i recently built a laminated tiller, it was fun. first I built a simple wooden jig on a piece of plywood, then I ripped strips of maple to about 1/8 to 2/6 thick. then using west system epoxy with microfiber additive for laminating strength I proceeded to glue and clamp two strips together and to the jig to give them a desired curvature. it takes about 6 hours for the glue to set and the bond joint gives it the strength to retain the shape, no steaming required. I then added more layers one at a time, I didn't do them all at once because the forces on the jig would be too high as the wood is strong and resists bending, so a 1 inch thick section would have been too much, After the last layer I planed it to shape and sanded it, used a table saw for the joint to the rudder and coated the whole thing with epoxy to water proof it.the laminations can be different color wood to give it a nice apppearance. this was not hard to do every 6 hours spend 15 to 30 minutes on a layer so in a weekend it is done. it is also cheap, my guess is a finished tiller of comparable quality would cost 25 to 30 dollars, this used scrap lumber and a few bucks of epoxy. let me know if you want to see a picture of itdave
