Quoted from RDBowers:Fishing with a coat hanger hook. That would work for legs with big bolt holes. I was thinking that might be an option as I was pulling legs out of the tube this morning.
I was planning to use it for other parts as well, like a lock bar mechanism or the channel used to restrain the upper cabinet back door for EMs. They don't have big holes to hook and are considerably shorter than legs. The tube I constructed is 36 inches, so I would have to reach down in the tube 16 to 18 inches to get a grip on them.
I have a length of 3" PVC pipe, so I am going to try building something tonight.
Screwed strong magnet to a 2' length of 1 X 1 wood. Works great.
