Here is the loft bed plan that I've come up with. Please feel free to use this as you like. If you re-publish these plans please reference my blog URL. I hope someone finds these helpful. Email me or post a comment if there is something that is unclear. I'll posts some pictures of the different parts of the bed too. Hopefully that will clarify.
Materials & Cut list
5 Rungs - 19" (1x5 pine)
5 posts - 80 1/4" (4x4 spruce)
8 end boards - 48 3/4 (1x5 pine)
4 side boards - 75"
2 side boards - 55"
2 side mattress supports - 75" (1x2 pine)
2 side mattress supports - 40" (1x2 pine)
1 bottom plywood for mattress support 40x75 (3/4" plywood)
4 bottom supports - 40" (1x3 pine)
12 screws - 1 1/4"
20 screws - 2"
60 stove bolts - 4"
60 screw cover knobs - 3/4" (or whatever size holes you have)
- Counter sink stove bolts and cover holes with knobs so that bolts aren't sticking out. I used a 3/4" bit to countersink.
- Glue and screw the support rails on to give added strength
- The bottom supports can be out of any size wood and the plywood could be skipped if you add more bottom support rungs.
