    Hi Tony,

    I hadn't set my sights on any particular type, just whatever comes up. However I hadn't (until now) considered making my own. Strange, because I have every possible tool available to man and spent 20 years running a woodworking business!

    What timber did you use and did you design it?

    The section on masts, beginning on p120 is very good, Andrew and in particular the graph on p131. There are several opinions on this, but, to keep it simple, this graph shows mast diameter at the partners for a hollow wooden mast as a product of mast height above the partners and sail area. It states in the text that a solid mast can be 10% less in diameter than a hollow one. 

    Many of us use this graph but subtract 10% from the hollow mast dimensions (and therefore a further 10% if using a solid mast.) This is exactly what I've done and I am completely happy with my self-built solid (well, there's a 5cm square hole up the middle) masts. 

    If you're sourcing a second-hand wood mast, I'd recommend bearing these dimensions in mind. If it's a solid mast, it obviously could and should be planed to a suitable taper to reduce weight aloft. Needless to say, it should be structurally sound.

    It's not clear if you are considering a second-hand wood mast or an aluminium one. Frederik has sourced a second-hand carbon fibre mast from a Freedom rig and that certainly looks to be a good option.

    Thanks Tony, I hadn't considered a hybrid, that's a good idea. I looked online and a 5m length of 152mm x 6mm seems to be £380, bearing in mind I need 10m, that's more than I can really afford.

    I've just bought Practical Junk Rig so I'm working my way through it. Still in the early stages.

    Thanks Graham.

    I realise it wouldn't be ideal. It's just that there seem to be an awful lot of mouldy old masts laying around in boatyards. I'm reluctant to spend loads of money on something only to find out it's not quite spot on.

    The search on these forums is quite good, Andrew. Yes, the topic has been discussed at length.

     The main issue is funds.

    Yes, you're certainly not alone there!

    Graham suggests 200mm dia. at the partners, tapered,  and it'll be approx 10-11 metres tall.

    That certainly sounds about right, for a wooden mast. Aluminium could be smaller in diameter.

    I don't even know where to start looking, obviously straight tubing is easy to get, although expensive.

    Well, not in those lengths, it isn't. You can get up to 6m easily enough. This is why the hybrid mast is quite popular - An aluminium tube with a wooden top mast section. Again, a search on this forum would bring up a load of information.

    Is there any reason why I couldn't use an old hefty yacht mast, trimmed to length, if I could find one? is it an issue of strength when you take away the effects of the rigging?

    No, that should work just fine, assuming it's hefty enough. Have you looked at the mast dimensions outlined in Practical Junk Rig?

    I'm planning to convert my Yachting World 5 Tonner and, thanks to invaluable help from Arne, it looks quite achievable. The main issue is funds.

    I don't have an issue sourcing sailcloth and sewing the sail, it's just the mast that is flummoxing me.

    I did meet a 26ft Eventide in the Whitsunday Islands in Australia, who used a cut-down, massive, oval section from some large yacht, complete with gaping holes where the old fittings used to be for his unstayed junk mast.  It was all wrong, technically, and yet, he had been sailing around with it for several years.  It was untapered, too!  I am not recommending it, though, just reporting the facts.
