[QUOTE="PeterT, post: 16297, member: 22"] Is the issue you are trying to solve basically annoyance with backlash, or is the spindle floating & you cant hold a depth setting milling? My RF-45 mill down feed was reasonably tight & smooth but the depth indicator was completely out to lunch. I attached various DRO's over the years, least expensive of which was a re purposed digital vernier. As long as I locked the spindle during milling it held fine was reasonably accurate for progressive depth cuts. Even in drill press mode the backlash will taken up one way or another when the cogs mate once it sees resistance from the work, as long as depth can be zeroed & measured with some independent indicator. What is the purpose of the cogs to begin with do you think? I wonder why it couldn't be a single slot keyway for example? [/QUOTE]
