spinedoc, I can empathize with you about the jack. I have always has the same complaint about the jack slipping, but refrained from replying earlier since I could not contribute anything other than "Me too".
The Craftsman jack idea is a good one. I'm goint to go check them out this weekend.
I guess that's why I check the forum throughout the day. Thanks once more to all of you.
