It is, after all one that can be seen by every one.</font></blockquote> <div><br></div> <div>Before removing the plate, I drill two holes (~5/64")  in the treble and two in the bass to</div> <div>make  a pattern of the block perimeter.  Fit a large piece of paper into the corner  and cut</div> <div>for any angle between the stretcher and side. Punch index holes.</div> <div><br></div> <div>Once the new, oversize block is fitted and screws installed, drill thru the index holes into the new block, remove block and index pattern off the holes. Draw the corner on each end</div> <div>and connect the ends with a straightedge. This duplicates the exact dimensions of the old block. Cut out pencil line for the sides on a band saw, leave some pencil line on the front</div> <div>and dress on a joiner.   Side-to-side fine fitting is done with a file or belt sander.</div> <div><br></div> <div>Since the bass end only has a small area I want the bottom of the block to have full contact.</div> <div>To get the block in and out easily during fitting, sand away material from the top end on the bass and the bottom end on the treble; a parallelogram shape.</div> <div><br></div> <div>This will produce a fit with no sideways play.  If the bearing is OK, the block is glued</div> <div>on the three sides, then plate is then installed and the block screwed in place. Clamps</div> <div>press the assembly until the glue cures.  Then remove plate and install screws at each</div> <div>end into the inner rim.</div> <div><br></div> <div>I don't dowel into the stretcher, just leave the glue hold it. What good are a few small dowels anyway.</div> <div><br> Regards,<br> <br> Jon Page</div> </body> </html>
