How do I check for the lean of the cams. I just can't figure it out. I have tried looking at the cam and drawing the bow but it ishard to tell. Is there a special trick?

Pretty easy really. The easiest way is to just hold and arrow or straight edge along the side of the cam/idler so it lays along the string toward your center serving. The arrow will be parallel with the string if there is no lean.

O ok. Thanks BG. I was going nuts trying to figure out how to do it. Just want to make sure everything is in tune. Thanks again.

BG's method works for at rest but you really need to check it at full draw as well. I hold the bow out as if I was going to draw it and eyeball/align the string with the cam grove so it looks like the string is going parallel with the cam then I look where the string crosses in reference to the rest prongs. Then I draw the bow and do the same thing lining the string up with the top cam and looking at where it crosses in reference to the rest. If everything is in oreder and your bow is at least very close to centershot your string should always cross the center of the rest looking at it from behind. If there is cam lean, like on my BowTech, the string should cross the inside of the rest at static position and equally to the outside of the rest at full draw.

The easier/better way is to have a machine that allows you to draw the bow and have it jigged up while you check those reference points with a lazer but we do what we can...

Red,

I don't know what you're trying to accomplish Maybe just checking for cam lean? Take this into consideration as you are shooting a Hoyt. The cable attaches to the upper limb with what is called a floating yoke.

If you have some cam lean and twist up one side of the yoke, you only have to take a couple shots and the cable will center itelf to the same position as before you adjusted it, so twisting a floating yoke is a waste of time and energy. The only way you can get permanent results is to have a cable with a static yoke.

There are guys that have done this and what many do is serve the floating yoke so that it can't shift after the adjustment. Others get a new cable with static yoke built in like other bows.

If you replace the cable you have to order one the correct length. I'm not sure, but Hoyt may list their cable length without including the length for the yoke. You may have to add the length of the yoke to your measurement.

Hoyt has their own reasons for doing this. I don't know why so I won't say one way or the other which is a better system. I just know that they are the only bow company that has the floating yoke.

Maybe someone that has done this will chime in to help.

Yes, I just want to check for lean because I bought the bow used and am trying to get it in tune.Im making sure everyhting is correct so that all of my fine tuning does't go to waste. I have never heard of a static yoke before. Where do you get them? How are they diffent form the satndar yokes? I have not seen any measurement that says how long the yoke is but, does it matter? If you just center the down buss cable in the center of the yoke will that not be fine. It has said nothing about this in the owners manual.

Some hoyt owners have good luck wiyth the floating yoke. I did not. I put a set of Winner's Choice string and cables on my Trykon because I could not get it to tune w/ the floating yoke system.
Like BG said, you can serve the yoke together if the cables are in good shape. This will allow you to tune the lean. It MAY not paper tune w/o doing this.
If you were to ask me about the floating yoke ,I'd change it out first thing. Some will argue that. Just my opinion.
I shoot bullets now. The static yoke also keeps the center shot at a more reasonable measurement toward the center of the bow.

Something else that is critical to tuning a Hoyt is the cable stop timing.
At full draw the cable stops should meet the cables at the same time. You have to max the limbs out and make sure your tiller is even before doing this.
If your back wall feels mushy and the string wants to jerk your arm out it needs set.

OkI understand this, but what is a static yoke, and how is it different from a floating yoke?

Simple answer. Take a look at your cable. The cable is a two-piece affair. The cable attaches to the bottom cam, which in turn attaches to a short "V" cable which then attaches to the upper axle. Got this? This is a floating yoke.

This gets it's name because where the two cabling pieces attach to each other allows them to supposedly self-center all the time. Make sense? And Hoyt is the only company using this two-piece cable.

Now I'll explain this cam lean thing. Most cam lean is caused by the cable guard. The cables are pulled to the side by the rod to facilitate fletching clearance. What this does is put side torque on the cams, which twists the limb tips. So what most of us refer to as cam-lean is actually the limbs being twisted. The undesireable feature of this is that during the shot, as the cams roll over, this cam-lean causes string oscillation in the horizontal plane. The result is oftensideways oscillation of the arrow and right/left tears when paper tuning.

You want more detail about it then get on Spott Hogg's website and read letter #5.

OK, a staticyoke is what every other bow uses. Basically it's just a one piece cable with a "Y" yoke where it attaches at the limb tip(s). With a static yoke the "Y" form at the yoke is not free to self center when shot. Therefore, any cam lean can usually be straightened out by twisting one side of the yoke and will stay that way.
