If you think making boxes or turning pens is addictive wait till you get into wood bending, it opens up so many creative possibilities. Try steam, there are lots of good free resources on line, then there is the method using dry heat, then there is glued laminate and for the more adventurous there is the ammonia method. From there you can get into vaccuum forming and cold molding. You do realize wood bending will ultimately lead to boat building don’t you?

I use bent wood lamination. Resaw thin pieces run them through sander making sure to keep the pieces in order for grain matching, spead glue evenly over mating surfaces and clamp int a bending form made from MDF and lined with cork and plastic packing tape. This seems to work well. I’ve never tried steam.

Ya ~ I’ve done a bit of bending; laminated and steam. Both are interesting.
http://lumberjocks.com/projects/6299 Here is a laminated Arbor that I built for my back walk way: 9 layers, cold bent, polyurethane glue, great fun sawing on the band saw. Had two brains running 4 hands ~ and it was big. Reminds me of sawing boat frames. Here are the pics# of the actual bend operation. I needed a lot of clamps.
I’ve also done a fair amount of steam bending. Steam it in the “Box” for 15 minutes per 1/4 inch of thickness (or 1 hr/inch). Extra time and heat will just make it brash (brittle). Expect some failure ~ some will break, some will splinter bad. Steaming green wood works best if you can get it. KD has inherent problems but will work if you are willing to put up with a higher failure rate.
Adding a “back strap” will help on any bend. Usually made of sheet metal, it goes around the outside of the bend and because it will not stretch, the neutral axix of the bend is moved twoards the inside of the bend, putting the wood under more compressive forces than tensive forces. Wodd will endure compression better but still has limits. Some woods bend better than others: ash is great (snowshoes) and a lot of woods just plain won’t. Have fun with it.

Never done it but would like to gather the skills.
