My next project (and the reason I've made no progress on my guitar for quite a while) is to remove the binding and purfling, cut new channels and glue in new binding and purfling.
I got things a little out of sequence and did the binding before I sanded the sides truly flat. Once I got around to scraping/sanding the sides flat, the binding was quite thin in several places and completely missing in others :-( I also had some problems with the purfling channel having some minor gaps in places on the top.
So now my question: what is the best approach to removing the existing binding and purfling? The binding is plastic and the top purfling is wood herringbone. Should I just let the router cut it out as I cut new channels? I'm worried that the plastic binding might snag and cause more damage. Should I pull the old binding completely off before cutting the channels? It's plastic, and the glue I used (from LMII) does not seem to stick very well anyway. Do I need to worry about removing the purfling? It's wood, so I don't expect as much chance of a disasterous snag.
