Yeah, I missed the secondary point in your second post. Sorry. I still stand by my original arguement.
Regardless the quad holder effectively defeats the quick change that favors the original Aloris style QCTP in the past. You are stuck with four tools and to change them means to stop, grab a tool, unlock the holder, lift out and replace, re-lock. Not a major evolution but a time drainer that should be considered if the quad post is to be retained.
I can see the quad post would have virtues if the lathe was runnng parts requiring simple tooling but more than four tools would seem to become a minor bottleneck. I've had jobs that required a dozen tools, groove, radii, trepans, funny champhers. hose barbs, etc.and the Aloris and the Multifix do well because the tooling is mountewd in individual blocks quickly exchanged.
Frankly I wouldn't have that quad post for free. Yes. its accurate if no chips or debris are trapped in the registers. Otherwise there's no advantage. It's bulky and lame compared to the flexibility and compact envelope of the original Aloris, Multifix, and similar QCTP. The 24 positions is no particular advantage, especially for short parts supported with the center. Kinda like a boat anchor in a punchbowl. Find a sucker and unload it.
