i got a dozen of my first wood shafts on the way.... will 11/32 bh fit on a 23/64 shaft?

Yes

i know that the head will go on the shaft.  I should have asked if it would have a smooth transition from head to shaft?

like head to shaft. not head, little bit of taper then shaft?...

There is a small transition from broadhead to the non-tapered part of the shaft but honestly is barely noticible and I have not noticed any issues. The picture below is a 165 grain STOS on a 23/64 POC shaft from Twig Archery.



Good luck!

thats what i was wanting to know. thanks.

some are made to fit both - the Magnus two blade is an example. There is no taper showing

Woodmans fit great on 23/64

I use the 11/16 STOS and 23/64 shafts and love them! If you really seat the broadheads good you will hardly be able to tell the difference!  When target shooting, the small transition also aids in arrow removal.

You can do a little hand sanding to smooth the transition especially with FP's-BH's usually are a little more tolerant.
