I can make ideas in my mind, but it’s usually easier to refine and revise them on paper. After that, I make a scale drawing on the computer, to see the size of individual parts. Here’s the process in regards to a large steam bender I want to make.
I start with light pencil lines, when I’m sure where I want a line, I make it darker. The scale computer drawing not only shows the size of pieces, it also helps me decide the height above the ground. The whole box needs to be angled, so that steam rises to the end opposite the steam inlet. But I had to be sure that a twelve foot long board wouldn’t hit the ground when removed.
I need this box not only for bending wood, but also for heating it, to kill parasites that might be living in it. I will sell not only finished wood items, but wood blanks for DIY guys to make their own.
