North East Chapter – Irish Woodturners
The 13th AGM of the Northeast Chapter was first
on the agenda, with the following members being elected to officiate for 2013:-
treated us to an accomplished demonstration in natural edge wet bowl turning. Armed with chainsaw, he sliced
a large ring from a Wild Cherry tree that had recently been acquired. This slice was scrutinized to
determine the most appropriate position to cut out a 10” x 8” bowl blank that would give a balanced natural
The blank was
marked and cut out on the bandsaw.
The centre section of the bark and sap wood was cut away to provide a solid grip
for engaging the drive, and the blank was mounted between centres ensuring that the two high sides and the two
low sides were well balanced.
Turning wet timber takes the edge off cutting tools five times faster than dry
timber, therefore frequent sharpening is essential.
The outside of the bowl was
shaped from base to rim, repositioning the blank if required to ensure a balanced natural
sheer scrape cuts progressing from bottom to top in one pass ensures minimal sanding. Next a basin of warm water was
placed under the turning: sanding was started by dipping 120 grit sandpaper wrapped on a sanding block into the
water and rinsing frequently to clear the grit as sanding progressed. Continue wet sanding going
through the various grits.
Seamus Cassidy with wet turned Wild
chucked the bowl and turned the inside to a wall thickness of 4 mm, ensuring that the chisel is kept sharp
at all times – a blunt chisel requires additional pressure which could cause spigot to break.
Ensure base is similar thickness to walls – otherwise the risk of the base
splitting is greater. Wet sand the inside and trim bark from rim.
It is essential to complete this type of turning as speedily as possible, as
the drying process will rapidly distort the bowl shape. The contrast
between the white sapwood and the darker hardwood gave the finished item that wow

By the way,
watch out for the dreaded woodworm which tend to emerge during March , April and
