Job List for 22 August

We’ve had a trial fit of the building frame on the caterpillar. The good news is that everything goes together very nicely. This means that we’re at the end of phase one of our build and can move on to setting everything up for serious boat-building.

General Clean-up

We should now have our first big clean-up of the building space, as we’ve finished making our kit of parts for the main hull and won’t have to make any new pieces for the next month.

We should gather up all scrap plywood, saving the bigger bits of marine ply and scrapping the cheaper stuff that the moulds were made from.

Finish the Frames

The four frame pieces have all now cured and can be unclamped.

The inside faces and the flat fronts and backs will all be visible inside the completed boat, so will need to be sanded to remove the runs of epoxy that have squeezed out. The sharp edges should be nicely radiused.

Finish the Building Moulds

The mould pieces are all looking good and need to be cleated together using fish-plates made from scrap ply on both sides of the upper sections and the cross-spalls from CLS timber, which Ray has been making.

The online instructions for the set-up are available here:-

We’ll have a few paper copies in the shed for reference as the evening proceeds.

The instructions are very clear and easy to follow, so I won’t try to improve on them. They are written with the traditional building ladder set-up in mind, but I don’t think any changes are needed for our closed caterpillar set-up.

Note that Mould 1, at the bow end, will be screwed onto the outside face of the wee open two foot box furthest from the door. It’s been left clamped in position.

Note also that the cross-spalls go on the AFT faces of moulds 2 to 5 inclusive and the FORWARD faces of moulds 6 to 10 inclusive. This is essential to ensure that everything can be taken apart once the planking is complete.

By contrast the frames will go on the FORWARD faces of moulds 2 and 4 and the AFT faces of moulds 6 and 8. This is so the edges can be bevelled slightly to give a close fit to the planks.

There is a box of long screws to secure the cross-spalls to the top of the caterpillar, one screw on each side of each mould.
