Anyone know about this floating egg?

    Maybe, but as I was thinking about it in that long post I couldn't help but wonder if that whole process still left you a lot of minor milestones to help keep you interested and feeling positive, things you could even schedule for. Sure, early on it may take a day to form and fit one long/thin panel, and another to rivet it on, but that means each one is a small achievement in its own right.

    Compare that to FC I mentioned in the last post: which would involve lots of time on the armature, without much to sense of incremental achievement to mark progress, and then a quick plastering hoping all your guys are doing it right. I could see that as rather discouraging which may be why so many such boats took so long to make.

    Ferrocement would be a lot easier but i think a big part of what attracts me to boats like this is their toughness. Built like a tank. Cement on wire turns it from a steel tank into an egg shell in my mind making it much less attractive.

    I still havent entirely ruled out steel but the more i research, the more i realise how inadequate my skills and knowledge are for a project of this size.

    I just tuned into this discussion. This boat was way ahead of it's time. Fast forward to today and what do you see? Euro styled bubble boats that look as if they are pumped so full of air you can't even walk on the foredeck. All to make room on the inside. That's progress! Good luck Pirate. Please post a few pictures of your build if you go through with it.

    Ummm ... forgot THIS tool.

    The planishing hammer: http://youtu.be/sK0oGJEf1Hk

    Here is a tool actually well fit for the kinds of pieces you'd need to make. For your use with larger and longer pieces some sort of feed table, as commonly used in woodworking, with the ability to clamp a piece or just hold it is some stable alignment (tilting table) would greatly facilitate things.

    Some guys have all the best toys!

    Side note: you'll get to use your inner framework for your buck so there's some time saving.

    My two cents is still with chines. How could it be possible to make a football shape easier than this? In two minutes ProSurf makes a football shape AND the plate development. All the plates are perfectly developed so putting it together would be easy as far as fit up goes. I don't think you or the sea would notice the difference of the hendecogonal cross section over circular; add more sides if it doesn't wind your watch tight enough! Forget all the english wheel nonsense, I only mentioned it out of respect for the past.

    Personally, I'd like a flatter topsides but hey, I don't monkey with another persons monkey. This would be a blast to build! If I had the right setup, I'd erect it around a gin-pole, laying the plates around the axis like banana peels - ENDO to ENDO vertical construction!

    A side benny, provided are easy take-off points for bilge keels, which you might enjoy. If it was me, I'd chose a tridecagon cross section, though, just to be safe.

    You could strip build an armature for the beast and cover it with a lot of FRP inside and out. It could be near bulletproof and would not be inclined to rust.

    A boat shaped like that will be a pig but it will float.

    I remember years ago there was an Italian engineer who invented a method of building structures from concrete that was sprayed over an inflated bladder a bit like this shape, and when it set the bladder was deflated, and Voila !

    The newest version of that is a system where, IIRC, mixed dry concrete impregnates some kind of cloth like material, you inflate it and then wet it down till it cures.

    There was one at Peakhurst High.... got demolished a couple of years ago & replaced with a "square" building, I'm sure it was still "good" but no longer suited the need, some did fail though...... Apparently some unusual accoustics in the igloo & some angled "dispersers" built for the inside, never saw them up but saw the tooling for them.

    It did not catch on, the one at Kallangur north of Brisbane was eventually demolished too. I think it was called 'Space City" or somthing similar.

    Interesting. People are always thinking of new ways, I guess most flop and we never hear of them, but occasionally one succeeds.
