Can I Get Away With A Cxa Toolpost On A Heavy 11

My Harrison 11 inch lathe uses 1" tools in the 4 place rotating toolholder. I am wondering if I can use a QCTP that will hold 1 inch. I have a bunch of 1 inch tooling. It seems that CXA is the smallest size that will hold a 1 inch tool. This is a massive machine for an 11 much larger than my Logan 14.

The compound to center dimension is 1 7/16

Thanks

John
