When the conduit was installed in the mast of my 38, we used long sections of
thin wall PVC electrical conduit. The mast was down and laid with the front of
the mast on the bottom, then the spreaders were blocked up to make the front
curve of the mast the lowest point on the interior.

If you lubricate the threads, reduce the torque by 10%. The torque
values on the list (which I generated decades ago) are based on dry
threads. They calculate a little high on the nebulous yield strengths
of stainless steels. Be careful going on the high side.

Josh and Rob - thanks for your comments. I did torque the bolts while in
the water after reading a convincing post about how little extra torque is
needed to overcome the weight of the keel (think of the leverage of each
bolt's screw thread). The suggestion for a much heavier keel only worked
out
Hi Chris & Josh,
I am not in agreement that keel bolts can only be
tightened while the boat is ashore.
While that is a convenient activity during the
annual haulout period that Eastern boats get, it
is not entirely practical for us on the West
Coast or the lads down south. We might only
Hi Josh,I highly respect your opinion, but on this one I have to differ. Rob
Ball, the designer of many of our boats, dispelled this a number of months
back. If you think about it, the actual amount of weight held by each bolt is
actually quite small in comparison to the compression forces
Josh,
If Chris rebuilt the mast step, he must have unstepped the
mast..don't know how one could rebuild it without the mast out.

Chris,
The prevailing wisdom of this list suggests that the keel bolts only be
torqued while the boat is resting on its keel, generally about 60% of it's
weight depending on the design. In this way you are not turning the nuts
against the weight of the keel or even trying to compress the bedding
