SMALLadjustment to the rest probably won't hurt you with the 3rd but that is what makes that little gadjet that I linked too so great,very simple to use.

AND NO,I DO NOT REPRESENT THEM IN ANYWAY,just a great product imo.

The 4rth is totally irrelevant to how well a level will perform,but when adjusting your 3rd,the fourth is the easiest way to get it right because the 3rd is easiest to set off the bar of a slide bar sight and the 4rth can be used to shoot it in.

basically you square the sight with the sight bar on a fixture and then mount on bow.(most stop here but the sight isn't square with the arrow and it is another plane you need to be square with!!!)Then you just adjust the 4rth axis,(sight bar) with the arrow and you are set perfect for any angle shot you wish to take.

I did not twist the level at all.I actually tested this level on a completely level surface at work.I was able to shim the level on 1 end and reset the level with the shim under it and it still be level when I laid it down,proving that the level in the protractor wasn't square with the next plane as I rotated it over.(The level stayed in contact with the surface the whole time)



The level that I made can be spun in a circle on the same surface and show level all the way around.


The 3rd axis has to be set perpendicular to the arrow PERIOD,your grip style comes into that equation and that is a good reason that the 3rd needs to be checked when shooting the bow.The 4rth axis tool does that.

I would like to add that this isn't an easy concept to grasp for most.It took me awhile before it started "making since" in my head.

Once it clicked,it is so simple it is scary.

Don't worry if it isn't popping in your head right off,it will come if you really want to learn it and are trying to setup this kind of equipment.

"T" I cant remember if it was Gene, Ken or both who where posting those pics (I thinkI have old timers setting in )

But your right it is so simple it is scary it just sounds hard

great, I'm still chewing on papertuning, walkback, french kissing, euh, no, it's french tuning...and all of that...

and this is something else, I'm ordering the G5 Optix sight in a few days with the help of DavePjr and this doesn't make sense to me at all....

well, I'll wait until I get my sight and then start panicing !!

TFOX,

I just read another article that talks about 3rd axis tuning. They basically say to adjust the 3rd axis shooting parallel to ground and then adjust it by aiming at a 45 degree upward angle. This is supposed to eliminate errors for up or downhill shots.

I stated that earlier,there are 2 ways to set the 3rd axis.Shooting it in on a hill was one of them and is a very accurate way to do it,but,imo is a more tedious way to do it.

I do most of my tuning at home and I don't have a long 45 deg hill either.

Don't overthink this,it is not that difficult and isn't nearly as important on a hunting bow as it is on a target bow.

I don't even have a 3rd axis adjustment on my hunting bow.

thx for those comforting words T, I needed that.......

Is really important at all, on any kind of bow. I mean all it really is, is to check for torque at long ranges right? So it is just a referance it doesn't affect accuracy at all does it?

WRONG ,you totally missed the point of this whole thread.

If you watch your bubble and it isn't set right,you will cant your bow to get the bubble right,but it will be lying to you.

If your 3rd axis isn't set right,when you shoot a target downhill at 40 yards,you could be off several inches.


Now think about those that shoot uphill at an 80 yard target.They could miss by a foot if the 3rd axis isn't properly set.
