I have an old tractor front-end loader that I'm going to be doing a major overhaul on in the next couple of months and it will require at least two line-boring tasks across the width of the loader frame; i.e. two bores about 1200mm apart and each about 100mm deep, that have to be in perfect alignment. I'm at the stage of daydreaming about how I am going to set up the line boring. I would be very interested in seeing what setups people have done, in particular how you have applied feed to the tool. I have an old drill press that I can use for both power and feed to a boring shaft but I think it will be difficult to get a fine enough feed that way. Keen to see how others have done it.
