A tape measure.
Sycamore and bubinga.
Rough down the 2 x2 bubinga blank to round. Turn a small spigot to drawing dimension.
Mount the sycamore blank and part of to drawing dimensions. True up the end and form a small dimple in the end. Drill out using a forstner bit, Simon uses a metal depth marker, or use masking tape /marker pen. Simon tidied up the inside then uses some thin superglue to help harden the wood ready for the threads.

Simon turns down a small piece for the cap. Drill a hole for the dowel say 10mm deep. Shape the blackwood sand and buff with oooo steel wool. Assemble ,mark length of dowel and cut 2mm shorter. Mark out for the tape, Simon used a slot saw to cut the small slot. Very cheap but slightly dangerous.
