Pneumatic rivet squeezer with 3", 4" and longeron yokes. Includes adjustable set and quick change pins.
Purchased new from Isham/Planetools.com in early 2011. Used to build the horizontal and vertical stabilizers -- maybe 200 rivets squeezed, if that many.
I'm not sure of the manufacturer's identity, but the squeezer and yokes are made in the USA. The squeezer is also the same version sold by Cleaveland Aircraft Tool and Aircraft Spruce.
My son was born in late 2011 and, you know the story, the building stopped. Been stored in a climate controlled basement since that time.
This set runs about $1,000 new. I'll sell for $895, including shipping within the continental US. Willing to deliver/meet within reasonable distance of Omaha or Kansas City. I live in Omaha, but will be in KC for the upcoming holidays.
12/5 Update... I'm adding the rivet sets you'll need to the package...
