Spruce rails for a new Cruiser build

To the woodpile for some long spruce, this second build will be true to the originals with lighter weight spruce rails. 

18' mostly clear stock, small knots can be hidden behind ribs and behind decks. Second grade boats allowed small imperfections, so long as they didnt affect the stength of the boat. 

Lots of potential rail stock

Last dip in the pool before its closed for winter - rails need to soak up before steaming for bending before mounting on the form

After this build, the next one will be made with hardwood rails and will be set up for sailing. Just completed is a batwing style hybrid lateen sail made by Todd Bradshaw of Addiction Sailmakers in Wisconsin. So much nicer looking than a standard lateen sail, total area is approx 49 sq feet. Now to find some 18' mahogany.
More to come on this project...

Rails for new build

Clear white spruce, milled from stock thats been air drying over a year. Kiln dried stock will no longer reliably take the bend it needs to once he cells are altered. Air dried lumber bends fine.


Nice straight grain


For a sheer with as much upturn as this model has, rails go on form the easiest if pre bent, then heated up again when mounted on the form


Bending around a form ensures uniform curves


On the form against the backers


Ribs are next


Soaking in the pressure tank overnight


Couple quick stands for the tank

Material Gathering

Just as birchbark canoe builders gather bark, spruce gum, cedar, and spruce roots, the building of a cedar canvas canoe requires the gathering of materials as well. In order to build authentic replicas of the early Chestnut Guide,  we are adhering to its original configuration and list of materials. White cedar ribs and planks will, along with maple for the seats, thwarts and decks are not difficult to source , and even white oak for stems has been procured.  What does prove difficult however is long lengths of spruce for gunwale stock, either for single, closed gunwale construction or for the later style of open gunwale with both and inner and outer.  Chestnut was building in both styles before the factory fire of 1921.  During a weekend north walking the woods hunting for grouse, we visited a sawmill who had 2 30' logs they agreed to mill for us in an attempt to pruduce some clear stock.  Ash gunwales, or even cherry or oak are not over scarce, but clear spruce in lengths over 17' are rare as trees are both smaller, and no one cuts in those lenghts.  Lumber piles yield large rafter stock, however it has always been kiln dried and wont bend well afterwards.

Starting to load - nice long stuff, much clear throughout.  

The write up of the Guide model early on specified that the lumber is not as selected as with the pleasure, and small knots and imperfections were allowed so long as they didnt weaken the board. As in many canoes, they can be hidden behind ribs where possible, however even our example has small knots visible in some areas. This was a Guides canoe after all, and with the heavier canvas it was meant for working.
