Hi all,
I am building a classical kit from LMI. Could someone please tell me how deep and wide the binding channels should be?
Thanks

They should be a bit deeper than the binding you intend to use. There is no true answer till you select your binding. Bindings are often 1/16" ( .0625) to .080 thick, Then if you add purfling that can make things a bit more challenging.
The width of binding also will fall between 3/16 to 1/4 inch. This all depends on your selection. It is also best if you can make the binding channel a bit deeper so that you sand the side to the binding and not the binding to the side. http://www.youtube.com/results?search_type=search_playlists&search_query=blues+creek+guitars+binding&uni=1 this link may help you .

John has a whole lot more experiencee that I do, but what has worked for me is to make the channel almost exactly the same depth as the binding. I make a series of practice cuts in a piece of scrap fitting the binding until it just fits. I use the StewMac router bit with the series of little ball bearings - I'll start by measuring the binding with calipers, then make a few practice cuts adjusting both the vertical depth (router base) and depth of binding (ball bearing). I tape a two little 5 degree shims to the router base while doing the back, no shims for the top.
The reason for making the channel flush is that the glue will add a few thousands making the binding stand proud. I like scraping the binding back to the sides, top and back rather than trying to level the the plates to the binding. I'll frequently make the cut in several passes, with the first not quite deep enough vertically - test the fit, then lower the cutter a hair and run around the channel a second time. When I built my classical I used rosewood binding with a very thin light purfling - I was very happy with the results Jun 29, 10 | 6:01 am
