Steve. I did say, you'll get lots of advice....... I didn't say we'd all agree! ::) Go for ER type metric collets. They will hold imperial too, as they have a range of "squash down". My mill ("same" as yours), but a Chester Conquest, has a gas strut, which pushes the head upwards, constantly...... Yours uses a spring, which doesn't take the weight at all times. Keep the Z axis lock on, (not too tight), whenever you're not moving the head...... When machining, always keep the non moving slides locked. :thumbup: David D |

Hi Steve A pozilock chuck is fine if all your going to do is use it for milling ,,,, Small shops need versatility IMOP . Clarkson autolock chuck ,,,,,, all it holds is 4 metric collets and four imp collets ,,,,,,, thats all it dose . this is not an ER collet system ,, but close ,,,,,,,, lots of collets A few additions ,,,,, two holders for the lathe ,, two for the mill all using the same collets and closer because there they are bored right through long work can be passed through them on the lathe ,, they also fit the dividing head . On the mill table or angle plate or rotary table in the mill vice , HZ or vertical say for milling a square on the end of a shaft ,,,,,,, or two parallel flats I have a hex one that need to be finished more versatility :med: Rob |

Hi Steve, If you haven't already found the MIT machine shop videos then you might want to watch them. They can be found here: http://techtv.mit.edu/collections/ehs-videos/videos. That should keep you busy for a few evenings ::) Cheers, Jari |

Steve, If you are new to milling this may help a little. http://madmodder.net/index.php?topic=4678.msg51465#msg51465 :beer: DaveH |

Hi Guys, Don't we think Posi-lock is a bit old hat these days? Although they were very good in their day, when most end mills had a thread but these days very few do. An ER chuck is a more universal holding method as it will hold both threaded and non-threaded cutters, and has been mentioned they do not need an exact size requirement as they usually grip over a 1mm range. As for which size to go for, well get the biggest you are likely to need, and don't forget that they can be used in the lathe too. Ned |
