<DIV><BR></DIV>
<DIV>I've never heard of or seen anyone do that. The normal way to
provide an escape for the glue is to score a line down the top of the shank
for 15mm or so, but even that is not necessary if the knurling provides an
escape route.</DIV>
<DIV><BR></DIV>
<DIV>A good knurler is essential, and if, as in Ed Miller's case it is
impossible to knurl the shank to a fittable diameter without splitting the
shank, then either the bore is too small or the shank is too fat. In
this case I knurl once, then whittle away the knurling with a knife working
with the blade at a right angle to the shank and then knurl again.</DIV>
<DIV><BR></DIV>
<DIV>A tool for scoring the shank is very easy to make : in a piece of
hardwood cut out a channel 6mm. wide and 6mm. deep; bevel the end of a nail
and drive it up through a hole bored centrally in the channel.</DIV>

<DIV>To score the shank, drag it along the nail with some pressure.</DIV>
