Brand New Gearset as received from Ed Byers. Precision wheel with matched worm. 

I planned on making GEMs here in the Philippines where I retired, but the local machine shop closed, and it is a 3 hour round trip to the closest one, and I just don't want to leave things in the city. I am selling other sizes, wheels and worms in 9 inch and  7.5  - plus a 4 7/8 with a clutch and a 7.1 with a mounted worm and motor. If you buy 2, I will discount the order 10% - less travel and shipping $ involved. DHL is taking about 8 working days to get these to US addresses. I can ship to other countries, for the difference in DHL rate. I have a rating of 100% with over 1000 feedback on the big auction site. 

#10 is described here with unmounted worm - unanodized,
