I still have a few of the 20 tooth gears I made a year or two ago.
I have sold some of them to people on this list for $20 US. I made
them out of brass with gear cutters I bought from Grand Tool when
they were on sale for a very good price.
Send me a check for $20 ($25 if I have to ship to Canada) and I'll
send you a gear.
E-mail me for the address as I don't want to post it here.
