RE: Question about bow square.
 

put your bow square on your string and move it accordingly to were it is centered on your burger button hole above your riser,assuming you are using a flat t-square style.if you are using one that is round center it on the hole,set your rest to were your prongs or what ever raises your arrow touches the bottom of your squaring devise or appears that it would.then check your square were it is on the string and apply nock 1/8 in above center mark.you can start at a straight 90 degrees then tune from there.you dont have to start a 1/8 in high.once you get it centerd on your burger button hole put your arrow on and eye it to were it looks level or slightly high.but what ever arrow you shoot it should be centered on your burger button hole.some shafts are larger than others

RE: Question about bow square.
 

Same here. By recording where the arrow sits on the rest and then aligning the T-square with it you can place your nocking point in the appropriate position. As the others stated though, you are going to need to fine tune it then for the best arrow flight.
