| Top 10 mods for Mini lathe please ? |

Buell -- #1) Line up and "fix" your tailstock (tapered) bore to be concentric and aligned your spindle. #2) Change your tailstock over to a "cam-lock" clamp to your bed. #3) QCTP. Others will occur to you as things progress, but this is (from my view of the universe) the places to begin. In terms of item #1, my spindle was out of concentricity by (nearly) .015 in and out of alignment by (about) .005/inch of tail bore travel. In terms of item #2, I cannot tell you how much time is saved each day because I do not have to "find" the wrench to tighten things. In terms of item #3, think about it... Here's a "How To" document. |

Hi Buell, There is a wealth of information in the Yahoo Group for the 7x12 Mini Lathe user group. see betagroups.yahoo.com I joined the group several years ago and have made a number of mods to my lathe. Hope you enjoy your modding as much as I have. Cheers David |

I can see I'm going to enjoy this Forum...lots of good ideas from Guys that Know this machine very well...ummm looks like I'm gonna get to know it intimately. I have rebuilt bike engines..car engines all to an acceptable level but the tolerances on this in order for it to perform correctly ....well they have to be spot on ! Go slow with me guys ! Thanks for all the ideas already ! --- Quote from: Lew_Merrick_PE on November 28, 2016, 10:40:38 AM ---Buell -- #1) Line up and "fix" your tailstock (tapered) bore to be concentric and aligned your spindle. Sorry not great with the terminology ... My dyslexic ness in basic terms.. Make sure the two centres are in line with each other ? Being tail stock and centre of the chuck ? Tapered to concentric what's that about ? Any link would be Fabtastic . Thanks again --- End quote --- |

I have a somewhat older version of the mini lathe from Einhell. The two important mods I did were to replace the ball races in the headstock with taper roller bearings and to remachine the tailstock base to remove the play. I think that it is referred to here: http://www.modelenginemaker.com/index.php/topic,2866.msg49175.html#msg49175 |
