Hi All, Mike Blackwell has now witnessed what happens to lead tubing
when it becomes so oxidized inside that the tubing just breaks or
'falls' apart [001014 MMD]. The term I use to explain the phenomenon
is 'explosion', since it looks like someone placed a tiny bomb inside
of the lead tubing, causing it to expand from the inside out. Why this
happens is food for another posting. The white dust is lead oxide.
To answer his question: The lead tubing is glued directly into wood.
As to what to do now that the lead tubing is useless, the answer is:
replace it with either new lead tubing or rubber tracker bar tubing.
To accommodate the fact that there is no nipple on the tracker device,
you can buy a reducing nipple that goes from the O.D. of the old lead
tubing to the I.D. of the tracker bar tubing.
