Miles and miles it has.
That doesn't mean you can't lose them still. But I keep mine in the shallows where I can see it. Once you can't see them anymore it's scary.
When I started the work that had been started over 25 years ago by it's original owner looked like this. I worked the 3 day weekend to correct all the warps and mis-alignments.
Much better. Now I have to fix and drill out all the limber holes next. The ones he made are so off I made a tool to correct them and make sure all the rest are the same.
Tool goes into some Evercoat metal glaze putty and is removed.
