Turnover Part 1 – planning

As with the rest of the build, I spent a while planning exactly how the boat would be turned over. In his notes that accompany the plans, Iain Oughtred suggested that the lead keel ‘may’ be attached before turnover, but that this will ‘make the turnover more interesting’. This wonderful piece of understatement certainly rang true, and resulted in a spectacular piece of over-engineering on my part. With nearly half a ton of lead fixed to the bottom, I certainly didn’t want the turn to become too interesting, and besides, there was not enough space to let the boat roll over across the room, however strong we were feeling, so it had to happen with the boat staying in the same area.

The first thing was to build some gantries, with which I could lift the boat clear of the jig (and which also came in useful earlier when doing the keel). I also designed two big wheels to encircle the boat, both to have something to lift it by, and also to provide an easy way to turn it over. The wheels were made in sections so that the lower halves could be attached when the boat was lifted and the building jig removed. Each wheel then sat in a trough, complete with plywood rollers. The gantries and wheels were all made of 15mm spruce ply, and proved extremely satisfactory.

  1. Wow!
    I also have the Haiku plans but the level of detail you have gone to in planning and execution have left me reeling and in awe.
    Keep up the good work!

  2. Thanks Dean. I hope you do your build, and that it goes well – keep us posted!
