RE: How do you guys Fine tune your broadheads and arrows?
I think the first thing is to use arrow spine charts or one of the computer programs and pick a shaft/arrow that is properly spined for your setup. That's item #1. Cut for length, square the end and install the inserts yourself.
Insert installation is simple and there is a sure fire way to get broadheads straight. Here's how I do carbon arrows. Fist prep the shafts, cleaning the inside of the point end with 91% alcohol and a Q-tip. Now---install your broadheads on the inserts. Use 2-part 24 hour epoxy on the inserts. Install an insert in the shaft (with broadhead attached) and NOW you spin test it and adjust as necessary to get out any wobble. This is a step you can't do if using any type of super-glue. OK--now the arrows are ready
Tuning isn't much of a secret either. You can spend a lot of time messing around with different weight points, fletchings and such, but there is only so much you can do with the arrow. In other words, you don't really need to TUNE an arrow.
You tune the BOW to shoot that arrow. The bow is almost indinitely adjustable. Move the rest left to right, move nocking point (or rest) up and down, Play with draw weight. This much easier than playing around with different rrow components or different arrows. And usually it's free.
