Can I pick your brains please.

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?

Thank you.

What about a dead AA or AAA cell - should be about the right size -
bit of insulting tape over the ends to prevent it interfering - add
the wire as planned
