We created the internet-renouned Z-Bed this week. After months and months of searching for a used Westy Z-Bed without any luck, we decided to bite the bullet and do it ourselves.
We purchased the hinge kit from Bus Depot. It comes with "directions" that really aren't that helpful, they're also not converted into inches. If you did use all of the measurements, you'd quickly realize that the plans don't really add-up (maybe we were missing something!?). Also, the kit is only half of a kit, as it's missing all of the screws/bolts/nuts - so you have two options: A.) make sure to purchase the corresponding hardware pack or B.) buy them all yourself separately (there is a list of what you need in the instructions).
Overall, you can loosely use the instructions provided in combination with these dimensions from the Samba. Ours is shorter length-wise than the bench shown on the Samba thread because we are going to be installing cabinetry. We also already know that we are going to modify this original set-up to move the hinges down (but won't have time to for another two weeks). We'll update this post once we do so!
Create your bed base
Cut Seat-Back and Seat-Base, then apply hinges. Note that the seat back should be 1/2" shorter in length than the seat base in order for the hinges to align properly. Also, if you place your wood on the base too close to the hinge, you may need to chisel out some wood in order for it to swing into the lay-flat position (we did, anyway :p ).
Fold Seat-Back and Seat-Base into seated position, then mark placement of hinge on the base, and affix the hinge.
Jigsaw rounded corners and handle (optional)
Place in van and secure to Firewall. We found that we could re-use the old seatbelt holes and fixtures from the old passenger van seats in conjunction with a perforated metal bar because the thought of drilling new holes through the firewall wasn't all that appealing to us (seems too risky!). We also used 8 corner joints to affix the base of the bed frame to the floor on the inside of the base.
Enjoy the Final Result!
Bam! You've got yourself a bed!
As you can see in the last photo the bed is a few inches higher than desired. So we will cutting the two base side-panels down a few inches and moving the hinge down a few inches. We will be keeping the front panel at the height it is currently, so that the seat will have a slight angle like that of a passenger seat. Stay tuned for the update in a few weeks!
