Curious about Wooden Canoes
Hello cup washer friends! I have a follow-up to my previous post. I received the #8 brass cup washers from Lyman's Boats. They turned out to be an exact fit onto the profile of the #6 screws I'll be using for the keel of my boat. So... it didn't suit the purpose of keeping the screw from pulling deeply into the wood and filling the countersink in the wood. On the bright side... my fear of having my # 6 screw pull through a #8 washer were unfounded. I ordered a new set of #10 washers to see how they would do. My assessment is that they do very well! They are slightly smaller than the original (by 1/16 of an inch) but they fit the screw well and even allow the screw head to be below deck surface. In the photos i have only lightly tightened these down so they still sit a little proud. There is a slight flange on the top edge of the washer that is smaller, but mimics the original. I'll include photos to this post. Let me know if you have any questions. So far, I think these are the ticket for my boat.
