Wet forming: how much curvature is too much?

Ah..lots of thin layers each molded to that complete shape..could work, but they'd all have the same outside and inside dimensions, so how would you Matryoshka* ( матрёшка ) "Russian doll" them into each other to glue them up ?

* yes I know..verbing nouns weirds them

@mikesc Perhaps working "inside out" would work? That is, start with the first layer, and then shape the next layer on the wooden shape with the first layer of leather on it. However, I suspect you would need to come up with a "variable size outer mould" to adapt to the extra layers.

Edit: Ah, I see toxo already replied.

Anyway, if anyone has some bull scrotum they have for sale - let me know

Yep..I was still testing stuff on that laser ( other concurrent thread ) and missed Toxo's and your replies..Hadn't thought either of you meant leaving on the layers and building over the top of each..That would work.

Since it's hard to get proper rawhide in small quantities quickly where I stay, I used one of those dog-chews for rawhide (which is just very thin low quality split side). And the thin leather did conform to the shape, but with many overlapping folds on the side. I also improved my leather press a bit, and managed to form the initial veg-tan a bit further, which gives me hope. I think I need to make a new form which changes more gradually and looks more like a bell, as someone mentioned at the start of this topic.
