I'm a newbie (this will be apparent upon further reading). I bought a used Kurt D80 8" vise thinking why wouldn't I want more capacity. OMG, this thing is massive. I now realize I probably need a 4" vise for my benchtop mill (Rusnok style). Anyone have any suggestions for trading down! I'm hoping I can trade for a similar quality, but more reasonably sized, vise. I suspect shipping would not be an option as it weighs over 150 lbs and I have several sets of jaws probably bringing shipping weight up to nearly 200 lbs. Any ideas welcome. Thanks, Brendan
