The prices of some of the stuff (timber and glass in particular) are way down on current prices, glass and epoxy has not changed much in the last few years.  It should be noted that the price for the Visionarry mast below is also out of date due to recent increases in carbon costs.  The carbon shortage is expected to continue until at least the end of the year, which is what they were saying last year.  Expect prices to plummet if/when Chinese carbon plants start operating.
A Harry mast is about half the weight so as a ball park number you could assume half the cost.  Painting will be about the same, as will bonding on fittings and track, although there is a few metres less track.  Say $8,000 as a ball park number, depending on carbon price and availability.

Hey Rob, can you extrapolate (interpolate?) this price for the smaller Harry
mast. I won't sue you if you're out, but I think the figures in the Harrigami
materials list are out of date badly, so I'm just looking for a guide.

Did you make your own carbon rcb track or attach one that can be bought?
