If the 29 is like the 30, then the whole top of the mast (aluminum casting) comes off - it rests on the top of the mast, but the casting goes down inside of the mast. The sheaves are in the top piece, and you must take it off to get the sheave axles out. Mine is secured with about 8 stainless screws, evenly spaced around the casting. It is a tight fit, it took some prying with small pry bars to get it out.
I agree - I think the 29 is keel stepped and if so, keeping the lowers in place and using the pole topping lift can hold the mast in place while you work on the top. But, your crane must hold you up there without any help from halyards and such, as they are all attached to or through the top casting.

On the 35-3, you would not have to affect the standing rigging to change a sheave. It should be possible from a bosun's chair (at the crane or on other halyards). I would suggest going up to check what it looks like before gathering the right tools and planning the job. On the 35-3, the sheaves are rigged similar to those on the boom. There is a stainless cover over one end of the sheave axle. When that is removed, you should be able to push the axle out and remove the sheave (holding it as others suggested). Yours may be different, but it may not be necessary to remove the mast cap.

Can we take off the cap at the mast tower and avoid hauling out the mast for the replacement? _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com ------------------------------------------------------------------------------ _______________________________________________ This List is provided by the C&C Photo Album Email address: CnC-List@cnc-list.com To change your list preferences, including unsubscribing -- go bottom of page at: http://cnc-list.com/mailman/listinfo/cnc-list_cnc-list.com
