You can't use or I should say they don't make inserts for wood shafts.  There is an screw on point adapter that you can get for wood arrows.  They are made out of aluminum and 3 rivers and custom king carry them as probably many others. You put them on wood shafts with hotmelt glue just like regular points then you can use screw on tips.  Joseph

Thanks Joseph...thats what I meant....I might just stick with carbons...ty mark

You can also foot a wood shaft with a piece of appropiately sized aluminium shafting with the matching aluminium shaft insert in the end-Thta is a somewaht smoother/smaller diameter option but more hassle. Personally I use glue-on points for wood shafts.The whole converta-point concept is overblown- Hotmelt and good point tapers is as easy as point changing needs to get  to satisfy me.
