Bending shapes

[Norm Marentette]

Came across a woodturner in Europe and really like his seashell bowls. Wondering if anyone would have any suggestions on how this process is done? I am thinking he turns a very thin bowl and must either place in boiling water and then shape it perhaps? https://www.benjamin-planitzer.de/en/

It looks like he is turning green wood very thin, so they may just warp that dramatically on their own

Couldn't imagine that's the case based on the somewhat consistent shapes.

I think he must be steaming or boiling and torquing those shell shapes with a band clamp or similar. I have seen descriptions of that being done, not so dramatic though. I like the raw textures he gets with tool marks, carving (apparently) and burning (maybe)- the opposite of polished symmetrical precision.

 

[Alan Weinberg]

pretty cool but his “how I make these” YouTube doesn’t really explain it. He must steam them and use bands as noted above by Kevin. Very talented.

Exactly which ones? Sculpture pieces or bowls?

 

[Richard Coers]

I agree with Keith. Steam or microwave heating, then rolling up with rubber bands or band clamps to hold them to dry.

His lathe is pretty intense....

My opinion is, look up Peter Hromek. Put blank between centers and shape exterior, put a tenon on 1 end to clamp in chuck. Hollow. Think about design on chuck end . Approx 1/4 " thick walls . Remove and cut out side.
I saw him in 2009 aaw in N. M. I altered designs to make opening seed pods .
Old piece..

This should answer your question. Good informational video on how Ronald Kanne does it.

That works for spherical forms, however some of the other guys work is 20×8 .

Thanks for the info everyone! I have seen all of the above videos in my research, just thought maybe he was using something different. I was referring to the sculptured seashells of. course. But very interested in all his work.

 

[Norm Marentette]

I agree with the banding process because of the lip that is consistent all around his pieces.

Looks to me like they've released turned thin and green abd left a knot or limb right near the rim.
