There are a couple of other options I have seen used in the past.
* Red Loctite on the threads of the arbor/boring head and drilled / pins added to secure the head to the arbor.
* Welding the arbor to the head.
* Installing a RH boring bar upside down in the horizontal bore, and boring from the bottom of the hole UP through the bore. That requires a thru-bore of course (no blind holes) and mounting the work up on parallels to have clearance below the work for adjusting the boring head.
Not ideal solutions but if it works...
One thing I have learned is that a diamond grinding wheel is my friend when it comes to getting a sharp cutting edge on those import brazed carbide cutting tools for use in smaller machines (lathe AND mill).
