While I am waiting for the electrician to return I figured I would get a few whatnots knocked off the list. First I am starting to fine-tune my mill. :proj: My extended Z axis rack will be here tomorrow. In the meantime I eliminated a BIG hunk of Z axis backlash: I never understood why they put a u-joint on the fine feed mechanism...to get past the p**s-poor alignment of the rest of the system perhaps? Here's the solution: When I change out the rack and replace the torsion spring with a counterweight I will shim the rack to get better engagement. By changing out the u-joint with a solid rod and peening the castleated clutch (I forgot to mention that) I got my backlash down from almost .070 to a much more acceptable .025. And finally a rack for my R8 tooling, collets on the spinner endmill holders in the back: Not huge projects but they were fun. |

Hi Websterz Interesting couple of modifications you've done there :clap: Have Fun Stew |
| Stilldrillin:
2 nice mods there Websterz! :clap: I too wondered about the coupling....... :scratch: Fortunately, mine is still unworn. Backlash is at around .020". Must remember your mod, for later..... :thumbup: David D |

Websterz, I have the Grizzly version of that mill. I could never understand why they had the u-joint either. Kind of makes sense now that you mention it. Nice little projects by the way. Do you know if your lead screws are 16TPI or 20TPI? There's a mod to change them to 20 TPI from Micro Mark. Check out my website on the write up I did of the my mini-mill. Regards, Bernd |
