Anyone got experience of repair to the top end of tapered alloy stanchions that have been damaged by wire chafing the internal surface.I am proposing to cut off the worn top, thread the remaing long bit, turn up a new top, drill and tap this and refix to stanchion. Does this compromise the integrity or go against class rules. Also anyone got a storm jib surplus to requirements.
Regards

I believe John Boyce had a similar problem on 'A Sharp Exit' and solved it a different way from you - I'll try to persuade him to post something up on the bulletin board.

I have had similar problems with my Sonata stanchions wearing because of wire chafing.
I considered 4 possible solutions to the problem.
1) Buy new ones. Good idea ?
2) Swap the port with the starboard
stanchions so that the wire then rubs on
the other side. Not a good idea x
3) Rebore the worn hole and fillet weld an
ally plug into place. You could then re
drill back to the original size. It will
depend on how worn the hole is as to this
methods success. Also you will need
to recrimp new wires and ferrels.
Possibility ?
4) My solution was to rebore the worn
hole as big as possible except for the
last bit of wear.I made a special bush
from an old stainless steel bolt, to a
light press fit into the new hole. The
corners of the bush bore were rounded off
on the ends to protect the new wire.
finally the new stanchion top installation
was treated to several wraps of self
amalgamating tape just in case the bush
worked loose but above all for crew
comfort.
Whist in the process I took the
opportunity to modify the life lines to
include webbing for the helmsmans back
rest, which is really comfortable.

Your proposed method sounds like a solid
idea but a bit more work. Please let us
know how you get on.

Good Luck

Providing that the holes in the stanchions are not worn to the point of rendering failure likely the following has been found to be succesful over many years.
1 Take a piece of nylon tubing of suitable diameter & slit it lengthwise
2 Lubricate with brake fluid, open so wire goes inside & ease into hole in stanchion so at least 15mm shows each side of stanchion.
3 Bind exposed tube with self amalgamating tape to retain.

Repair time 5 minutes without dismantling anything & the tube usually lasts 2 seasons

Thanks gents, I have solved the problem by sleeving the holes with alloy tubing and infilling the worn part with a grp paste, the stancions were not as badly worn as we first thought. We finished the job in the Bruce
Walker mode. Plastic sleeve and self amalgamating tape . Thanks to all who called in.
