I believe it would work but the smell? You would be burning/melting through the CA with friction. Might be a bit TOXIC!
I use conical bushings made from UHMW plastic I picked up at Woodcraft. Cut it into blocks about 3/4" x 3/4". Drill with 1/4" bit or the diametter of your mandrel. Mount them up and turn to a cone. You can build with 7mm tubes inserted but I like the snug fit of just drilling.
