View Full Version : recycled timber
07-13-2010, 11:56 AM
I am building a sof canoe and want to get 1/4" stringers out of a board of yellow pine which contains some nail-holes. How best can I deal with these, bearing in mind how thin the stringers are?

What I would do:
Guage the diameter of the holes. Get or make an appropriately sized dowel, and with epoxy, drive fit it into the hole, saw it off, go on to the next one. After all the holes are filled, go back with a chisel and pare the ends flush, both sides. Use a scrap of the pine for making the dowel. Depending on the size of the holes, you might even just use a toothpick or a kitchen match.

A lot depends on the value of your time, as I suspect a decent-sized nail hole will dramatically weaken a thin stringer -- even after the holes have been pegged. But if cost issues are paramount, give it a try and see what happens. Remember that any dramatic curves may be harder to make with old recycled wood, as it will have lost some flexibility and strength over time.

Depends how far apart the nail holes are. I'd consider scarfing the longest clear lengths after cutting out the nail hole from the sawn stock. 1 : 12 scarfs with epoxy or resourcinol glue will be as strong as virgin timber.
