Need help with measures on my JEM style project

Hello everyone, I am making templates for my JEM style build. I have that old picture of JEM777 blueprint as a base of my templates. I have calculated and measured everything and came up with a conflict of numbers on where the neck should be.

So basically I have scale length of 648mm (roughly about 25,5 inches) and edge installing manual says that on 25,5" scale, tremolo mounting posts should be placed 637mm away from the edge of fingerboard.

Then there is that basic idea that neck pocket ends exactly where 16th fret is on the neck. 16th fret is 390,841 mm away from the nut.
1) Blueprint says that distance from the center of posts to the edge of neck pocket is 245mm. When I subtract that fret distance from post distance result is not 245mm, it`s 246,16 something. With exact scale (25,5"-647,7mm) distance grows even higher.
2) Is Ibanez toplok the same size as any locking nut ? Width 43mm and depth about little over 15mm? I don`t have any parts yet...
I have Floyd Rose bridges and I know you can adjust the intonation but I would still like to try and make it as accurate as I can. Also goal is not to make an perfect copy of Ibanez JEM but my own guitar.

Where am I going wrong ? Thanks

Why are you complicating so much ?
Just make the neck pocket, insert the neck then measure 637mm from the nut to get the posts at the right place.

Yeah I quess you are right. Maybe it`s because I have been staring those plans and not started to build body yet.

Then again I was trying to figure out templates so everything would be already thought and measured. Would be cool to have accurate templates but maybe it would just make me cut without thinking. This is my first proper build and I don`t want to ruin it from the beginning.

Thanks for your reply.

Get on with it ! One way to ruin a build is by over thinking everything
