You'll want the smaller nose pieces, so I think the 3/16" is what you want.
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.
Sam,
Is there a guide on how to adjust the mechanism? Adjusting mine has never crossed my mind.
I got the Chief from harbor freight, filled it with hydraulic oil, and when I pull a rivet it blasts oil all over my part. Anyone know why this might be happening?
When you say “filled it”, what do you mean? How much oil? I’ll be honest - aside from lubing the jaws, I never put any oil in my HF, or two Taylor guns, and have built two pulled-rivet aircraft with them….
