No argument that the more expensive guns are nice tools. But the H-F 3/16 gun was adequate to build my Fokker D.VII replica which is a riveted tube-n-gusset airframe. The key to getting good service from the H-F gun is to carefully adjust the pulling mechanism. This is not a difficult operation but makes the difference between operating smoothly or being frustrated. I agree that two of these inexpensive guns would be a nice combination.

Sam,

Is there a guide on how to adjust the mechanism? Adjusting mine has never crossed my mind.

My third HF gun has performed without a problem. The first two went back to HF and were immediately replaced.

Now, if I'd have picked up the third one first..............

What is the best type of hydraulic fluid to use in these pneumatic pop rivet guns?

Kyle,

Here is a photo showing the inside of the H-F gun:



The position of the black collet on the threaded shaft determines how tightly the rivet nail will be gripped. The lock nut can be loosened to adjust the grip. This is a very fine adjustment, too tight and the nail won't be released, too loose and it might take more than one pull to set the rivet. The collet needs to be adjusted in small increments until the rivet is set smoothly and the nail released. This is also a good time to clean and lightly lube this assembly.
