After months of fettling i have a complete bike again, only issue now is one gear selection, the third one down starting from the biggest on the rear cassette jumps and the chain will not engage with the teeth.

under load its worse.

i suspect a new cassette is the answer, but am hoping there is a cheaper solution, hey its worth a try.

    what are the parts? (part numbers). shifters and cassette.

    is the mech hanger straight?

    All good questions, no idea, shimano stuff basically, hanger straight and rear derailiar stripped cleaned and is ok and working.

    chain only skips in one gear, always on the same cog, rest of gears index and run fine.

    If its a cheaper SRAM, there are sometimes the individual sprockets being sold on ebay, so you can change the one gear cheeply (if yours is the dismantle-able type!)

    Start here. http://techdocs.shimano.com/techdocs/index.jsp You should be able to order single cassette cogs but you need to know what model drivetrain (Sora, 105, Ultegra, Deore, etc.) usually labeled on the rear mech and some of the other parts. The blowup diagrams will give you part numbers which you can order from most LBS's and some online stores. Measure your chain first to see if it actually needs replacing as it may just be the cog that's worn.

    Salt + water is a cheap solution

    Sugar plus water being cheaper still...........of course plain tap water is a (weak) solution anyway!
