The major advantage to the Van Norman style QCTP? is that it can be made on the lathe. No milling machine? or even milling attachment required. Useful, yes, but not required. ;)
The Aloris style is quite complicated, and requires a well-equipped shop & a skilled metalworker. I'm closer to that now than I was in 2015...

Ah, I had never heard of?Van Norman style QCTP so I chekt it out online.? Yes, definitely would be easier to make than an Aloris style QCTP--however,? the ability to change quickly tools, is hindered by that tightening bolt.? Also, the tool holder itself (many of them) would eat up a lot of metal and a lot of time.? In making an Aloris style tool holder (not the post), you can make several in one go then cut them up .? There is more initial work on an Aloris style but the benefits IMNSHO (in my not so humble opinion) FAR outweigh that extra work.? Besides, most of the work is simple drilling and tapping.? Cutting the bevels is the part that is hardest because of the precision needed and the possibility of breaking a couple bevel cutters.
