I've been needing a bed for our spare room for a while now and it turns out anything I liked was waaaaayyy out of my budget. . I've seen a few sandblasted Oregon beds around that I like the look of and finally found one in a shop that was pretty close to what I was after, but at $4000AUS it was definitely too expensive. So I thought I'd make one.
All up I think it cost me ~$500-$600 so it's still not super cheap. I'm sure with some good scouting you could do it for a lot less with found timber.
Step 1: Google Sketch-Up Modelling
I jumped on Google Sketch-up and mocked up a rough template for what I was after, and ended up with this.
You'll need to get this program if you want to really look at the model in depth. I've included the .SKP files so you can see exactly how it's been modeled. There are measurements for everything on the models and they are all drawn in the size they needed to be when built.
From the model I worked out that I would need:
(240 x 45 x 2480) x 4 - For the top and sides of each side
(240 x 45 x 1360) x 6 - For the bed head and the foot
(195 x 45 x 610) x 2 - For the sides of the bed head
