I have a bow that has been put for years and I am about to start shooting it again. how do you know if the limbs are at the same poundage without any scales or tools. Cani crank the screws ali the way down and back them off again? thanks

If you put tham all the way down you will be at your maximum poundage. Back them off equally for lesser poundage.

If your bow has been sitting for a long time you might want to make sure your string and cables are fine to shoot. Sometimes leaving a bow sitting too long can dry out your stirng and cable depending on how it was stored. If you can get by a bow shop to get it checked out, it may be in your favor.

Wax your string well.
Graphite all moving parts like cam axles.
Cranking down the limbs does set your bow to it's maximum poundage which should be on a sticker on a limb somewhere. If that is too heavy, back each limb adjustment off equally. One turn should be about 2 - 3 pounds.
I think I would have a tech look at it first. I've never had a bow blow up next to my face, and would take every precausion to avoid that! (lol)

thanks for the help I will take it to a shop and let them see if it is alright. Deer season is over down here so I will take it in March before turkey season.
