Given your full situation, my guess is that you know what to do, you just can’t get the repeatable results you are after. 1) if you don’t have accurately squared lumber, you will have descrepencies in your final results(the hex disks). 2) I suggest you cut your post into, say, 18” lengths. This will be more forgiving of inaccuracies of not having a perfectly squared post when you begin.

Other aspects: If you cut one 60 deg. angle, then rotate the log around, you are more likely to have an error in the end. Try(as knockknock aludes to) working from your starting reference surface and working from BOTH sides.

= = = = = = = = = = = = = = = = = = = =

Suggested easiest solution:

Rip to 3.5×3 1/32
Set Tablesaw to 60 deg. tilt
Set base of blade 2 5/8 from TS fence
Rip all 4 remaining sides

1) Make it even easier by setting fence to 2 3/4” from the base of the blade and sneak up on the 2 5/8”.
2) Ignore my 1 33/64” measurement above. Just raise the blade a tad above centerline.
