GROZ TYPE QUICK CHANGE TOOLPOST

These are preliminary pictures of an alternative style quick change toolpost.
This is quicker to make than the other one and is about half an inch shorter (the tool is closer to the centre).
This is the one I use all the time.

This picture shows the basic design of the tool post. The tommy bar operates a long screw that clamps the split part tight on to the tool carrier.

And another.
