During several decades I have looked for a device that hold the work-piece steady when working on the worktable. Something like the equipment they hang wings and doors on in the painters shop. Smaller parts, for example wings or valances, have a tendency to float around at the table during the work. Usually much of the work is wasted to hold it.
A few years ago I saw the solution on the problem in a film at Youtube made by Lazze. Thank you Lazze for the idea! After some thinking a similar fixture, with several important further developments, was made in the workshop, Image 1.
The frame is made of 40x40x2 and 45x45x2mm square tubes. The small one slide through the bigger without too much play and they are locked to each by M8 screws.
Since that day I can concentrate on the work with the repair object hold rock solid. The key detail, the articulated and lockable joint in Image 2, is very detailed described with measures in the book.
I really recommend this or a similar fixture to everyone with this kind or problem. It is like having an extra man or employee in the workshop fulfilling its duty without complains and salary.
An important detail is that the fixture is fully adjustable in all directions, X, Y and Z, see the book. And it is easily dismantled within a few minutes and all parts can be stored in a corner of the workshop.
Images 3-5 shows a small, a medium sized and a large part clamped in the device and Image 6 show how two arms are fitted to the worktable for holding a MG TC front wing to the table during the repair.
An important development is the door holding kit in Image 7. The door can be rotated for access to both sides of the door.
Maybe the fixture not is a solution for the average DIY enthusiast but for those who more frequently meet the problem it offer a good solution.
Often aftermarket parts have an inferior quality, many times the manufacturer have simplify the part. The Chevrolet Camaro wing repair part in Image 8 is an example of that. The pressing of the lower edge was completely wrong or absent. In front of the part is a new lower edge with correct shape made in the workshop with a simple press tool and pressed exactly like the original wing.
Image 9 show the tool made from flat steel of different dimensions. Note that the removable pin and end piece make the tool able to use as right and left handed. When making tools like this it´s important to plan the process in small steps and work in a correct order, see the chapter dedicated to press work in the book. With creative thinking and increased experience and an experimental mind it´s possible to make very advanced details this way.
The pressing was made in a workshop press, it could also be done in a heavy bench vise. In Image 10 the new part is welded to the after-market part. In next step the repair panel and the wing is joined.
