A milling machine trick you have to see!
This is a tip for squaring up your vise fairly accurately without spending time using a test indicator each time. At the time I shot the video, I was still drilling and countersinking the holes in the keystock and drilling and tapping the vise. The fit is very tight, and the test indicator shows it to be off by only .0005″, which is about 4 times better than what I really need for what I use my mill for! This is my best machining time saver yet!
