[luatex] how to assign a width to a node of type "glue"

I'm trying to create a glue node that has a specific width. Unfortunately, I seem to be missing something (probably entirely trivial to somebody who knows how it's done).
Here's what I've tried so far:
local glue = node.id ( "glue" ) -- 10
local gluespec = node.id ( "glue_spec" ) -- 47
local gluenode = node.new ( glue ) -- create the node
gluenode.subtype = 0 -- "skip"
-- what next??
I would like to make this node have a width of 0.03em (no stretchability or shrinkability needed).
The LuaTeX reference manual (p. 178) says that I should do something with the node's field called "gluenode.spec". If I understand the manual correctly, this field should be a "pointer to an item of type 'glue_spec'." However, there's no indication on how this should be done, and the explanation of glue_spec on pp. 173f. is even terser.
This is where I'm stuck for now. All help and suggestions will be much appreciated. Best, Mico
