Hardening Timing Gears?

["Andrew Murphy" <solex67@hotmail.com>]

All,

After the king's ransome I paid for my U20 timing set I am looking at ways 
to protect my investment. One list member recommended that I get my timing 
set gears hardened by a machine shop. Is this the same as tempering? He said 
it would be the last set of timing gears I ever needed.

What is involved? Thoughts?
