What tools are folks using to rivet new fan blades on old hubs?
Find a good buck and a ball peen hammer. Then be careful you don't break the casting.
I use my CLECO 7X rivet gun and rivet sets with a steel bar in the vise.
Check the thickness of each individual blade. My buddy bought a "set" a couple years ago, riveted it all together and it shook violently when he started the car. Turned out, each blade was made from a different thickness of metal and was WAY out of balance.
John, If you have a good radiator, and keep moving, a fan is not needed. You might consider not running one.
Oh....just leave a rivet or two out of the heavy blade.
But Mike, how will he keep his water pump turning without a fan belt? ;o)
