tongue & groove wood planks make an excellent insulator. I cut planks to
the length required, put 2-3" of water in the pot (in my case making sure the
heating element was covered), brought it to the boil and then hung 2-3 of
the planks at a time in the steam but above the water (wire coat hangers are
ideal for jury rigging the hanging arrangement). After about 10 minutes the
planks will have softened sufficiently to allow you to shape them into
following the curve of the pot. I used two car webbing roof rack securing
straps to initially hold the planks in position & then, by tightening the strap, to
curve the plank to meet the curve of the pot. Leave in position for about
15mins until dry and you have a nicely curved wooden plank. WARNING -
unless you have more than 2 hands don't try & do more than 2/3 planks at a
Securing all the planks in place once you've finished can be as
easy just using the securing straps but I thought I'd do a nice looking job by
routing two shallow grooves across the plank before steaming and insetting
a couple of home made brass securing straps. Coat of dark varnish on the
outside & that's it - looks like a proper still & even after 10-15 hrs of operation
the outside gets no more than hand warm !
My column was too small (54mm dia) for wood cladding so I just
went down to a local industrial plumbing warehouse & got a 3m length of
standard industrial foam pipe insulation - works even better than the wood
but doesn't look so good.
