Quite an involved project.
I suppose if you had the stock lying around and have plenty of time to kill it's a fun thing. What kind of cast iron is that? It would appear to be a simple, soft gray cast iron rather than an 80Ksi ductile. Looking at the piece it appears to be a tiny chunk of a huge machine or heavy equipment.
Just so I'm clear, are you saying you are going with a more conventional type of QCTP that would accept simple one-piece tool holder block? In the top photos I see a two piece dovetail configuration that seems a lot of work. and plenty of opportunity for loss of rigidity. Even the idea of the indexing with that tapered screw/post style seems suspect, and no other lathes that I know of use it. It's mass does seem good though, no denying that.
I wish you the best and look forward to seeing your improved design for the tool block to post connection.
