I thought this might have been covered, but a search didn't yield anything helpful. I bought some Tanos T-Locs for some of my older Festools and some other tools, including my Kreg jig and accessories. I would like to put the Kreg stuff in an attic systainer (I bought one). The problem is that I really need it in a Sys 3, but the attic systainers are only in a Sys 2. Consequently, I would like to switch the lids on two systainers, to make a Sys 3 an attic systainer. Before I do something that might damage one of these costly boxes, can someone explain the proper way to remove (and replace) one of these lids? Thanks.
