The time has come to install a new oak keelson in the old all-wood, strip built, Peterborough-like canoe I have been restoring. Not wanting to lay on the floor underneath the canoe and drive nails upward with weights on the keelson, I'm thinking about driving a half dozen screws thru the bottom & into the keelson to pull it tight and hold it in place. Then, with the canoe turned over, it should be much easier to pre-drill and drive in the hundred+ nails. Have I missed something? Is there a better way? I found no evidence of bedding compound underneath the old keelson. Should dolfinite be generously applied underneath this new keelson? Tom McCloud
