Have tried one many Years ago-although you can still buy it-with a VERY BAD result. The old fashion way is absolutely the best. Some make a draft -from the Plan, and set this behind the faster through. I did it in another way. To planking list -a bit longer than the bottom, cut down to the size of each place to make knots. One on the backside and the other on the front. At the end of each side. A pair of Close pins held them in place. One done, move up one step and so on. This way it is much easier to make the knots.
Sorry for resending it, but to many spelling mistakes.
