are screw on BH's indexed?

OK. Now I understand what you are doing.  You didn't indicate that you fletched the arrows after you did the nock manipulation. 

However, what you are doing does create a different issue.  Most carbons have a stiff side/orientation.  Just like with woodies, I usually align my nocks so the stiff side is perpendicular to the bow side plate and then I fletch the arrows.  If you turn the nocks to align with the broadheads before you fletch the shafts, the stiffest spine orientation may or may not be perpendicular to the bow side plate will not be equal from one arrow to the next. Probably not enough to worry about though.   

yeah sorry i didn't explain my method as well as i could have.

i agree with your point about the spine index of the shaft. i found the same thing with gold tip expedition hunters but i changed to easton axis and have found the spine to be very consistent all round the shaft.

you could still do what you do with the spine indexing and achieve glue on heads that index the same. you would have to spine index, fletch then lastly glue in the inserts in the arrow using a BH that has been previously indexed the way i described to orient the insert to the required position according to desired BH position.

Just use Big Jims hot melt glue and you can "index" any head by heating and turning

Maybe file the insert for fine tuning? I would doubt if inserts are exactly the same.
This is one of the reasons I like 3 blade heads. it doesn't matter.
But I can't stand if my 2 blades aren't all turned the same way.

My experience has been that they are not. But that could be some insert issues as well.

Currently I use hot melt. So I can heat up the head and twist it to where I want to be. It works, but is not perfect.

It wouldn't surprise me if the higher end machined broadheads are. Valkyrie, cutthroat, vpa etc.

But for normal components you've got two sets of threads to worry about. Insert and broadhead. Obviosuly both would need to have the thread machined the same from part to part.

It really wouldn't be hard. Just implement your machining processes such that you start at the same spot every time. I would think cutthroats and vpas likely have similar threads from head to head.

But there could be a market for inserts that have identical threads from part to part. hint hint, wink wink...

That way any broadhead that's indexed could screw in to any insert that's indexed and every broadhead would align the same and any arrow.

I got some little rubber O rings that let me do the fine tune but since I use steel adapters and glue on grizzlies for the last twenty years it's not a problem any more

I use several different screw on heads; German Kinetic, Magnus Stingers, Eclipse Werewolf, and Wasp Traditional. None of those brands are all indexed the same.

I like my broadheads all lined up so that they are horizontal when I am at full draw. I shoot Easton FMJ shafts with brass inserts. I came up with a really easy way to line them up. That is to use a torch (or you can even use a lighter in the field) to heat up the insert and rotate the head till it is lined up correctly.  This works well because I use Big Jim's Quick Stick glue on my inserts. Once lined up, they are only true for that one shaft though.
