#359079 Using Tension to Fix Large Dents

As always great video and a lot of good insight Marty. That stand is great. Been looking for a good way to secure a door. Any chance we could get the plans for an instructable? Just the fact that it will hold it vertical and table top is great.

#359074 Using Tension to Fix Large Dents

Nice repair Marty.  This theory is becoming more and more important as the vehicles get thinner and the inner structure lets them move that easy.  It seems like it takes near nothing when a door gets hit to get this type of compression in today's world.  I guess the trade off is that if you had that door skin on an inner structure of a door from 20 years ago, it would have made the outer skin stretch at the impact point.

#341397 08 Saturn View - Dman - Full Demo Article

Posted by TimC on 26 February 2013 - 09:03 AM

I want to add something here about the PPV also.  It was started by Dman not to make money off of the forum but because a bunch of the users of the forum wanted it that way.  They feel that they could share more information among each other if each one made a monetary commitment to belong.  The idea was to keep a casual reader that may not even be a full time PDR tech from seeing the information that was being shared between a lot of really great techs.  That is how it was born for just a little history lesson.  :)

Deep and Irregular Crease Theory.


by Marty Runik


Top Gun PDR Training, Inc



In this article, we will discuss some intermediate, and advanced crease theory. This was a demo dent done for a recent trainee on a hood made with a sharp tap down. A lot of pressure was exerted on the tap down by the trainee in an uneven manner, so there are deeper areas of damage within the crease to make it even more difficult. This is a typical example of a severe crease that is commonly made by a kids bicycle running into a side panel from an angle. See # Fig 1 & 2



Fig #1





Fig #2



Here is a view with overhead lighting to give an idea of the relative size and depth of this crease. See # 2



Fig #3



Pic #3 is a view of the crease with the mini light right over the crease to show the deeper areas within the dent. In many cases this would be close to the proper....

#124446 Cookies, Pimples, Lumpy Potatoes and Pizza

Cookies, Pimples, Lumpy Potatoes, and Pizza. Understand them get rid of them completely.



Pimples are often called other names and some pimples are very sharp because the dent technician pushing the dent out is usually in a hurry and can't fix what mess he or she has created. Pimples are no fun for any dent technician. They take precious time away from what you could be adding to the bill today. Pimples can range from small blunt points to pencil sharp points. There's always a way to fix most pimples although it may result in time and effort. Pimples are sometimes sanded to save time, but if this done incorrectly can result in a smooth spot that actually makes the panel look worked and unprofessional. Remember that orange peel in the paint is our savior; leave it there to help out the finish.

Let's take a dent up and look at the highs we created. Knockdowns can vary in size weight, material and shape. They can also vary in how they are designed. Sharp nylon, pencil point steel bore, and blunt metal knockdowns. The most used knock down is the sharp nylon knockdown. Although times are changing this nylon will most likely be a favorite for a long time to come. Since every tech is different ...

#124443 Avoiding Cornrows

Posted by Marty on 04 February 2007 - 10:00 PM

Avoiding Cornrows


A lot of techs have problems with "corn rows" in their dents. For those that may not be familiar with this term, corn rows are those parallel rows of micro ridges and creases that many techs see as soon as they cross check their dents. The main reason they aren't seen until you cross check, is because light runs right through the micro ridges and valleys when they are perpendicular to your reflective source, because there is little for the light to reflect off of. This makes this area of the dent look fairly uniform, even though it isn't. When you cross check by moving the board 90 degrees, you see the rows because the light is now reflected off the ridges and valleys, the light can no longer run right through them. See illustration #1.





Most often, the tech who gets corn rows is ..

#359282 How to Set Up A Shop for PDR Tension Pulls

I was thinking the same Marty.  Tension works best on panels like door skins where the inner panels give some.  Plus that quarter panel is so short that your only going to get so much pull in with the impact.  I think that while the repair worked he probably spent 10 times longer pulling than was needed since it was conventional and the whole area was bondo anyway.  Some hammer and dolly on the back edge would have worked better than glue and just tapping the edge like he did in the video.

 

Yes you do see the most dramatic results on panels where the inner structure is compressed a bit. But you also see good results on quarter panels and even some fenders and on localized repairs also. Sometimes the damage is very localized but still needs tension to get a fast clean repair.

I would get a dolly up tight in that corner if you can and hammer on the side the bumper attaches.  It would hammer up easier than without the pressure.  I was surprised how much bondo they used.  That told me that they didn't get it as close as they wanted you to believe they did in the video.

There is especially in aluminum doors. Also quarter panel damage when it can be repaired using tension is a huge tome and money saver. You just have to approach the adjuster (or his supervisor LOL) and the customer correctly when selling it.

Marty, do you believe there’s a potential market for offering these repairs to body shops lacking real panel guys?

The plates I use are made from items you can find at any Home Depot store. I use T straps and hurricane straps riveted together. Sometimes just the hurricane straps work.

Yes it's the same principle but this design is simpler. It also stretches in both table and vertical mode which none of the old panel stretchers did.
