<BLOCKQUOTE cite="" type="cite"><FONT face=Arial color=#000000>I would love
to read procedures for nailing this left, right, tight at both ends fit. 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>
