This will be added to, to give starting points for reeding Hunter chanters and regs. If you are after something in particular, drop me a line at firstname.lastname@example.org and I will update here for all to see.
I am reluctant to give exact measurements, as what works for my method may well not work for yours. If the reed is out of tune, change a parameter – there are several excellent reed making books out there to help you with this.
Concert chanter. Staple rolled out of 0.5mm copper, 52-54mm long, 14.7 -14.5 – 13.7 where 14.5 is the mid point of the staple. Head width 12.5 – 13mm.
Regulators – 1/8″ internal copper tubing staples for most of these. To make them grip the tuning slide tube, bell out the very bottom of the staple with anything tapered, I use my smallest needle nose pliers (closed). Some of Peter’s flat regs use smaller than 1/8″ internal staples, 3mm or even less.
B and Bb chanters work fine with 1/8″ internal tubing, head width around 10-10.5mm (I go for 10mm for all flat reeds)
C, C# and flat D chanters – I roll staples for these, though Peter didn’t bother. I will update with dimensions when I’m near my notebook.
