I am prospecting around for a used collet chuck for my lathe which has a L-0 spindle. It appears that there are at least two types available which I could use that seem readily available: Sjogren-Hardinge and Jacobs rubberflex. I have only used Sjogren ones previously. Are there reasons to favor one type over the other? I know that the rubberflex collets have a greater range of adjustment and so fewer collets are needed to cover the range of the chuck's capacity. Is the accuracy of the two types significantly different? Do the metal jaws of the rubberflex chucks hold workpiece better or worse than the solid metal collets? Do they leave bite marks? I would appreciate any comments or suggestions about these things. I would be using the chuck mostly for personal projects. I don't know whether a good 3-jaw chuck is just as accurate as a good condition collet chuck. Leo Plas
