I have 3 Grandsons under the age of 3 and one more on the way in about a month. My thought is to make paddles that they can use when they come out to visit. The Old Town paddle in the picture is what I would like to make a down sized version of. So if I do half scale size would it make sense to half size the shaft diameter too or would that make it to fragile? I want them to be able to use them without worry of them braking easily. Is half size the scale I want to go to? Any thoughts, comments or dimensions would be most appreciated.
