow crown staples have a narrower scope of
where theyre used, but can be used in more €œdelicate€� applications,
like installing moulding, trim, and lattice. Theyre used in cabinet and
drawer making, as well as for fascia and soffits. Their narrow crown make
them more easily hidden than their wide and medium crown brothers.
