In this video we cover basic operations of a J head bridgeport, just showing you what the levers and knobs do. It's easy to forget what's what when you are in a hurry, so be careful when you are getting started!
There is, but you have to go to the early 2000s BBS (pre tap talk days!). It's buried under all the crap unfortunately. The detailed operators & service manuals are available and extremely helpful. I'd suggest never doing spindle bearings unless you have the manual in front of you.
@rickjohnsonjr8954 I lean on it very hard for boring. On my machine it's extremely difficult to change speeds when the machine is not running. I should probably read a manual and make sure it is not causing damage haha
