I have been replacing the lower right half of the cab and floorboard lately. WAY too many patch panels invested in so far.
But, I bought the air flange/punch tool from HF last Friday and used it all weekend. If it only lasts the weekend, it will be worth the $39 I paid for it. It worked great! Punched holes so I could do some "spot" welding, and flanged existing good metal so an amateur like me could match them up while welding.
They offered me the 2-year guarantee (for extra of course). I told the guy that if it lasts through the 90-day standard warranty, I will have gotten my $39 out of it.
Highly recommended. Oh, and I am using it with a portable DeWalt small air compressor. Doesn't do much more than 16 gauge (and that with a few presses of the trigger), but all my patch panels were that thickness.
