I saw these on Ebay uk and thought they looked good for the £47.00 many suppliers were offering and also i liked the adjustment was for the diameter you were making and not the radius so i sent for one.
And I was impressed with the quality at first but when i fitted it to my milling machine i found the Morse taper was too short and barely caught the the thread. So I checked it against my other fittings and found it was about 5mm short. Most of the others have about 5 turns to screw in which is only 3 thread anyway, is this normal. Also I have now noticed that the holes for the boring bars are a little off centre towards the cutting direction so will this still work, looks to me as if some errors have crept in and they are being sold off. Has anyone bought one of these.
