sail cam roller seizure
I have a speed sail where a roller on one of the inaccessible cams above the boom has seized onto its spindle and won't spin after much salt water use without fresh water flushing. It can be reached by putting hand and arm up the luff tube but I can find nothing to grip it with once reached. I've dripped in a penetrating oil using a syringe through the luff tube and then left to penetrate but still the roller is rock solid. I know from unseizing quiver bag zips that salt residues can form an unbelievably strong 'cement'. Any suggestions on how to free the roller would be gratefully recieved. Many thanks.
I'd try some hot water.
Connect a garden hose to a hot water spigot somewhere (often found in a laundy room to feed hot water to a clothes washing machine) and get some sort of fine nozzle on the end of the hose (find one of the little brass ones that looks like a miniature fire hose nozzle) and then stick the hose up the luff sleeve from the camber access below.
Turn the hose on (not real hard) and direct the stream of hot water at the sticking camber roller. Try to hit the end of the roller so the water tries to flow into the "bearing
area" around the spindle the roller turns on.
I would "drape" the sail over saw horses or something so the area you are working on is lower than the rest of the sail.
I do not think that hot water that you can stick your hand in would soften the glue seams in your sail, but I would avoid getting the hot water on the seams, just in case.
Hot water has "unstuck" alot of zippers that penetrating oil didn't budge, in my experience.
Hot water melts salt deposits more quickly than anything that I know of.
Also, do the SS spindles that are the "axles" for your cam rollers come out of the cam?
Might be good to just pry the whole assembly out, unstick or replace the spindle and roller, then snap it back into place.
Hope this helps,
What brand/type of sail is it ?
I'm surpised that you cannot get the camber out of the sleeve.
I thought they all detached from the batten holder ?
Another possibility is to get a sailmaker to open the sleeve where necessary and then
install a zip after you have fixed the camber.
Thanks Roger and unregistered,
Hot water sounds good, will try this. Opening the sail is a last resort but as you say could close with a zip.
