So,my aluminum halyard winches at the base of my mast is a regular candidate for lubrication. None of the stainless drums require this...just the aluminum.
Am I to understand then, that is not me and my lubrication methods but that these aluminum drums are more prone to gunk build-up? David F.

I used diesel as a solvent any bronze wool as the abrasive. I cleaned all Calypso’s winch innards with diesel (it has a bit of lubricity along with the solvent in case traces are left behind). For grease I use the Lubriplate 130AA, same as for a MAX prop. On the pawls I use a light oil to avoid slowing them down with grease. If racing and not as worried about longevity (“nothing performs like a loaner”), spray the cleaned winch down with LPS or a similar light lube. It will spin fast with low resistance but have very little corrosion protection. I was part of a 1981 Transpac charter of an older IOR boat with gummed up winches (including grinder sized Barients). We cleaned the winches in diesel, sprayed them down with a light spray lube and took off for Hawaii. Winches still worked great when we sailed her back to San Francisco.

There is a lot of corrosion inside the aluminum drum where the bearing rides (went too light on the grease?). Should I use 600 grit sandpaper to smooth it? Other suggestions? I'll be buying the big tub of winch grease this weekend! -- Joel 301 541 8551 _______________________________________________ Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go to the bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
