Hi All
Just after some information, I have to replace the halyard sleeves, so I was hoping someone will know the sheave and pin sizes as
I really don't want to climb the mast twice if I can avoid it.
A bit like asking how long a piece of string is. You really couldn't know for sure as they may have been replaced before and drilled out for bigger pins or different sheaves fitted.
The other thing is if you are doing sheaves and pins, how are you going to get up there safely??
I think it is a job that should be done with the mast down. A lot less stress and you can do a recondition of the whole mast head and know that everything will be right for another 30 years. 
Yeah +1 on taking the mast(s) down to do the job.
Most clubs should have a crane big enough to pull a H28 masts out, just get a nice long lifting sling to keep the hook clear of the top of the mast.
Hi there, and welcome to the forum.
There is a few of us here with an interest in the Walker H28, so please tell us a bit about your boat. Where are you based, history of the boat, problems, mods, etc.
Hi walker my masts are in storage while im renovating
I have to ring the rigger today so ill ask the question
In swapping out mine i think as there originally
Wire halyards
I am changing to rope 8 mm i think
Ill ring a couple of owners and post latter
Thanks for following up on this info, She is currently called Malolo I will be changing the name to something easier to use for radio transmissions (with a suitable ceremony to satisfy Neptune), previous to that she was called Magnum III., based in Port Stephens and Sydney
I bought her about a year ago as a very original but neglected vessel, as pre-retirement project, with the aim of doing some east coast cruising when retired. Unfortunately since I brought her I have doing constant traveling with work so I have been neglecting her too.
Looking to slip her in the next few weeks so want do the halyard sheaves (currently wire halyards) as part of a long list of jobs. Currently moored in Croudace Bay Lake Macquarie.
As for using a club crane or some other structure to drop the mast very limited options in Lake Mac, I have done it a long time ago but too many issues now (insurance etc).
My mate got his mast taken out at a local marina and was charged a daily storage rate for the mast as well as having his boat on the hard!!!
I could not find the sheath or shaft size sorry about that from memory when I removed the mast Id say it was around half inch but that's not good enough to stop you climbing the mast twice I'm afraid.
My masts are not close to the boat or home presently
I will be ringing the rigger tomorrow maybe there close and he might measure them for my
Hi Walker 28. I nearly bought your boat last year as I am in the same position as you- pre retirement. Unfortunately like you, I have not managed to retire yet. I was not game to sail her to Sydney without doing a lot of work on her, and Port Stephens was just too far away to commute for weekends.
Did you replace the motor kill solenoid on the engine? I had to stop it using the de-compression lever, and that is not good to do too often.

There is a very good mast crane at LMYC but you would have to check up on conditions of use etc. Also once you have it down you need to take it somewhere to work on it. It may be possible in the club hardstand area.
Hi Yarra
The stop solenoid is on list when I slip, I only replaced the radio before I sailed her to Newcastle then Lake Macquarie, although I waited for good conditions to do these hops between work commitments. She sailed beautifully off shore with nice easy motion.
Cisco, will investigate the LMYC, a work colleague is a member so may be able to get access though him.

you can always crack the injectors open . When I first looked at my old boat and powered her up I didn't realize the solenoid needed the ignition on to shut her down .
so I cracked her injectors open to shut her down
'The Bukh's like to have the system so in a life boat the motor will run with out any power once it starts it cant be stopped with out 12 volt power
you should buy that one up North Yara and get Cisco to sail it down for you
Thanks HG the photos are a great help, I will be sourcing the Ronstan RF40000HL sheaves that should do the job
www.ronstan.com.au/marine5/product.asp?ProdNo=RF40000HL
I am slipping the boat on the hard next week, the marina won't let me climb the mast on their property so I'll have to do the replacement later, will let you how it goes.
Thanks again
