#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

Posted by Wassup on 04 February 2007 - 10:06 PM

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 ..

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.

Ya on that type damage I use a sling type pull plate. I use them on truck doors all the time. Next time I use one I'll make a video of it in use.

#359074 Using Tension to Fix Large Dents

Posted by TimC on 16 October 2018 - 07:05 AM

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.

#358995 Sharp Deep Stretched dent repair

Posted by TimC on 26 July 2018 - 09:07 PM

Think of it this way John.  Every push you make (especially with a sharp tip) actually stretch's it but in the opposite direction. When you do that it will pull metal towards your tip from every direction.  When you make a whole bunch of pushes so close that you can barely see that you moved it does the same.  When you do 30/40/50 or however many pushes you make you have actually gathered the metal up in the bottom of that dent and took the stretch out of the larger area.  If you were to make a wrong push outside of the center of the dent you would actually extend the amount of time it would take to fix it because you have pulled metal away from the center and in the opposite direction.  These are very small pushes that he is talking about to where you just start to see the metal moving then move your tip. 

 

I hope that helps.

#358897 How to Remove Crowns in Body Line Dents the Old School Way

Posted by Marty on 03 June 2018 - 11:41 AM

 This video will demonstrate how the old school panel guys rolled crowns (rolled buckles) into body line dents. The glue pulling is a modern touch of course.   Enjoy.

Ya lots of cool shapes you can make with boiling water. I also use my wife oven to anneal aluminum to make stuff for PDR. My wife LOVES IT when I do that!  :)

#358813 Basic Large Dent Repair Theory

Posted by Marty on 10 May 2018 - 09:56 PM

If your talking about the reference to bodyline hinge. That was covered in the class before we did this video so I can see that may need explaining. When a body line gets impacted (say a dent about 6 inches in diameter) the body line, even when it is pushed out will many times still have what old time panel guys called a hinge on either side of the dent as far as an additional 6 inches from the edge of where the original dent was. That means that the total damaged area of a 6 inch body line dent could be as long as 18 inches. 

 

So when you get the original 6 inch bodyline dent out you notice that the body line many times really resists coming out that last little bit. That is usually the body line hinge, 4-6 inches either side of the dent holding the last of the dent in.

 

Now the hinge will not be very visible but it almost always will be a slightly flattened area on this bodyline outside of the damaged area still keeping that last little general low area in the damaged bodyline. So we start about 4-6 inches out from the diameter on either side of where the dent used to be and sharpen the line up all the way into the dent from both sides. When you do this the general low in the bodyline damaged area will easily come up. This explains many times why that soft general low you see in a bodyline after most off has come out, is so hard to push up. It has a long spring on either side of it, hidden in the undamaged bodyline on either side of it, holding it in.

 

This hinge acts like a long spring inside the bodyline on either side of the damaged area holding the rest of the body line from coming out easily.

If necessary I can draw a pic and post it. Kinda hard to describe without a visual aid.
