SIMONIZ POPS A DENT

[Free Citizen]

Hello Repair Gurus,

 

Not that I am suggesting that this will work with dented and dinged barrels and caps. But I was just wondering if a tool like this could be made to work with pens?

As a person who has restored 2 classic cars, I have used these sytems and can tell you it probably can't be used on a pen. It is really made to pop indentations out of thin sheet metal. It works by hotglueing a shaft onto the middle of the dent and then connecting it to a plastic bridge that has 2 suctions cups on each end. You position the bridge on an adjacent undented portion of the car and then screw up the shaft and the dent pops out!! Sometimes!!

 

Metal shafts on pens are too thick and the system is really not made to work on anything less than 2 inches. Nice idea though.

Geez, if that would work I could have saved a pile of dough and a few years...

 

As pointed out, the ratio of material thickness to the area of the dent is on a completely different scale with car body dents and pen part dents, as is the typical radius of the part, as well as other factors. The natural restoring force is insufficient to overcome the countervailing forces induced by the deformation in order to create the critical 'pop' action that is responsible for the efficacy of the pops-a-dent method.

 

But don't think I didn't investigate it, as I did with virtually every other dent-removal technology from a variety of disciplines. And the research continues...

Where was that SIMONIZ POPS-A-DENT when someone drove into the side of my parked car at work? (stupid insurance company rejected the claim because of a previousy unrepaired minor dent by the sideview mirror)

 

Daniel, you do some amazing work on writing instruments with dents. Hats off to you!

But that brings up a question I had after looking at your before/after repairs Daniel. For most of them I can imagine techniques you might employ to remove the ding - some perhaps similar to auto body techniques of chasing or hammering out the distortion. The one that totally stumped me was #6 - you know, the round punch like mark that appeared fairly deep. In that instance, the distortion to the metal had to exceed elastic limits, resulting in permanent material displacement. Only solution I could see was filling some way. C'mon, you gotta take me outta my dilemna. Fess up - you did use some filling type repair - right???? (It was a beautiful result regardless)

Did you mean the one labelled "Another Parker 51 Heritage Cap"--the 7th one down the list? (maybe Daniel added a few pics recently and the pics are now in a different order....)

 

Amazing repair :blink: ....

Yes, that dent represented plastic deformation. But why do you assume that plastic deformation is one-way? Admittedly, shrinking is rather trickier than stretching, but not impossible.

 

I never use any fillers when reversing dents. That's why I call it 'reversal'...

That's right folks. It isn't a big secret that most metal sections of pens are deep drawn. That is why in some metal barrels no joints can be seen. These parts are formed from sheetmetal of high ductility. To illustrate this point imagine a metal box being pressed out. If you can imagine that the metal has a certain thickness. On the external of the folding edge is where the metal has stretched. Whereas, on the internal of the box in the same edge, deformation in the form of compression has taken place. Daniel would need custom made tools for doing what he did. What he did is indeed the "reversal" of deep drawing. In order to execute this reversal process to a finish as displayed by his example requires extraordinary high skill in addition to the special tooling he uses. Did I describe this right Daniel?

Don't forget the magical incantations and the sacrifices to the God of Smooth Surfaces (the patron saint of quality footwear was no help).
