Text in the Assembly Manual & New Kayak Shop warn plans builders about the necessity to make quite sure that the two bottom and the two side panel sets are a mirror-image of each other.
In other words, make absolutely sure that they are identical. This stands to reason. However, by the time one has block-planed the clamped panels down to the pencil lines, and repeatedly run one's fingers along the edges, little doubts start to creep in !
Is this a slight "step" or not ? So one touches up ever so lightly with a freshly sharpened plane. Another run of the fingers down the panel edges ..... In the end one decides enough is enough as the imagination starts to play tricks.
My question: Just HOW crucial is PERFECTION ? I reckon I've got the tolerances down to less than 0.2 of a millimetre (maybe even 0.1). I'm now itching to start drilling the holes for the wiring, then doubt creeps back ....
Any one had similar doubts ? Does your little boat go around in circles when you paddle it ?
