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! 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.) 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. I realize you could do the same thing to a solid cap. But there are a = number of unique processes employed here that allow these things to be = measured much more accurately than traditional methods. I can hardly wait for that notching machine!!! Terry Farrell Re your other post you sent to show the drilling for vertical hitches. = That looks to be a very nice bridge you've got sitting up there on the = Knabe board. Nice work SNIP Ron O. ------=_NextPart_001_0014_01C5853B.92954D30 An HTML attachment was scrubbed...
