As far as I know, for the standard vertical head on a Deckel FP1 or FP2, etc., there are three main options for the drawbar and its connection to tool holder:
1) S20 x 2mm buttress thread female socket on the drawbar, original to Deckel
2) M16 male threaded end on the drawbar
3) 5/8" x 11 TPI male threaded end
If you were starting from scratch so to speak, with a Deckel mill which had little in the way of tooling, which drawbar would make the most sense to go with? I have the impression that changing out the drawbar is simple enough to do, but is not something one would want to be doing frequently as it requires some head disassembly (?)
Years ago if you were in the US, obtaining Deckel S20x2mm tool holders would have been a bit more difficult that it is today. I get the sense though that the range of tool holding out there will be more limited in the Deckel standard. I imagine M16 internal thread on the tool holder would be most common, and have the greatest range of options? Or is it really no issue?
Is keeping the machine 'stock' with whatever drawbar it came with somehow meaningful in terms of future resale value, or not?
Does one of those standard drawbars have any special mechanical advantage over the others, or is more durable, or reliable?
If one moves away from the Deckel S20 x 2mm buttress thread, then does one also forgo the close collet system for the machine?
Just groping away here in the dark, trying to make sense of things..
