Jeff, I have found that glass that has been applied with thin CA usually peels of pretty easy. What happens is that the cloth saturates with the CA hand keeps it from soaking into the wood much the same way a diaper works at keeping wetness away from skin. What I would do at this point is chop off the dowels, peel the glass off and apply new glass with epoxy resin. When applying the new glass, brush the epoxy resin onto the wood and then lay the cloth down. This will give some penetration into the wood and result in a much stronger bond. Re drill for the dowels, cover and install new dowels with brass sleeves so the dowels wont wear out the holes in the former.
