Rivets

["Keith Turk" <kturk@ala.net>]

Just curious if anyone has a favorite source of rivets.... not pop rivets...
but the one's you hammer in place..

My buddy's building an airplane and I needed to reinforce an area of the cowl
on the race car... so I borrowed some from him and all his tools that make
this a Very cool deal... but his supply of rivets didn't include the length I
needed...

Also just out of curiousity... anyone have the exact length they should stick
out prior to hammering?
