I owe a big thanks to @BobKarnaugh and @procterc for their help on the Bridgeport tonight! Bob helped me square the vise (OK, let’s be honest - he did it). And the Bridgeport head was seriously out of tram (0.007" across a 1" sweep!) (EDIT: Across 2" sweep). Bob, Charles, and Sam re-trammed the head. (If someone knows Sam’s talk ID, please add it for me).
Thanks much, gentlemen!
