Hi, I am pretty sure this question has been covered before, but I
thinking now about casting my lead fin keel.
The architects drawings show the keelbolts bent over inside the keel
to lock them in, but I have always been told to draw a keel bolt every
few years to check their condition.

Any thoughts on this? It would be simple enough to fit a frame with
nuts to screw the keelbolts into before pouring the lead around, so
that they stay unscrewble, but is this the best solution?

And is there a better material to use than stainless steel? - Within
reason that is.

The keel weight is 2 tons
