There's a firm on eBay offering 170 mm EN24T 50 mm long for £47 inc carriage - maybe that not too bad :scratch: https://www.ebay.co.uk/itm/Black-EN-24T-817M40-Metric-Rounds-50mm-to-200-mm-various-lengths/193338176672?ssPageName=STRK%3AMEBIDX%3AIT&var=493530085900&_trksid=p2060353.m1438.l2649 |

Just like finish machining a backplate for a chuck. Phil. |

Scary CNC machining that second side Phil when you can't even see the work piece :bugeye: I'd certainly have to make several trial pieces before committing to the final one but I do agree it's the best way of ensuring concentricity ! |
