Which Alligator Squeezer shown below would you prefer to hold for HOURS at a time, performing precision riveting on aircraft structures?
Of course, it could be worse... You could be using the riveter shown below!
Numatx Inc. makes high quality commercial grade compression rivet squeezers, for the installation of solid rivets. Numatx riveters are the SMALLEST and LIGHTEST aerospace grade C-Squeezers and Alligator Squeezers you can buy. Numatx Squeezers also feature CONSTANT FORCE over the entire stroke range. The patented rivet squeezers are fully hydraulic at the forming head portion, which enables the squeezers to be more compact than traditional pneumatic only units. This reduces operator fatigue and improves product quality. Testament to this is provided courtesy of Delta Airlines below.
Company Award given to Larry Ashley at Delta Airlines Tech Ops, Atlanta Georgia:
"I would like to acknowledge Larry Ashley’s most recent contribution to Dept.383. Larry has labored to maintain the shops tooling as well as introduce innovative tools to improve the shops efficiency. This is especially true of a new hydraulic riveting system which has recently been introduced into the shop. Riveting titanium, steel and monel solid fasteners is always difficult and can be a dangerous job. The hydraulic system that Larry has incorporated into the shop, has made this job safer, more efficient and easier for the technician doing the job. An example of this is the titanium rivets which help secure the mount ring on the MD90 inlet. Previously a heavy rivet squeezer had to be attached to an overhead hoist, then the squeezer positioned awkwardly over the area where the 3/16 titanium rivet needed to be squeezed. The new system has eliminated the threat of physical strain and injury inherent with the old method as well as reducing the time it takes to do the job by two thirds and creating an improved finished product."

Commercial users of Numatx Squeezers include:
Shown below are NXA-6 / NXA-10 Alligators and NXC-6 / NXC-9 C-Squeezers in use at Northrop Grumman on the E-2E Hawkeye.
Shown below is the size of Numatx C-Squeezers as compared to a traditional 3,000 Lbf (3K) pneumatic only C-Squeezer. Note that the Numatx NXC-9 9K (9,000 Lbf) Squeezer produces 3X the force of the traditional 3K Squeezer, while being 2 inches (51mm) shorter and weighing 1.75 Lb (.80 Kg) less.
Shown below is an NXC-9 9K Force C-Squeezer and NXI-40 Pressure Intensifier.
Shown below is an NXC-6 6,000 Force C-Squeezer (bottom) compared with a traditional 3K pneumatic only C-Squeezer (top). Weight of the NXC-6 without a C-yoke is 1.7 Lb (.77 Kg).
