Recreation of the timber stretcher is not necessary. We found one of these
timber stretchers under the flooring planks of a barn in Blue Hill, Maine.
Well, I say, "we found one" but we have not actually gotten a look at it yet.
Every time we pull up a plank and try to peer under the edge of one of the
neighboring planks to see the stretcher, the plank stretches out to cut off
our view. We tried this a dozen times and before we knew it the barn had an
entirely new floor. We called in the local codes enforcement officer to
observe this amazing phenomenan. He immediately put a stop-order on
observations citing the possibility that if uncontrolled observations
continued the entire town would be decked over .
