There have been a few posts about reclaiming old posts and timbers with
the following caveat; remove all nails before sawing. Well this only
makes good sense. My question is, even if the nails are removed, could
there be sufficient residual corrosion in the holes to shorten the life
of planer or jointer blades used to finish up the resawn pieces?
That's all, just a question, but someday I might get lucky enough to
reclain some old/used stuff.
If there are visible debris in the holes you could drill the holes out
larger to remove the debris or cut the holes out if they are near the edge
of the board. I do this with unwanted knots so that I don't take a chunk of
the knives by hitting the knot.
I pretty much assume that I'm going to do some damage to the cutting edges
of tools when I work with reclaimed wood... nicked the iron on my L-N 7 on a
bit of metal that I missed in a piece of reclaimed old growth pine a few
weeks ago. That really annoyed me as the plane was only a few weeks old!
I'm one of the old timber posters...another thing to consider is when we
process new KD Beech, we often find plenty of bullets. The lead isn't too
bad on the tools but it makes me think that the old timbers are also full of
bullets. Take down my building and you can HAVE all the old timber!
It's worth the effort, IMO, but ... old wood can sometimes have
debris in it that is not visible. It's not unusual, depending on
where it came from, to come across pieces of barbed wire,
staples, nails, all kinds of things that the tree simply grew
around over the years. So, there's a certain amount of gambling
to it but in general I think it's worth the gambles.
I've missed some stuff with my metal detector... things like broken screws,
nails, staples, chunks of rust, and small tacks. These kinds of things leave
little nicks in the knives... not great but not terrible either if you view
these tools as dimensioning tools and not as finishing tools.
Ok, thanks for that information. I was under the impression that current
technology for (at least what is available (read affordable) to the
consumer) was more efficient that that. I guess that won't happen until MRI
machines are down to the price of consumables. :)
Current metal detector technology is that good but you won't find it in the
typical cheap wands that woodworkers usually have. Look at $500.00 or more
and you will get something that won't miss stuff. A friend of mine (a
prospector) just bought one for $1200.00 that will even identify what kind
I have found that even new wood that has sat around or has been poorly
looked after tends to have dirt and small stones embeded in the wood that is
hard on planer blades. Best keep two sets at least. One for rough work and
one set for finish work. It even pays to power wash some stuff.
