So with the 1/64" shims, how do you make separate down and right adjustments without affecting each other?

They may affect each other!
I view the noseblock opening as a clock face and therefore if I want just down
I set @12 o/c. If I want some down and right I set the shim @ 1-30 o/c.
If I want right thrust only Ill set shim @ 3 o/c.
On radial engined models when I see that a fair amt of thrust offset is needed Ill make
up a balsa ring (picture a large balsa washer) that has one surface sanded to an angle.
Then this is mounted so that the high point is @1-30 o/c.
Rectangular noseblock style I simply build up with strips of 1/8 sq and dress the front with a sanding block
so noseblk isnt rocking. Sanding in a manner that approximates your desired compound angle.
All of this will not preclude added thin shimming as trimming progresses.
Be aware that too much shimming can cause a wobbly noseblock.
When this happens I resort to one of the above method.
