We wanted a modern platform bed made from slab wood about 3" thick. These were impossible to find for purchase without spending many thousands of dollars. So what the heck, it can't be that hard to build a bed frame - right?
As it turned out this was an easy project, only made somewhat more difficult by the weight of the wood I chose to use, which resulted in a bed weighing about 275lb and which I therefore had to build in such a way that it can be easily disassembled for transportation. Next time I will use Port Orford Cedar throughout which is much lighter and should get the weight down enough to make it practical to build this as a non-breakdownable bed.
I purchased a slab of Eastern Maple already cut into 4 boards from a local yard that specializes in slab wood. I wanted the bed to be an oversize Queen Size with the platform protruding about 6" on each side of the bed. Initially I wanted the foot of the bed to protrude 12". Unfortunately the destination room is too shallow for this but it would have been a nice touch to have been able to use the foot of the bed as a shelf for books or decor items. I had two Port Orford cedar boards left over from another project that I would use for the legs.
After cutting the 4 planks to length I marked and cut the simple Rabbet joints. The lumber was too heavy to risk using a dado blade on my table saw so I cut and chiseled the rabbets with a circular saw. Next time I will have to come up with a quicker and more accurate technique for this step.
