So now I have a new problem. Keel bolt #4 is down a deep hole and is constrained to a narrow channel. The immediate thought is to simply use an extension. Problem is that the torque multiplier specifically states to not use an extension... I assume on the output shaft. I also assume that the reason for this is to ensure alignment stays perfect while applying such extreme torque.
So, is it better to brace the handle-less multiplier in the bottom of the hole while using an extension on the 1/2" drive input shaft to apply the required torque? Without a handle I'll shore up the edges of the hull to attempt to prevent excessive point loads and crushing. Or is it better to use a 13" long, 3/4" drive, extension between the socket and the multiplier to get the multiplier above the hole? This would allow using the handle on the multiplier.
