To Tim; and other interested parties here are some pics of a Swager.
Here is the clamp Note the holes are marked to aluminum arrow sizes.
Insert and tighten arrow in the appropiate hole , leave approximately 7/8" sticking out and position the clamp on drill press bed.
The actual Swager is the little drum sander looking thing on the right, install in drill press & set drill press to turn @ about 1100 RPM , i also use some lubricant like STP . the hole at the top of swager is foe venting.
This pic shows the other end of swager that has a 5 Degree taper machined into it. The swager is made of D2 steel which has a high Chrome content.
