Nice. I read the board weekly. I had not come across this engineering marvel. The rear was already safely positioned before I realized the access issue. Only a set of hex bits were available. The 3/8 drive set has enough length to use a wrench. An 8mm worked. I did have to tap one with a ratchet to loosen up the slide bolt.
