Thread: ER25 chuck |
21/10/2017 09:51:18 |
Posted by duncan webster on 20/10/2017 21:47:56:
I've got an Autoloc chuck, but mounted on MT2 taper it looks out of proportion, so I'm considering buying ER25. Could someone measure one for me, length and diameter of the body? Don't want to find it's that same size and I can't find anything on the interweb.
I agree about the Autolock; mine has a damping ring which is said to improve its stability. If you were to make your own ER chuck you would have some control over the dimensions. |

..."The more flutes the weaker they get."
I would have been inclined to agree but one authority points out that "The end of the [core] drill ... does not come to a point, as in the case of the ordinary drill. For this reason the web can be made thicker, so that a stronger drill results." |

Core drills need a pilot hole but are otherwise excellent. I think they come in four flute style as well. |

I mostly use the QSM on the lathe but, as a demonstration of its versatility, have added a couple of photos to the end of my Miscellaneous album showing it being used to machine the face of the casting on the head of my mill/drill. I think that if John Payne were designing the machine today recent developments might have made a cheaper result possible; perhaps, eg, avoiding the need for the gearbox. |

The QSM is a very useful piece of kit, sold by Hemingway but production temporarily suspended hence, perhaps, what seems like a premium price. See their website. Drawings are available for DIY builders. Edited By ega on 15/10/2017 23:58:26 |

There's no mention of it in the 1958 B&H catalogue. Nor (according to the index) in the 1964 catalogue. |

Eddy Curr: I very much like the idea of loosening the chuck by repeated blows without immobilising the spindle and will try this if the need arises. Instinctively, however, it would seem that the blows should be "radial" rather than axial and that a hammer tool (as opposed to the mechanic's air wrench) would be less suitable. |

... On a different topic, has anyone made an adjustable carriage stop for the ML7? If so would you care to point me in the right direction or share with me? The Amateur's Lathe contains a design for a stop mounted to the right of the carriage; left-hand designs depend on whether a gearbox is fitted. |

Regards, Tim (the last apprentice at the Guild of handicraft, Chipping Campden, but that was over fifty years ago) I remember being taken there as a schoolboy by someone who needed a repair to a silver salver and being particularly struck by the aprons which connected the craftspeople to their benches; I think I was told that the precious sweepings were carefully collected at the end of the day. |

The MEW article is based on an idea by L H Sparey and described in his essential book The Amateur's Lathe. Correcting myself, the LHS book is A Man and his Lathe. Apologies to anyone who spent time looking in the wrong place! |

Posted by michael potts on 13/10/2017 11:41:53: .... I am in the process of getting one of my EW lathes running. I found it beyond belief that a lathe designed and built post WW 2 used Whitworth threads throughout. It is a substantial machine, but some design features make you tear your hair out.
Mike Potts. I know what you mean. My 1960s Willson has BSW fasteners which are obviously more difficult to get than eg metric or UNC. Fortunately, the market for vintage motor bikes seems to have encouraged manufacturers to go on producing BSW. |

peter blair: I feel sure that if there is a member near to you they would be glad to show you or lend their copy of MEW; unfortunately, like so many other people asking for help, you have no public profile and I don't think you told us where you are. The MEW article is based on an idea by L H Sparey and described in his essential book The Amateur's Lathe. The principle of this method is the same as Steve Jordan's but, to me at least, seems quicker and less messy. Incidentally, I would not recommend standing the chuck on its register on removal as seen in the video as this is likely to cause any chips present to fall into the chuck thread. That said, plus one for the Boa as a generally useful tool. The stuck chuck is more likely to afflict those who leave their chuck in place for long periods and, for peace of mind, you might consider loosening your chuck after every work session. |

Prevention is better than cure. If a lot of heavy, intermittent cutting is being undertaken it is a sensible precaution to check from time to time that the chuck has not become overtight (the same point applies to faceplate work where intermittent cuts are perhaps more likely). |
