HF Punch and Flange (pneumatic)

[superkaz661]

Anyone have any experience with this piece? http://www.harborfreight.com/cpi/cta...temnumber=1110

I'll be replacing the floor pans in a car I'm restoring, and I thought this would come in very handy. I'm a little apprehensive about its claims to be able to work with 16 gauge. I have a set of HF metal shears that is rated for 14 gauge, and I have broken those jaws twice after about 20 linear inches of cutting 16 gauge.

Any opinions?

I should add that I'll be fabricating a shallow tray for the floor pan to sit in (I need the extra legroom) and rosette (plug) welding in the 16 gauge floor to the 20 gauge tray. I think the punch would be great for making the rosette holes and the flange while not absolutely necessary here might be nice should I need to do body skin (which I likely will have to do)
