Looks like a fine piece of kit and sounds like a good price too. What I can't understand is how you fit / change the collets - surely you don't undo all 6 fixings? |

Oh yes you do Murray ! Not that bad really with a handled hex driver - usually it'll be for small runs of parts. Numerous phone calls today are bringing me round to thinking I may HAVE to make the adaptor plate. So if I do I'll pretty certainly do it on the manual lathe on an expanding mandrel between centres so that I can work on both faces and have some hope of maintaining concentricity. So where do I find a 45 mm slice off a 170 mm bar of something nice to machine? |

College Engineering do Cast Iron bars for very reasonable prices. 50 mm of a 200mm sized round bar is about £58.72 on their website. https://www.collegeengineering.co.uk/product/200mm-7-87-round/ |

Hi All, I must be lucky where I live ? There are a couple of engineering workshops close to me where I can buy off cuts usually a donation to the tea kitty :beer: When I had a job, the scrap metal skip was never safe LOL John |
