Below is a picture of the system/parts/tools I am using for plate support and adjustment. Pretty = much the same as Ron N and others, except I think I interject a little bit of = overkill for better sleep. As someone pointed out, often the original screw holes = are not very straight. So I just drill them out with a half-inch bit and = epoxy in hardwood plugs. Then I line up the plate properly and drill nice = straight holes with my overhead drill press. Then I tap the holes (tap - with extension = - is the long silver thing on top). I have a long hex bit (lower right) = that I chuck into an electric drill for most of the screwing action. Then I use = the red-handled hex-bit "T" driver for fine-tuning the height. = Three of the 4" x 3/8"-16 set screws are on the lower left. The left = most is bare, the center one has the thin nylon lock nut that the plate sits on, = and the right one has the acorn nut that goes on top of the plate (I also = put a ss washer between the acorn nut and the plate). This system seems to work = quite well. </div> <div>   </div> <div> Terry = Farrell </div> <div>   </div> <div> <img width=454 height=341 src="cid:image001.jpg@01C5AEC5.CD9DFA40" align=baseline = border=0> </div> </div> </body> </html>
