These paddles needed lots of modifications. The Aurora bearings also must be installed, and Kerry sent a mail late last night (Norway time) that this will be a very tight fit, possibly moving the hole for the bolt longer out. So I took one bearing just to see how it fitted.
The one and only paddle that was according to plans, looked like it would fit exactly, but the one with the hole filled would have no chance of fitting. So I drilled out the rivet, countersunk also on the other side, and riveted a new one in. Then I filed off the excess and had a nice "foot" with two perfectly flush surfaces.
To be sure the bearing would go clear of the foot, I dremeled the hole a bit oval, then drilled #13 and reamed up to #12 for the AN-3 bolt. In the end I had a hole that was offset enough to give a clearance of about 1 mm (checked with bushing and AN bolt into the bearing). Finally a set of paddles that fits and is according to plans.
