Folks… I am looking for different ideas about how can we make the mounting stands that bolts onto the concrete floor, removable ? I searched on here and I read that someone achieved that by pouring the concrete over a square tubing …etc… well it must be good to build your own shop I guess, but how about the existing concrete floor ? How can we make that happen.? Im planning to get a few stands bolted down on concrete , but geee it would so nice so I can put them there whenever I want them, in case a big object is being moved around there. I thought of making a lets say 3 inch diameter hole into the concrete pad and about 14 inch deep and insert a heavy duty steel pipe in there and have it flush by the concrete surface, then drop my mounting stand into it… well, then how to secure it ?. so it doenst spin or pull out with some wiggle ,push, and pull on the mount ? any ideas , pictures is highly appreciate it. cheers Falco.
