I found it necessary to pre-bend the ribs by steaming them, slight bending while still hot and supple, working from on end, until I could feel they weren't bending any longer. (yes I did crack a few until I got the "feel" of the bending). Then the ribs would go back into the steamer to soften up again.The sharper the bends the longer it took to work them. Don't be in a hurry to get them glued and clamped, but when you get a rib ready for that final step, it may be best to do it while it's still warm and supple. If you have enough pre-bend in them, they clamp into place nicely and remain there. Also 4 hands are better than 2 during this phase, and applying the Dacron.The second question about transporting, no I don't think it will hurt the frame a bit, in fact I would use lots of thin rope and lash them tightly down, but not tight enough to distort the shape of the hull. In fact I would probably leave the frame on the strongback with the stations still attached to ensure it holds the proper shape. Covering it with a tarp also wouldn't be a bad idea in case you run into some heavy rain.Good luck, sounds like a great project to pass the time and relax up at your cottage!Rick

Subject: [Airolite_Boats] Ribs
I am concerned that the ribs I am putting in my Snowshoe Lassie may be deforming the shape of the canoe. Rather than build a steam box I opted to use the boiling water, wet towel, bubblewrap system. The two ribs bent fairly easily and did not break, but they did have some difficulty getting right up into the chines at the bottom of the sides. When I got them where I wanted them,they pushed the stringers and the keelson away from the molds.
Is the problem that I am not getting the ribs limber enough?
And a simple question: I am going up to our cottage in Canada (400 miles) next week; I won't have the skin or the roving on by then.I will have the ribs in and glued. Does anyone see any issues in transporting the canoe on my rack in that condition?
