Metal Shaping for Beginners: Stretching and Shrinking Sheet Metal
This episode adds another detail. With the wireform you can see where you need to stretch and shrink so that the sheet metal panel fits correctly to the buck. You can also use a proto flexible shape pattern like Wray is using in the episode and it helps visualize just how much more needs to be done to get that fit correct. He uses the gathering tool to shrink the edges of the metal but also stretches deeper inside the panel using a beater bag and mallet to add the correct area value. If there is anything that you may have missed that you would like us to go into more detail on, please let us know in the comments below!

    Hi Wray, Hi Mark, thanks so much for these videos, really great stuff. I’ve been following since the mini Jaguar fender, and think that out of the best metal shapers online you are the most innovative (area/arrangement, flexible shape patterns, internal shrinking, facilitators and gatherers ... to name a few concepts where you really change the game). This week I tried making my own proto flexible shape pattern over a wire buck the same way you would make a full surface shape pattern using low tack tape and no stretch tape. Following the buck in the direction of least curvature made a kind of ruled surface; which has one advantage in that you are less likely to over develop the shape in the early stages because the proto shape pattern surface is actually less than the desired end result. It worked almost as well as the full surface shape pattern (which is unparalleled in my opinion). It would take more time than using Tyvek, but is another option I thought you might like. Cheers

    Wray thank you so much for showing the process to develop the panels and the different ways to go about shaping metal. Appreciate You taking the time to share your experience and knowledge. You have given me confidence to attempt to shape some panels for my old truck. I'm going to keep working at it and will get some of the tools built you are using. Do you have dimensions for the depth of the hole in the shaper built from 2x10's and covered in the EPDM roofing? It looks like you have several of them in different sizes?

    I would have had faster results if I had made that Tyvek flexible shape pattern at the beginning. That said I have three hours so far in this panel. With 2 more panels needed to make this complete fender. I stated earlier start to finish for a whole fender is a 30 -50 hour job depending on the tools you use and your skill sets.

    Another excellent video! I love watching an artist at work. As you said before, it's workout, but what you do is not something you can brutalize your way though. When Michelangelo was asked how he was able sculpt the David, he replied it was easy. I just see the statue in the marble and I simply remove what I don't need. As I said before, I'm a woodworker so this the second video of yours I'm watching. The concept or shrinking metal always seemed to me to be like the old woodworker's joke, don't worry if you cut it short we'll just put through the board stretcher. I understand the ductile nature of metal, so shrinking metal is rather like kneading the dough back together laterally. This raises the question, as the larger creases are beaten down to many more smaller creases that become apparently confluent, how does this affect the quality of the metal? Although it's mild steel I imagine it becomes work hardened. Does this make it subject micro fracture later?

    HI Frank, My mantra is "Metal is Clay" just like clay you can do what ever you want with it but you have to follow it's rules. Electrolysis and work hardening are two terms I hear a lot. I see work softening when I work sheet metal, the more I work it the more ductile it becomes. The Italian coachbuilders wrapped aluminum sheet around steel tubes ( 19 mm steel tubing body inner structure) that were probably never even painted and some corrosion did form but the cars are still with us and most were OK. Point is both of those terms are overplayed.

    Wray. I love your videos. I’ve watched nearly all of them. Can I just ask a question unrelated to this video though. Let’s say I Tig weld a long weld in a 1mm thick panel. Say 1200mm long. I hammer (with dolly) the weld to stretch the heat shrinking of the welding. Then I spend a couple or three hrs, planishing the surface of the weld to bring it up, and flatten the panel. Now... after making a first pass, the panel is straight ..ish. But there is still the odd slight distortion either high or low. My question is: at that point in the process, is there a way to tell if the undulation/high/distortion or whatever is due to to much hammer stretching, or if it’s still residual shrunk metal from welding? I have trouble sometimes knowing whether to shrink or stretch. Thankyou for making these videos. A wealth of information.

    Reading the surface is a skill that has to be developed. That said there are a lot of methods to read a surface. The paintless dent repair guys use special lights. I'm thinking of getting one of those lights. My old standby is holding the panel and reading the horizon of the panel as you slowly twist it. You have your sense of touch with your hand, and if you have sweaty hands use a paper towel. Sanding blocks longboard style and I use a six inch diameter Baltic birch 3x8" thick with stickit sandpaper. The body file works petfect too. Lots of ways. If you are high shrink down with one of my shrinking discs. If you are low stretch it up.

    Wray, As I was watching you working on the 'shrinking facilitator' and you got the spontaneous gathers I didn't quite pick up the difference in the hammering method you used to get rid of the spontaneous gathers as opposed to hammering down the shrinks. My take on it was that on the shrinks you hammered the point of the gather first, then the sides of the gather, then the peak being careful not to fold it over. On the spontaneous gathers that you did not want you just hammered the peak down? Thanks for your help, I might learn something yet!

  • @proshaper

    The spontaneous gathers that appear when stretching in the shrinking facilitator can happen where you want them to and where you don't want them to. When they appear in the spot you want them to be you capture them and crush them into themselves, you will see a hard spine of each gather. The other spontaneous gathers you don't capture and crush them you just flatten them out without creating the spine. The spine is proof of the collision of the metal into itself.

    Think of the metal as clay. 12"x 12" x 1/8" thick clay. To make a dome you shrink the edges and stretch the the center. The edges get thicker, the center thins out.

A given radius is always gone touch the same amount of area no mater if the top wheel and the lower anvils are 10 feet wide..... and there is no extra support on the wider wheels theory .... UNLESS the lower anvils are DEAD FLAT, but then , one can not wheel with a dead flat anvil

    Wray explained quite a few times that the wider wheel makes it easier to work with since it diminishes the risk of leaving edge marks on the panel (as the wheel edge is further away from the middle contact point). Just watch his other clips.

    @@tintoycar738 It would seem the opposite is true. In this video and others, Wray explains that the risk with wider wheel is edge bite and we have seen him go to smaller width wheels when working a tighter radius. So why start with such wide wheels if you could only have one English wheel in your shop?
