Excuse me while I rant. It'll make me feel better and it's cheaper than a psychiatrist. 
Trailer rollers and why they can cause a great deal of physical and emotional distress.
1) Cadmium plated fasteners are not y'er friend. So why would anyone use it on a trailer
that will be used anywhere near salt water? Why I ask you? My abraded knuckles,
bruised arms, strained muscles and shoulders want to know?
2) Cadmium plated roller shafts are not y'er friends either, along with their little buddies, pal nuts.
Do you know what happens when salt water is even in the same time zone as those parts?
I left valued pieces of my dermis on the garage floor, along with varying amounts of blood,
this weekend while rehabilitating an old Continental trailer.
I think rust may be a better adhesive than epoxy.
3) Black rubber rollers should not be installed on a trailer, ever, for any boat that will be used more than once.
They disintegrate under load and are not designed to last.
The middle of the roller has a substantially larger inside diameter than the outside of the shaft,
which means it holds water in contact with the shaft, accelerates corrosion and does not
allow the roller to do what it is intended to do, roll easily. Instead it splits allowing more water
and oxygen to make contact with the shaft causing even more corrosion.
The only rollers that should ever be used are the gold polyurethanes with the stainless steel cores
and stainless steel shafts which will actually support the keel and roll as intended,
making launch and retrieval of a hull so much less stressful.
On the bright side, the trailer rehab is done.
My only worry now is how long it'll take before I'm healed up enough to go fishing?
