Interesting video, thank you for posting. Curious which aluminum alloy and thickness this is, 3003? Would you provide link to prior episode?

The shrinker is not necessary and can be replaced by a stump with a dish. hammer blows are way to aggressive on sharp side of hammer which will damage the metal and the wrinkles if hammered out correctly will shrink it and make the process quicker and easier correcting them by hand will just slow the process down

What gauge metal are you using? Aluminum?

I would like to make a helmet with the top part being this bowl shape, is there any formula to calculate how big the material has to be cut at the start to make a certain size at the end?

Kripto You do need a bit of extra material all around. It depends on how far you want to stretch and shrink the material. I would adwise to look for a sample bowl and make yourself a paper or flexible tape template. Cut in the edges , so you can lay out the template flat on the metal. That is the approximate size. Ad another 2cm all arround and you‘ll do just fine.

The book Shortcuts for Round Layouts will answer your question and any other ? you have on this subject,with examples.

Will this process work with steel?

@jessejohnson159 3 жыл бұрын

Yes, but will take longer to accomplish. And a 'correct' alloy needs to be considered depending on the depth of the bowl.

O que e esse saco de couro e cheio de areia é ?

@kaymackenneth5343 2 жыл бұрын

Na verdade, é um saco de couro cheio de areia. Isso permite que a folha de metal seja bem modelada, pois a areia assume muito bem a forma.

While this works with aluminum...this method is NOT the best process for steel. For example, motorcycle gas tanks. In the case of such tanks, you would form the appropriate 'conical-taper' in a roller, to the desired 'width' of tank, then anneal the sections you need to 'further round' (the leading bulb, and the rear saddle taper area), then work it with the english wheel...trying to pay MUCH attention to 'sheet thinning' as you go, and ROUTINELY annealing, as steel will 'work harden' quickly as you wheel it. Once you form the upper tank body, you drill and TIG weld the filler opening, and trim to size plus 12-mm...as a fuel tank is 2-pieces (upper body, and lower tunnel plate)...you would then TIG the lower plate and upper body together, or use an induction welder (projection wheel-type), to seam weld the two together...pressure testing afterwards. As with most-all motorcycle tanks, they are 1018 CRS steel...which is not THAT 'heat-hardenable' (or tempered), but for some reason, working it to deformation requires annealing frequently to prevent brittleness and eventual cracking in-process.
