G'day,
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Visionarry mast below is also out of date due to recent increases in carbon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.
Regards,
Rob

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materials list are out of date badly, so I'm just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.
Thanks
David

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