Spin testing broadheads

[kennyb]

I am asking for some help regarding true broadhead alignment. My arrows spin true with field points, but when I install the 'woodsman' broadhead it spins just a little wobbly. I have GT Traditional, 3555, and 150g Woodsman, and 145g field tips for practice. I prepared 6 arrows today and 3 spin true and 3 are just a tad wobbly. Any direction/help would be great! I know you guys are awesome for sharing knowledge. Just a preliminary "thanks a bunch" guys!

Try switching the heads around. If that don't work, try a pastic o-ring. Sometimes you can tweak the heads a little with the o-rings.

What kennyb said; I also get the broadhead warm enough to be able to turn the insert in the shaft or the ferrule inside the broadhead itself. Keep at it,you'll get it there.

i showed this to a guy once and it flipped his mind back out your broadhead a quater turn and then spin it it will usually take the wobble out,i userubber o rings and then spin test and i rarely get any wobble

Here is how I have solved the problem of getting my broadheads to spin true:

For screw in broadheads I went to using o-rings in the 1980s. They work great.

For glue-on broadheads I made a little gizmo with wood. There is a bottom board that lays flat on the table. Then there are two little boards with V notches in them glued to the bottom base so that I can lay an arrow in the v notches and it just sits there horizontally waiting for me to turn the arrow as if it was on a very slow lathe.

Then I glued a little vertical board to the end of the bottom base so that the point of an arrow laying in the V notches can touch the board.

I put an arrow with a true-spinning field point on it in the V notches and place a piece of tape on the vertical board. Then slide the arrow toward the vertical board until it contacts the tape and mark where the point makes contact. The point of a broadhead should make contact at the same place if the broadhead is perfectly aligned. Now I just heat the hot glue up and make sure the point of the broadhead is where it should be and when I take it off of this jig it always spins true.

Let me know if you need a photo and I will email one to you.

A little scrap lumber (actually some grooved decking) and some glue to put it together, and I have greatly simplified the chore of getting broadheads aligned.

Best regards,
Joe

smokin' joe-I use the screw in heads, so I will get some "o" rings and I'm sure that will do the trick! at least that's what most people are saying! thank you, sir!
