March 2015.....

The International One Metre series is the most popular and simple of the racing model yachts. A good place for the beginner sailor to start. I doubt that I will get into serious racing but this will be a good model to learn with and will be legal should I decide to take it more seriously. The plan i amusing is the "Emo".....a design by Frank russell.

The first step is to cut out the "shadows" (temporary bulkheads) from 1/8" ply and affix them all to a rigid board at the proper spacing.....there are eleven of them. The 1/8" balsa planks are then cut with a balsa stripper and laid over the shadows fitting as accurately as possible.

The balsa planks are cut with a bevel on both sides using a balsa stripper with a 1/4" shim on one side, this gives more gluing surface and makes it easier to align the planks.

Here the fibreglass is going on, one layer of  2-1/2 oz. cloth and one layer of 3/4oz. on the outer surface. There is another single layer of 2-1/2 oz. on the inside as well. Z-Poxy Surfacing resin is being used here......it is designed for lay-up on a balsa surface. It is now broken out of the building formers and weighs 315 grams at this point......very rigid too!!

The vertical keel and the rudder are cut from 1/4" balsa. The keel is covered with unilateral carbon fibre and vacume-bagged for a tight adhesion to the balsa. The rudder is covered with 2 1/2oz. glasscloth. both will be painted with a high-solids primer and sanded before final paint. The second photo shows the use of a lazer level to mount the keel and rudder accurately in relationship to the water line.

Here is the keel box and the finished keel.....the keel is pulled into the box tightly by the attaching bolt  and it can be easily removed for measurement by the race committee..The lead bulb was hand shaped from a rough lead casting. The whole keel and bulb weighs 2495g. at this point.

Here is the layout of the arm servo and the sheeting lines that I am using.....This is all installed before the decking is laid. The upper picture shows the hauled-in position and the lower shows the full-out position of the sails.

                                 Here the decking is on and primed and ready to paint.
