Burdick Open Quick Change Tool Post
This thread started my quest for a quick change tool post design: http://bbs.homeshopmachinist.net/thr...ange-tool-post
I settled on a derivative of the Norman Patent Tool Post, similar to the one documented here: http://www.toolsandmods.com/lathe/mini-lathe-qctp
A well-documented inch-based design is here: http://www.homemetalshopclub.org/pro.../toolpost.html
To help share my design I started a GitHub repository under a Cern Open Hardware license: https://github.com/burdickjp/qctp
The repo will eventually contain drawings with proper GD&T and documentation.
The repo currently contains models for:
25mm diameter post
50mm diameter base
0.25in turning and facing holder

I made a bunch of those and they've served me well for years. Add a handle to each tool holder for quicker changes and repositioning. You can also add another tool holder slot if you have a blind threaded hole.
I tried the bottom indexing plate but never found it very useful.
