    For my Tech write up I decided to show how I have been trying to make a model a quarter panel. This is my first tech write up so don’t go to hard on me. I didn’t finish it but you get the idea. So I started with standard piece of Sheet metal. The first thing I had to do was measure 5 and ¼ inches down, this is where I would roll the bead, the bead is put there as the bottom of the belt line. Using my Poor quality Beadroller it takes quite a while to do as I dont have a sweet power roller like the Baileigh one ;)

    Next I cut out the panel about 30 inches total so that I have some room to spare. I measure 21 inches from the bottom of the belt line and put a break in the panel.
    Using my jig that I made for the bottom roll I flip the panel upside down and tighten the Jig down so that I can create the bottom roll. I roll it up by hand moving a few inches at a time. I then measure and put a break in the roll to match the factory qt panel.

    Once I have created the bottom of the qt panel finished I move up to the top and finish my two other bends the first being 2 and 1/2 inches from the belt line and the second being 1 and 1/4 inches from the last bend

    Now I have the overall look of the qt panel. Next I cut out two pieces of sheet metal that I traced to have the same contours as the panel. [​IMG]<br>[​IMG]<br>[​IMG]
    I then use my Poor quality Shrinker/Stretcher (Sure could use a Baileigh Shrinker Stretcher that would help out quite a bit) To make the contour match the old qt panel. I do that twice the second side I do it with a piece that I put in two breaks so that can flush fit my doors but without the breaks I would have a stock qt panel. I then Tack the ends in place. Where I will later finish welding and cut and trim any left over areas. [​IMG]<br>[​IMG]<br>[​IMG]<br>[​IMG]<br>[​IMG]

    My quarter panel has been extended to 15 inches so to make up for the extended cab that my grandfather wanted. Here is the finished product and it next to a reproduction qt that i put an extension on.

    Now I just need to repeat the step one more time for the other quarter and then make two new door skins. which if anyone wants to see I will write up a tech article when I do.
    Please let me know if you have any questions comments or want any other photos or measure ments.

    I will definetly do that when I get around to making them, my hope is that I win the contest :rolleyes: (high hopes) so I can show the difference between the tools I was using and a baileigh tool.

    Great tech. Shows that a lot can be done with a little. A little skill, a little patience, a little encouragement and a little bit of equipment.

    Just curious, how much time is in the panel? How much in the fixtures?

    I spent about 2-3 hours on the qt panel and that included making the jig... but that was my 5th attempt or so at making them to finally get it the way i liked it....
