- Nov 16 9:01 AMChief,I'm always curious about trees, do you know what kind of cedar it is you are referring to here?That is really interesting about pine and Titebond II.Here in the land of Douglas fir, in the Pacific Northwest, we are seeing more and more pine. The nice Douglas fir wood came from old growth that is mostly gone now, and it takes that species a really long time to produce large trees with lots of clear heartwood. The pines in the south seem to grow faster, and so I think the pine tree farms there produce more wood per acre per year than the Douglas fir tree farms here do. So it seems likely we will be seeing more pine here as time moves on.When I grew up, pine was considered adequate for cheap disposable uses of wood. However I'm fond of pine and much of my furniture is made from pine. Part of the inside of the home I grew up in was paneled with tongue and grove pine. So I'm inclined to use pine, where it will work well.These days a lot of the "fir" here is actually hemlock, which I don't like as well as Douglass fir or pine.So its good to know you think well of pine for boats. I think I'd rather use high quality pine than trashy fir, especially if it isn't really fir in the first place. Also pine is lighter than fir, which is good for small boats you move around by hand.We have a lot of really damp cold weather here. If stuff in an unheated uninsulated shed gets really cold, and then a foggy drizzly warm front comes through, a layer of condensation will form on the cold surfaces inside the shed, and the tools tend to rust a bit from this.You would think that tools in sheaths would trap this moisture and rust worse than the exposed tools, but it doesn't work that way. I don't use rubber sheaths, they are either leather, fabric, or carpet and so are permeable to moisture and will dry out if the tool was wet when it was put into the sheath. The sheathed tools in my shed don't rust the way the exposed metal on other tools does.So whether the moisture condensing out on the boats is frozen or liquid, it seems like covering them with blankets would help protect the wood from picking up moisture from condensation when they are in storage.May your day be filled with clarity, grace, strength, insight, balance, cooperation, and warm laughter,Roger----- Original Message -----From: "Chief Redelk" <chiefredelk@...>To: <email@example.com>Sent: Thursday, November 14, 2013 11:45 AMSubject: Re: [Bulk] Re: [bolger] cedar paneling> I've cut a lot of Cedar trees..
