| Making an accurate spindle with an innacurate chuck. |

am I correct in thinking what you are saying with the chuck on its back on the surface plate, the top face where the jaws fit is not parallel to the register face looks like its duff if it is but it could be remachined to make it correct , but now its a whole new ball game looks like you need someone with a bigger lathe to mount your chuck ( when griped to a known bar ) between centres and true up the rear face to the jaw axis ( but you have ground them but it could work out ) if you go for a new chuck get a bison they are not cheap Stuart |

Am I correct in now assuming that this is a second hand chuck? And continuing the same theme, am I correct in thinking that the jaws are loose in their guides? True, you can tart a worn chuck up-------------------a bit but you'll never achieve any accuracy worth mentioning other than ONE diameter. I would like to be wrong- but that's show bizz.

There's burrs all over it too. I bought the thing from Chronos at about the same time as getting my lathe, and I remember being a bit surprised at how rough the thing looked considering i'd spent something like £50 on it (I can't remember exactly what I paid). I wouldn't buy from them again. --- Quote from: lordedmond on November 21, 2013, 10:54:35 AM ---if you go for a new chuck get a bison they are not cheap --- End quote --- I think if I ever start to get real money (i'm currently living off of a small student loan) i'd just spring for a real lathe second hand. But at the same time I keep hearing stories of people just flat out throwing perfectly good lathes away. The folk at the school my mom works at did the whole 'ohh if only we knew you were into this stuff a few months ago! We didn't have the space when we moved to the new school so we just threw everything into a skip!', a fella my grandad knew died of cancer and the first thing his Scottish relatives did when they inherited the house was sold all of his carefully collected equipment and instruments for scrap. Real tragic, but it makes for a frustrating situation when it comes to the price of second hand tools. |

2 years ago, I found a almost perfect Myford ML7 with a gearbox and long saddle for £400. It needed a set of chucks but it had been slideways ground and would have served someone for the next 1000 years. No one was interested yet the box alone was worth more than that. I was too old to be interested as I had a lathe bed done- by the same local firm. A guy got interested in my little Unimat clone which I 'd bought for £250 and it came almost unused with two chucks, faceplate, tool posts etc and a set of ERX 16 collets. He spent a day 'kicking my tyres and my temper and took it home -and brought it back -because he didn't know how to check the speeds. That was his story! On Monday, I put had a Quorn- for all of a ton(£100) and the guy has showed no further interest. A few weeks ago, I offered a freebie of information- and a bloke here -couldn't be arsed to collect. A few weeks ago, I had a call and someone wanted a Myford tray and expected that it would be cleaned, delivered and probably fitted for the Square Root of Bugger All. So I can understand why 'the skip' is so popular. My kids are not bothered for a few quid from me- and a skip is written into my Last Willie and Testicles. We live, young Sir , in a situation where we can all play the same silly, selfish and indifferent game. Meantime, I wish you luck Norman |

I can never understand people who take the mick like that. But then i'm the kind of person that can't browse a small shop without feeling like I have to buy something. Speaking of that Myford though, I've never been too sure where to even look for second hand tools in this area. There's one second hand shop on the way to Consett that very occasionally gets tools in but the guy likes to use ebay as a pricing guide. |
