This ad is for a complete set of OEM change gears for a Craftsman 109 bench top metal lathe. Please note that the lathe photos included in this ad illustrate the types of machines these change gears are for, and are being used for illustration purposes only. I am NOT selling a lathe, only the change gears. If you purchased one of these machines without with the set of change gears for threading, here is your opportunity to purchase the real thing. These are made from actual metal, and are NOT the junk plastic gears they are selling on Ebay! I am asking $75.00. Cash only. Questions, call or text 585 - four five five - 0121. Yes, they are available. Thanks for looking.
