wow quick response. yes i have no formal training or experience with proper milling tools. by your list it is the cross slide that is locked up, carriage,and compound rest work well. I have loosened all the lock nuts and gotten the slide mostly free, loosened the 2 collars behind the hand crank but it still wont budge.
thanks the Id plate was right ware you suggested(amazing what a little degrease will do )
