I'm worked with nothing but Hoyt cam and a half systems for a long time but have a xring 6 coming and need to know how to time the cams. Pretty much clueless on a hybrid.
Thanks a lot.

ALL hybrid cams have these three things..

a) a bowstring
b) a buss cable, also called a yoke cable, and old timers call it the POWER cable...so, this means it is Y shaped, has two yoke legs, that attach to the top axle
c) a control cable, a rope, has two end loops.

First
for ALL hybrid cam bows...

the Max draw weight is controlled by the buss cable.

The BUSS cable squeezes the limb tips closer together
the BUSS cable squeezes the limb tips farther apart.

Sooo,
you bought a 900 lb draw weight bow.

BUT
BUT
BUT
the limb bolts are maxed out
and you ONLY get 880 pounds of MAX draw weight.

WHAT now?

Well,
you press the bow
and you SQUEEZE the limb tips CLOSER together.

SHORTEN the buss cable
and you will INCREASE your MAX draw weight from ONLY 880 lbs to
901 pounds of draw weight..if that floats your boat.

THIS works for ALL 900 pound draw weight hybrid cam bows.

This works for 80 lb draw weight hybrid cam bows.
This works for 70 lb draw weight hybrid cam bows.

You get the idea.

When you check the draw weight,
with limb bolts at maximum,
using a scale

if the max draw weight makes you happy,
then,
the buss cable tuning is DONE for length.

If the max draw weight does NOT make you happy,
you can BOOST max draw weight by shortening the buss cable...

try the bottom end loop for STARTERS.

STEP by STEP.

Since you FINISHED tweaking the BUSS CABLE
for MAX draw weight...

then,
we TWEAK the CONTROL CABLE
to tweak CAM SYNC.

Yes,
CAM SYNC...(not timing).

Timing comes LATER.

We fix CAM SYNC.

BUT
BUT
BUT

what about the timing dots?

Dont' care.

what about timing marks?

Also don't care.

WHAT?

RESULTS based tuning.

SHOOT some arrows
and then TUNE the control cable twists
until YOU shoot BETTER groups than ever before!

BUT
BUT
BUT
what about the DOTS, the timing MARKS, timing HOLES, reference LINES, you know

WHAT ABOUT SPEC?

Don't care.

We are going off of RESULTS,
instead of dots, holes, lines, marks, etc.

The dots, holes, lines, marks are a suggestion for a GOOD starting point.

STILL gotta shoot the bow
and see what size GROUPS you get.

So,
let's go to the shooting line
and shoot some ARROWS

to figure out WHAT to do with the CONTROL CABLE.

THIS applies for ALL bows....ALL Cam systems.

20 yards.

FIRE a bareshaft arrow
and SIGHT IN the bareshaft arrow
until you NAIL the x-ring.

I added a LEVEL strip of masking tape, as well.



I fired the BARESHAFT FIRST
cuz,
that is what came out of my quiver FIRST.

BAM

nailed the bullseye at 20 yards
AND
AND

nailed the TOP EDGE of the masking tape.

How about that?

heheheheheheheheheehehehehe

The idea of the CONTROL CABLE
is to fine tune VERTICAL CONTROL.

PERIOD.

Soooo
to AVOID killing my BARESHAFT nock...

I fire the FLETCHED arrow
over towards the LEFT SIDE of the MASKING TAPE.

BAMM

nailed the TOP edge of the MASKING TAPE.

THIS is vertical control.

THIS is how you tune a control cable...

you only need a half twist,
maybe ONE full twist

to DIAL in your SWEET SPOT.

Sooo

WHAT does this MEAN?

YOU SIGHT in the BARESHAFT
MOVE your pin UP
MOVE your pin DOWN

until YOU nail the bullseye at 20 yards

UNTIL YOU can fire a BARESHAFT and NAIL the top edge of the MASKING TAPE.

IGNORE NOCK HIGH, NOCK LOW, NOCK LEFT, NOCK RIGHT....that's a different problem, and has ZERO to do with the control cable.

So,
you FIRE the BARESHAFT
and the FRONT END
NAILS the bullseye
and the FRONT end of the bareshaft

(tube with NO vanes...just a nock, just a point...NO tape on the back end....COMPLETELY remove the vane)...cuz we want ZERO airflow disturbance


NAIL the bullseye,
and SIGHT in your bareshaft.

So

the MOMENT of truth.

AIM towards the LEFT side of the tape
and FIRE the FLETCHED.

IF your fletched MISSES HIGH or LOW...

goto the PRESS
and SQUEEZE the limb tips
and PICK a direction.

Let's try REMOVING a half twist.

BAck to the 20 yard shooting line.

FIRE the FLETCHED.

STILL MISSING LOW

BACK to the bow press.

REMOVE another half twist on the TOP of the control cable.

BACK to the shooting line.

KEEP going until you NAIL the TOP edge of the masking tape
with the FLETCHED ARROW.

Double check
and fire the BARESHAFT arrow.

YOU want the EXACT SAME height,
for the FRONT END of the fletched arrow

YOU want the EXACT Same height
for the FRONT end of the BARESHAFT arrow.

See.

EASY
PEASY

What happens
when you DIAL IN the TOP end loop of the control cable
this way?

When you IGNORE spec?

YOU are now HALF way to groups like this.

at 20 yards.

What about the draw stops? Do you move them or time them with the buss and control like a cam and half?
