    Diving right in and tackling the hard projects. If one does not try, one will never know how it's done. Kudos to you and your design team.

    Hi!
    I do translate works for this forum. But now I have no time for it because there're lots works at ZIM and I have some tasks from my university.

    New updates'll be soon. And it'll be very huge and interesting!

    Hello!

    Well, the long-awaited moment came. The moment when I could start large-scale metal forming. This post is focused on the manufacture of the rear wings for Zim.

    As usual, it all started with the workpiece. But the master model has volume and even careful measurements of linear dimensions do not guarantee the accuracy of the pattern. The solution is simple. I made a pattern out of cardboard. I fixed a thin sheet on a grid by binding wire and attach the plate to the least relief portion master model. Then, bending the blank template for future grid shape, I fixed the place in which it is folded. Subsequently, these folds are cut, just like a tailor makes the manufacture of darts on clothes. When all the cuts are made, and cardboard repeats volume of the grid, its shape can be transferred to the metal. Making a pattern of metal marker I transferred all the cutouts on the workpiece. They show me what places and how stretch metal to get the desired shape.

    Now the work begins directly with the metal. First of all, I shrinked the edge of the metal as much as possible, focusing on the most amplitude places. Then I rolled the main wing area by the English wheel until the desired curvature of the surface was got. Wing is very dimensional, so we worked together with apprentices. English wheel also can't give the necessary form, so in some places I have to work with a mallet. In the molding process, I constantly checked with the master model.

    After few days "wing" becomes similar to the wing. But in some places there is excessive convexity of the surface. One way out - to warm up the metal around the edges to soften it, and upsetting unwanted bulges burner by straightening and subsequent quenching. Warmed metal can be shrinked again.

    When the shape matches the shape of the wing master model, I could proceed to the final straightening. This can be done only after the installation of the wing into place when all edges are fixed and the item retains its geometry. I'll have to postpone this step at a later time, as not all constructions are mounted on the body.

    The next stage - making layouts glasses through which I'll can more accurately determine the location and geometry of the longitudinal arcs of the roof.

    So, to be continued!

    Hello again from breezy Russia!

    Now I'm going to tell you about making tailgate.

    First, I defined the necessary dimensions of the workpiece and cut out the pattern of aluminum sheet 1.5 mm. Then I spaced blank, painted on it longitudinal and transverse lines in areas corresponding to the position of reference profiles on the master model.Then I started to roll the sheet along the center line, gradually shifting from the center, forcing him to bend sideways. I roll model in longitudinal and transverse directions, constantly referring back to the master model and the increased frequency and intensity in those places where the sheet should have the greatest convexity.

    As well as English wheel I used shrinker to gather the edges and increase the bulge. Proceeding shrinker and English wheel, I walked up to the desired form of a sheet. As a result of the rolling sheet slightly increased in size, and I cut the perimeter about 20 mm. As a result, I need to remove from the surface traces of shrinker's jaws, and a couple of small bumps and pits where they were not needed. The result, I must admit, was very pleased, and although from the beginning I had no doubt of success, yet I was impressed by the item.

    Wow, you, Sir, are obviously a master!
    Making those large forms in just 1 sheet= immense skill!

    And the forms are also beautiful!
