EW for shaping 6mm aluminum plate
I just found this YouTube video interesting in how they formed the curves for a boat hull using english wheeling techniques. 6mm plate and the physical size of the panels and only one person doing. I will leave it to the experts to comment more. In my 30+ years of using an EW (all automotive), I never envisioned something of this scope and figured a few of you might find it interesting.

Yes, that's a serious English wheel. Great to see it operating. Thanks for posting.

Very cool.
But, given the male/female roller die set being used, this machine is imparting shape into the metal more like a bead roller than an English wheel. If it was acting like a proper English wheel simply applying pressure alone between a crowned anvil and a flat wheel, I would think it would take a lot more effort to make the same shape in 6MM material..

Mark,
Thanks for posting that video as it's good to see the whole operation going on and the end product, will have to wait for the next update video. Years ago I ran across some images on a UK website of that being done, again for a sailing boat, and more recently the same on an Australian website but they were just still images not video. It would seem therefore that there are more large heavy duty EWs about than one might imagine. The Australian site http://www.radford-yacht.com/wheel/wheel.html

Good to see the posts of yacht/boat hull builders mooshing those big ole thick panels.
Giant wheels are the ticket for sure. Like the big thick stainless "Chicago Bean" it takes time, planning and careful accuracy. (saw one giant wheel up in Pacific NW years back, using Low and Reverse gears in a 4spd truck trans. to push-pull the 5ft x 12 ft trolley panel-carrier forth and back through the rolls, making hull plates. Cool stuff. Real "full scale" panel work, for certain.

I remember a while ago seeing steel plate for a large ship being wheeled but it was done vertically.

Marcus,
Re vertical wheeling. Did the wheel traverse the sheet or vice-versa? Were they conserving floor space?

check out these videos for even more impressive hull plate shaping work! makes that 6mm aluminum look like a cake walk
https://www.youtube.com/watch?v=hn_Jqp9gXBo second video is particularly fascinating as it shows the shaping of a saddle (reverse curve). The roller press appears to be a "true" English wheel configuration where the rollers are flat, or ever so slightly convex. Massive pressures used https://www.youtube.com/watch?v=Xuo2XwfqV0o
