So school me on collets. The bore taper is fooked on the lathe. So I'm going to have to make or buy a collet chuck. Something common would be nice. Should I go with something like an ER40 for it's wider clamping range and so I can use the same set of collets in the mill? Or should I go with a 5C setup because it will hold a larger dia and fit my spin indexer? Maybe adapt the spin indexer to ER40 and use the same collets in all three? I do like the larger capacity of the 5C, but they won't work in the mill and you have to buy more of them to hold odd ball diameters. I just don't want three different types of collets floating around. Simple is good. I currently only have one 5C collet and maybe 8 R8 collets. If I went with the ER40 then I could ditch the R8s. I don't have sizes to match all my end mills anyway.
Any other options? Am I missing something? I don't care about which is faster. Not doing production work here. No CNC equipment to worry about either.
