I have seen metal replacements for sale for both the mills & lathes, but I dare not fit them for fear of what my go instead. |

Belts are the way to go I think. If anything goes awry on my Lathe the belt just slips! |

Hi John, The belt conversion is not too difficult a mod if you want to make your own. I did it after smashing my plastic gears through the head dropping unexpectedly as I was adjusting the cutting depth. Having trouble sourcing the correct Vee Belt, I ended up using the round polyurethane belting that uses a brass barb joiner. This has been really good, the green heat welded stuff kept breaking the weld - possibly because of the small diameter of my motor pulleys. I made my pulleys to get a half speed and normal speed ratio mostly I use half speed = more torque. Go for it, you will not break gears cos there aren't any. The belt just slips :D - Way better :lol:. John B |
