Hi everyone, I'm just getting started. I've gathered all the tools, read Fletcher's book about 6 times (so great), and read quite a lot of these posts (also great). I've decided to build a 17x54. Went to the lumber dealer in town, and decided i'm definitely going to use the Hydrotek BS 1088 6mm for sides, and 12mm for floor. I'm going to use Mahogany for the Stem. I'm planning to use Port Orford Cedar for the frames, and was thinking i'd match that with White Oak for the rails/chines. I hope to have the boat for the rest of my life, and while i want it to be the most beautiful boat ever built, I truly want to use materials that will last and be effective. So, first question... Instead of White Oak, anyone ever use Port Orford for rails? It seems like the color would be similar to White Oak, but i wonder about durability as a rail. appreciate any insight you might have.
Looks good dusty
areas where boat will take impacts....rocks, oars, etc...cedar is prone to easy damage. Better to use a harder wood, like oak, mahogany, ash, maple. They'll still get dinged up, but at a much slower rate.
Choosing white oak for my chines. Sounds like I'm asking for trouble if grain run-out is less than 18 inches? Can someone explain how to measure that? i can't seem to find a good explanation
The chines and chine logs have the most severe bend of any parts in the boat. Excessive grain runout would cause these parts to break when bent. To get a feel for this, take a short piece of 1"x3" and stand it vertically. Take a wide chisel and orient the blade parallel to the 3" edge of the wood and split the piece. If the split runs parallel to the edge of the board, there's no runout and you'll end up with two roughly rectangular pieces - on the other hand if the split "runs out" of one of the flat edges of the piece, you'd have a problem trying to bend it. Once you understand the concept, it's fairly easy to examine the way the grain runs through the board and determine whether it is a good candidate for bending.
Those clamps are sick! What are they?
ABS pipe with a slit cut in them.
Yep, Rick is correct. Had an old pipe laying in the back of the property and a friend suggested that i could make about 50 effective clamps out of it. Didn't believe him, but went along with it. Was completely surprised how much clamping force these little guys have. It has been super effective for a few applications like the pic above.
You can stack them on top of each other for even more force in a small area!
