I have to do some work behind the back panel of my LOTR this weekend. What do you guys use to hold the back end up (so that the PF lies nearly flat on the front lip of the machine)? I had a tech come once that had a wooden shelf he slid in and rested the PF on. Is there any place with specs on how to build one? Or is it just something I measure out and build myself? Thanks for any help!
