Fine tuning bowtechs overdrive binary cam

[bowtech experience]

ve you evm move more that the other when you r twisting them both the same amount one the same side? i twisted on my left side of bow because my broadhead was right and one cam leaned more than trhe other one did but it seems to be shooting ok. i just want this thing to be perfect. i drive people nuts with the way i am about this stuff haha

Three full twists or half twists? Like I said, if you need more lean than my pic than it's another issue. If you go further than 2 full twists into the left and two full out of the right, then you risk derailing your bow

Two easy tests. Set your lean close to my pic. Set centershot 13/16" to 3/4" from riser to center of arrow. Then if broadheads are still right of feild points.......

1. Lower your poundage five pounds. If broadheads get closer to field points, then you know your spine is off. Get stiffer arrows.

2. If that doesn't work then I can almost guarantee that your draw length is too long. Drop it 1/2" until your broadheads move to your field points. Within reason, too short isn't good either.

Again this is assuming good grip and proper form. Good luck.

Also keep in mind that your knock point isn't in the center of the string, it's closer to your top cam then the bottom. So if your measuring both from the knock point it's going to look different. The arrow should touch the string equal distances from each cam lobe.

thanks alot guys you helped me out for sure. i got my bow firing bullets now and my center shot is perfect and my knocking point is dead level i have the cams very close to being the same amount of lean and my broadheads and fieldtips are hitting so close together i just moved back to 60 and shot my broadhead and then my fieldpoint and my fieldtip took one of my muzzy fixed blades right off it hit so close. so tuned to 60 yards is good enough for me, i was going to try further but its to windy. thanks again guys. and i am now a believer in the overdrive binary cams i got this bow tuned alot better than i ever got my old monster

Sweet! 

How much pre lean did you end up with?

[demontang]

Good to hear. Im shoot 300spine since 75/95 where to weak, these bows a great to tune and will flat shoot.

For that bow, draw length, arrow length and poundage you do want to have a 300 spine arrow.  7595 or 340 spine arrows would need to be shot at 60# to get proper spine.  I shoot mine at 62# with 27.5" 340 spine arrows to hit optimum spine.  You have proper FOC now with the 7595's, but that will be lost if/once you step up to the Kinetic XT 300's.  You will probably benefit from changing to a 125 grain point at that time.  Will put you at about 11% FOC.

thanks guys, i really like this bow and its at 68lbs and shooting 297fps now and alot easier to shoot than my monster, my monster was faster but ill give that up for this amount of accuracy. i was smacking arrows all evening yesterday even out to 70 so my bow is tuned great for these arrows so im using them the rest of the season. now i ordered gold tip XT hunters in 55/75 the other day, so im guessing they will not be stiff enough for my bow? should i just resell them when they get here?
   jellymon, my cams are not leaning to bad at all now, they are about like yours but not even that much tilt so i am really happy now, and my center shot is right down the center to. this will be my first hunting season in 4 years that i can use fixed blades, and i hate expendables lol so im a happy camper right now. im really glad i found this sight. when i ask questions like this at the local bow shops they look at me like im retarded and say you cant make a broadhead and field tip hit together out past 30, well BS i know i can i tell them. so i was starting to think i was the only one who really fine tuned until i started reading online. im going to try out them 3 blade bloodrunner heads and see how good of a hole they put through a deer. well thanks again guys, i really appreciate all the help.

If mentioning expandable/mechanical heads on this thread it's always a good idea to remind guys you are not hunting in the Northwest.  Otherwise the internet police will have you arrested

My good buddy Del called me this morning from Connecticut.  He said on the way to his stand he saw a number of bucks trailing does.  My brother killed a serious masher in MD a few days ago as he ran a scrape line.  So it looks like your rut is full on now!  Good luck and be sure to share some pictures with us

[bowtech experience]

Haha yea I never thought of that. And yea our rut is starting to get real good I'll be in a tree all day today after 11a.m. I hope to get to try my new bow out this week on a big old buck
