Yeah, I use a lift to pull out compressor out of the middle of a condensing unit or something like that, but my anvil (only 130 lbs), got placed on its "stump" by hand. I tend to only use a lifting device if its really convenient, and setting it up to do the job will take less time than to just do it, or if its just beyond my ability. I do hate putting the 90-100ish lb vises on and off the mill table, because I have to reach out with them. Puts a lot of strain on my arms and a little on my back. Actually those vises were my first thought for the chair lift when I got it. Clamp (made to hook under the jaw) a hook eye in the vise jaws, lift, and swing. -- Bob La Londe CNC Molds N Stuff -- This email has been checked for viruses by AVG antivirus software. www.avg.com
