Assembling CEIBA’s Frames – SAILCARGO INC.


Frames are the ribs of the ship,
the timber is locally sourced, it’s all milled here on site. We cut it out on the ship saw and then they’re inspected for any cracks or notches or Dutchman’s. Then we bring it up here and chuck it on blocks, they’re big, heavy, beautiful timbers. Then we start with the floor piece,
which involves cutting out the keel notch and cut the joints we start with the off
section and once we’ve got that levelled and all tightly joined we match the forward section on top and then it’s just drill. We do double-sawn frames, 12 pieces per frame usually, 6 aside. The joints are staggered from one frame to the next,
to optimize strength. It has been been taking us about 2 weeks to put a frame together, we have a really good team at the moment. The shipyards really humming.
We knocked up a frame in 5 days last week, which is quite an achievement. Yeah it felt good Alright, coakses or shear keys are small pieces of timber that we use for the shear stress of the frames and they basically seat into the reference face of the frames. They’re notched in on both sides and they’re put in before we tar it and put the frames together. We drill them first with a giant forstner bit and that creates like a hole, then we chip it out with the chisel, rout that out to the selected depth and basically mirror that on the opposing piece and then go in and check that all the coakses are gonna fit in there. There’s two different types of fasteners,
we are using bolts and tunnels. The tunnels are made out of Tamarindo, which is incredibly durable. Wedge is wedge, like so bang that in, one at each end
and it’s never coming out. The bolts are mainly there to support the frame while we`re raising it and the tunnels that’s just added extra strength. Knees or anchor stock are used to strengthen frames. Basically there’s some big curves in in the ship now as we’re heading towards the midsection. They’re really getting a lot of curve in them and it’s difficult to find grain pieces with the grain running all the way through it which is the most desirable
and we have a few but we can’t get all the pieces with that. So the anchor stock is basically a remedy for a short gain or a lack of the desired curve and it provides strength. Clamps are for clamping – we use them to
hold the timbers in place especially when the pieces are matched and also while we drive the tunnels through to make sure that they’re held together
where they’re meant to be. The joints are bedded with tar.
Tar seals the timbers, keeps the water out. To raise it we drop it, we drag it over and then we raise it. We raise the frame with a couple of lines and a few people pulling on each line. We have backstays and sidestays and that’s pretty much it. Surprising how easy it is. The lewis winch is bad ass, it’s a winch with hooks onto the chainsaw yeah
it’s pretty powerful It drags the frames over, no worries. We fastened the chainsaw to the stage here with a bunch of pulleys and then we can quite easily drag the frame wherever we need it. I think this next frame will be the end of the first cargo hold The frames are nice to work with, you never really know how they’re going
to look when you start. Every frame is different and it’s quite satisfying seeing the curves and the beauty of each frame when it’s done. So to raise a frame we tie one single block on each side of the top of the frame. The rope goes up to the previous frame, on the top and it’s running through a block, goes to a post at the end of the boat on each side
and then it’s going down through a single block and then it’s getting attached to
a block and tackle. The rigging that we have for the
frames is a very good and simple system it works pretty well, you can set it up fast if you find the blocks and the pullies and the ropes What’s happening next?
There has been talks of another framing stage, we’ve got more shipwrights more framers. Hopefully we’re going to speed up the process even more, with two framing stages we should be
able to pump them out. We’re going hard
