I think the bridges will = function very well, but I am aware that my hand notching skill leave a lot to be = desired - I never have been one for art work and I know it shows. However, I = will have my Ron-Nossaman-type notching machine built before I have to notch = another bridge, so my notching results will make a quantum leap the next time I = tackle this task!</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>One of the many things I really like = about employing some of Del Fandrich's building techniques, is one's ability = to toss out mysticism, replace it with engineering, measurements, and the = ability to repeatedly check your work for accuracy as you proceed. The upper = picture below is of the second treble (capo) section of the bridge on this = Knabe I am working on. You can see that the cap is made up of six laminations. = (Please ignore the crappy-looking notching.)</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><IMG alt="" hspace=0 src="cid:001101c5855d$19a20b30$0201a8c0@youro0kwkw9jwc" = align=baseline border=0></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>The picture below is up near the treble = end of the long bridge. You can count eight laminations here. Somehow-or-other, and = believe me I know not how, I measured everything, planed my bridge root down to = the proper thickness, and epoxied on my bridge cap of uniform thickness. = Then I went back and properly loaded the soundboard assembly to double-check things = and found that the treble end of the long bridge was a couple millimeters = too low. I have no idea how I screwed that up, but all the checking did allow me to = simply build a new chunk of laminated cap, taper it from a couple millimeters thick to zero and epoxy that in place. Went back and checked = resulting bridge height again and found that my down bearing targets = were right on.</FONT></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><IMG alt="" hspace=0 src="cid:001201c5855d$19a47c30$0201a8c0@youro0kwkw9jwc" = align=baseline border=0></DIV> <DIV><FONT face=Arial size=2></FONT> </DIV> <DIV><FONT face=Arial size=2>I realize you could do the same thing = to a solid cap.
