I have a medium size vise , 4" as I recall. It is burried but I will
unearth it and give it a try. I realized it was difficult for my helper to
hold it steady while I used 2 pipe wrenches. I have an 18" pipe wrench and
a tube I can add for a bit of extra lever arm.
I don't have a high opinion of my skills with a dremel tool, I may get
experienced if it comes to that.
Thank you for your reply!
