Hi Dan,
For a larger cone I would consider making a wooden 'pattern' taken
to a foundry for casting in bronze or aluminium perhaps. Most metals shrink on
cooling so the patterns should be increased slightly: 1/60 (brass and
aluminium) 1/75 (bronze). Pattern makers use special rulers graduated to
allow for this which cause havoc if allowed to 'escape' into a general
workshop. How do I know this??? :-(

Hi Dan, you didn't say how big you were looking for. For small sundials you
can use the cone used for jewelry display to hold rings and bracelets.
They are even available in clear plastic. sasch stephens

Hello all !
Any idea how much a metal cone would cost and where to buy it online? The kind
you can use as gnomon - Ebay has loads of punk spikes on offer, but they are
too small.
Thanks!
