Biggerhammer,
As long as you're not using anything stronger than 50/50 diluted white glue, & you haven't ballasted the throwbar, you shouldn't have any problem.
Diluted white glue, while an excellent adhesive for bonding ballast, & other scenery materials, is ineffective for bonding metal & plastic, the components of a commercial turnout. Like I said, if the throw bar feels like it's stuck after the glue has dried, then MANUALLY move the throwbar, & it should break free easily, & remain free.
Now if you've ballasted & bonded your throwbar, THEN you've got a problem. Once again, keep ballast off the throwbar.
If you feel you need to lubricate the moving parts of your turnouts, use powdered graphite. Kadee makes it, & it comes in a little tube, so you can squirt it wherever you need it.
