Greetings to all,

I am getting ready to cut out my road wheels and began to wonder what I should use 
instead of just axle to wood?  I am using aluminum rod for the road wheel axles (I 
am beginning to think this was mistake because it is just slightly larger than the 
advertised 1/2" dia..) and began to wonder what everyone else is/has been using.  Is 
aluminum-to-wood okay, or should it be sleeved with something.  All suggestions will 
be considered.  Thanks
