What are the standard diameters for wooden dowelling. I don't want the
downright specialist sizes please because I hope to find it at one of
my local DIY superstores!

My application is to use a very short length of dowell to replace an
AAA or AA battery in order to run an electrical device all day. The
dowell would have a drawing pin at each end with a thin wire attached
which is connected to a 1.5volt power supply at the other end. IYSWIM!

The cell diameters are as follows:

AAA cell = 10.5mm (0.42") diameter
AA cell = 14.5mm (0.58") diameter

What alternative material to wood could I use?

You can buy dummy cells for this very purpose.

Really? I thought dummy cells were 'short-circuit' - the OP wants to
fit a PSU across the 'cell'... :-)
