Sanding, Sanding More Sanding

Posted by Paul

Sanding is a horrible job. I think when the designers and engineers design a sanding free boat, everybody will want to build one. Until then the oceans are the domain of the rich or to the dedicated few. My arms are sore, so are my shoulders and my back is just ok. Enough whingeing, I have almost finished sanding the bog layer, I have just a small section of the underwing section as well as the concave chamfer join. I will try the pool noodle idea tomorrow.

After I have finished that last bit of sanding, I will prepare the hull for a coat of resin and a coat of highbuild. I will just give it a clean off. The resin/highbuild coat has to be done on the same day, so I will have to start first thing then wait for the resin to go off enough to apply the highbuild whilst the resin is still green. Then it is back to sanding, again. I will also have a better idea of how well I have faired the hull so far. It is always possible to do a better job but at some point you have to say good enough. One little tip I picked up today after using a finer grade of paper (I have been using the most coarse paper I have 40 grit). The finer paper (I used some 120 grit today) makes for a much smoother finish, but don’t mistake smooth with fair. In fact at this stage it is not important for the finish to be smooth, as the paint will fill all of the sanding scratches anyway. It is ultra important that the job be flat and the chines straight.

I sanded most of the day with the torture board and almost finished the outboard side of the hull with it, but once I had completed sanding all of the above water sections I was getting too tired and sore to continue with the board so I finished the underwater sections on the underwing side of the hull using the flat orbital sander (not the round random orbital). I will have another go with the torture board tomorrow (and the noodle on the chamfer turn).
