Anyone know what the A to A is for a Nemesis with the limbs completely relaxed?

That number may be hard to come by, since there isn’t a spec for it.
Maybe someone here has measured theirs and will chime in.
Shoreglide I agree, but I would bet that someone in Florida has that number. Thanks for the response, Bill

What’s your interest in the A to A measurement when relaxed? Just trying to understand what significance it has.
My WAG is to build a press and have it open far enough.

Take your cocked ATA and add 11 inches .

Shoreglide, I broke a string last season and had to press the xbow to install a new one. I thought I might as well build a press that would dissemble the bow if needed. I'll contact Burky.

Sorry Burky, I did not see your post. Thanks for that measurement.

Interested in your press build. I'd like to see what you come up with.

Z, It is a copy of the $20 pipe press with an adjustable pipe clamp section at both ends of the pipe. All I had on hand for the finger was 1/2"x2" material, so it will be over kill when finished.

From what I've seen, even with acme-thread crank on each end, that won't be enough to fully relax yer limbs. Do what you like but for a little more, an very slight changes, you can make this completely safe an effective press for about $60. How-to, parts, an source included here:

You don't hafta build it with the chain drive ifya don't wanta, but it sure is sweet with it.

You should be able to make that work, if you let it down in 2 stages of there isn't enough travel to do it in 1 stage. Count on going from 16⅛" at rest, to at least 22" fully relaxed. How much total travel do you have with both clamps? You will need about 5½" to 6" of total preload travel to let down fully, 2¾" to 3" per limb.

You can crank both clamps out to within ¼" to ⅜" of being fully compressed. Press just enough to remove the string, then let it down to where the cams rotate until just both cables are maintaing what's left of the preload.

Readjust to within max compression, just enough to be able to remove the cables, then you can possibly let it down to fully relax the limbs.

If that doesn't leave you enough travel, there is another easy way to skin this cat.

You will need a longer string and cables. You can use my wedge method to remove cables (one at a time) and replace with longer cables, then let it down. Put the longer string on, pulling back on the slack to remove wedge, relax limbs. Then use pipe clamp press to fully relax limbs from there.

Don't try this unless you fully understand the mechanics. If you need further information, ask for clarification first.

Vent, how much longer string and cables?
Will Velocity string and cables be too long, or too short for an Orion?
I only have 2 1/8" of travel in each clamp, and 4 1/4" might not make it. My original intent was to be able to replace a broken string in the field and I can do that with one complete clamp rather than two. I guess I'll need to build a second press. Thanks for all of the input which is what makes this forum great.

With any scorpyd ignore factory specs

Buy a new set of strings and cables install them then time the bow and you are done

There is no reason to ever try and put the ATA at factory specs because those specs are for brand new bows that haven't been shot and settled in

Once a bow has been shots limbs change as they settle in. So you could put too much stress on limbs trying to get the at rest and at draw ATA to factory specs

3rd attemp @ posting

Thanks to JerryR and everyone else that responded with suggestions and data. This forum it a wealth of information for neophytes like me. I am planning on replacing the ACME threaded rods with longer rods and hope that ACME threads are universal since these clamps are from china. Thanks Again, Bill
