After just 2 days of milling, one of the bolts holding the two halfs of a belt arm came loose, locking up two of the arms (they only moved together because the bolt that fell down locked both in place).
In the photo you see that the locking bolt are barely engaged causing them to get loose. I now applied a dab of loctite on each. Let’s hope they stick now.
Maybe these should be longer bolts?
