Never had a problem with them with a straight arrow matched in spine to bow.  R2

Should I be looking at the head or the arrow I can see wobble in the shaft?

[smokin joe]

When you spin it, look at the head, and especially at the junction of the head and the shaft. If it shows wobble there, then you need to fix the wobble.

If they are glue-un heads, simply heat them  up to soften the glue and tweak them around a bit. then test them again.

[nhbuck1]

How can I fix them for screw in heads with inserts in already?

[Longtoke]

are you shooting woodies? how many arrows have you tested them on?

I have had a woodie out of a dozen that just wont fly with a blade   not sure why maybe just the grain of the wood

[Longtoke]

someone else would be better at giving you advice for carbons,

Other than making sure they are cut straight and the insert is flush i am not sure.

OK so you have heads with adaptors in them.  The adaptors may be glued in with a hot melt glue or epoxy.  

If it's hot melt, just warm up the blade until it's moveable and readjust it.  I usually keep the point on the shaft and push it into a block of wood, turning the shaft as I do so.  This pushes out excess glue and seats the adaptor into the point better.  

Spin it like a top.  If it spins true, you're done.  If not, can angle the shaft on a flat surface and press down near the front of the blade to push it one way or another to align it properly.  Do this until you get it straight.  May need to reheat a few times to do this. Be careful you don't get the shaft too hot.

If someone has already filed the blade edges, they may have changed the position of the tip, moving it off center.  If this has happened, the blade won't spin true regardless of how well it's fitted on the adaptor.  About all you can do at that point is attempt to true up the point, or simply eyeball it to get the best fit you can.

If the adaptor has been epoxied in, it will need to be separated from the head and reglued.  To do this, will need to take the point/adaptor out of the shaft and heat it until you can separate the two.  Be sure to take the assembly out of the shaft.  May need to get it very hot, and it would damage the carbon shaft.

Then, try to clean the adaptor and inside of the point ferrule as best you can and glue back together with hot melt glue. And don't use too much glue. Good luck.

As far as what attitude to mount them , if find old pictures of the more famous archers , you will see that there two blade broadheads are mounted 3 and 9 o'clock .
There has been mention that when you release , the paradox is side to side and a vertical blade can grab the air and start steering the arrow off line .
That made sense to me , and I always mount mine horizontal .
I have not had them shoot any different than my field points .

[Pine]

I will add , that you still need to spin test them .
You can take a cardboard box and cut small "V" shapes on opposite sides and lay the arrow in and with the point near some object , rotate the arrow and see where the very poine is on the reference spot .
That's just one of my cheep tricks .
Buy the way , I use a shoe box and it doubles as a container for archery stuff .

I shot them for years. As long as my arrow spine was good the heads flew great.

Very good advice above.

[nhbuck1]

Would the tip being broke do anything?

[Pine]

It could if it made the head off balance or if it was bent .

[Yellow Dog]

They must spin true to shoot well. I'll glue them to screw in adapters and give them a spin, trying to get them to spin true before the glue sets. If they wooble after it's hardened I'll spin and find the high side and put the tip on a piece of wood and with the arrow at around a 15 degree angle to parallel put a lot of pressure on it to get it to move. Spin and repeat a couple of times and usually you can get them spinning true without having to put heat to them. If you don't get them spinning true all the tuning in the world won't get them to shoot consistently, but that's true with any broadhead. I mount mine in line with the string but that's just a personal preference.

[Orion]

nh,  Of course the tip being broke will affect the ability to get the head on straight.  Would not affect flight if the head is aligned properly.  After all we've already offered, wouldn't that be obvious.  Are you trolling or a newbie?

What Ryan said unless you're using some tiny feathers.

I've had a whistle or so years ago when I for some reason decided I was going to try short adapters...

I bet the whistle you're getting is from short adapters am I correct?

[Longtoke]

Just wondering why shoot adapters when they make screw in? Is the glue on with  steel adapter a more solid set up?

[Terry Green]

Screw ins DO have adapters....they just come already glued in.

I like to glue my own...I can chose the glue....hot melt or epoxy...depends on what the arrow is intended for....

AND,,,, I can align for true spin.

I use long aluminums....have since the 80s

[Longtoke]

Ah good point. Thanks

Here you go...

[Hud]

Yes, use to shoot them a lot. Be sure to spin test them. The shaft and nock need to be straight, or it can cause a wobble and when you get the head finally straight, it will still wobble. Roll it over a glass top table, or buy a spinner.
