Gents for who is interested,

Spar(s and)ribs and a look in the D tube.

I do glue the spars and ribs together without any needles, tape, magnets or weights.

First the ribs, spars and shear webs and later the nose LE and TE spars.
By using white wood glue the fixation I can make by holding each joining for a while.
Each spar, LE and TE, has saw slots on the position of the ribs.
These slots in the LE and TE spars I draw on these spars by laying them on the ribs near the main spars in the right (swept?) angle.
Normally, using spruce main spars, I glue in the shear webs later and build the wings mounted together.

The triangle main spars look good to me.
