I have the newer y gearbox. They wear out just as fast as the old gearbox. Just ordered two new gearboxes. Its shame we can not order the gear box shaft only. I run my machines 8 hours a day. 6 days a week. Just received the new y box took it apart so I can make a few of the shafts. The metal they use is not heat treated that is why they wear. I going to get the measurements and make them and then heat treat them. I have 6 old y boxes that need this part. Once I make a few and test for wear then they will be for sale. I'm just looking for a supplier for the large bearing. I have gave CW way to much money replacing the y box. Time to make money on rebuilding them. I'm a machinist of 40 years. I have ordered the metal once it comes I'll be turning them. I have a small heat treat machine. Time to put it to use. I need to buy another Carvewright to cut out some of my hours. But this issue has got me looking at different machines that are faster and larger.
