Hello Gerhard,
first I want to say that your three-way-bed is fantastic!
I would like to build this three-way-bed too. But I have got some questions:
1. Where do you mounted the pneumatic cylinder at the foot of it?
2. Where do you mounted the second pneumatic valve for this function?
Could you please take some pictures for me?
Especially I would like to get a detailed view of the under side of the bed, the modifications you have made on the frame and the mounting of the cylinder at the bed.
Thanks for your help!
Greetings,
Bastian
