Re: It\'s a flippin rachet!

It seems a trivial thing to say but I've managed to unseize sheaves in deck organisers by gripping them hard with water pump pliars and trying to wiggle them back and forth. Eventually you get just a bit of movement which increases until the thing is free. Needless to say douse with penetrating oil first. In the case of your ratchet, can you lever a stout screwdriver underneath it to give an upward lift followed by a light hammer blow downward? Keep on doing this in alternate directions until you get movement [hopefully]. The main message is to persist despite the lack of any initial movement.

I believe that it's not advisable to use a mineral oil (WD4*) or any synthetic engine-type oil on nylon, delrin, or brown (resin-based) Tufnol sheeves. It is not uncommon for them to absorb oil and then seize up, as well as trapping any grit and converting it to a fine grinding paste. Candle wax seems to work well, but it does need the block in pieces to apply it.

My deck organiser sheaves are aluminium running on stainless steel spindles so I think that they need some barrier of lubricant between the dissimilar metals.
